NXP i.MX 8 DV — alive and kicking

The team at NXP have really impressed me with how quickly they were able to bring up the new i.MX 8 DV. If you haven’t heard about it, the DV is a development vehicle that NXP introduced in advance of their upcoming family of i.MX 8 processors, and this thing is a beast.

Mapping closely to the upcoming production device, the DV sports dual A72 and quad A53 cores, along with a host of M-cores and dual Vivante GC7000XSVX GPUs. Combined graphics processing jumps sixfold over the previous generation of i.MX devices. The device also has a strong hardware isolation story: 16 partitions are available to map the various hardware blocks on the device and guarantee isolation between them. This architecture greatly facilitates virtualization and even the ability to partition hardware independent of a hypervisor.

Why is this so great? Chips this powerful can span multiple displays in the vehicle. You could have an infotainment system and a digital instrument cluster running on a single i.MX8. Because you don’t have to worry about virtualizing a single GPU (which is quite the challenge), you can carve up the chip’s graphics and processing power to isolate the infotainment system from the cluster. This, in turn, minimizes your scope of certification. Achieving ISO 26262 for a cluster is daunting enough; achieving it for a complex infotainment system as well is off the scale.

This device marks a change in how QNX Software Systems and NXP work together. For the first time NXP is bringing up a new chip on the QNX OS and Linux in parallel. Usually, Linux come first, but not this time. I am, needless to say, delighted by this level of cooperation between our two companies.

At FTF, NXP demonstrated the i.MX 8DV, and it looked great.

Proton Wira upgrade - progress update May 2016

A number of guys have been asking me how my Proton Wira upgrade is getting along and my answer is sadly, "Not much".

Since my last update: Proton Wira modifications under RM1K project: Part 2
I have made very few upgrades to my Dad's old Proton Wira which has in fact become my car - to drive to Work, fetch the kids from school, etc. The main reason behind the delay is probably because of my stubborn insistence on doing most of the work myself - DIY, and various other reasons - too busy with work and the kids, lack of a proper garage at home to work in, lack of tools, blah blah but I realise most of them are excuses I make to myself.

The thing is that I have a conflict in my head/ heart going on deciding whether it is worth it to spend so much money on an old car when I could just put it down for installment on a brand new car which comes with no headaches for at least 3 years. Maybe it had to do with the numerous people telling me to get a new car, including my parents and even my daughter.

There were a few incidents as well - the car air conditioning started having problems and then I noticed engine heating up. Later I found out that the fan was not working and had to get it changed. Then a lady reversed her car onto mine - fortunately the damage was not that bad and I it took just half a day to get the bump repaired and repainted at the paint shop near my house. Finally, the dreaded power window failure happened. Now the right hand window can't go up or down. Just made me realise how Proton's lack of quality control, especially with regards to the power window, totally destroyed customer loyalty and lead to the troubles it is currently facing now. However, the fact that I have no debts makes me really reluctant to get a new car - I will be paying off debts to the banks for at least 6 years.

If I do eventually buy a car, it will be paid for in cash and I plan to buy a Mercedes A class, or maybe a BMW 1 series. I prefer a small zippy car. However, it is definitely going to take some time to accumulate the amount of money needed and who knows, by then we would all probably be using driverless cars by then.

 I did have some work done.

 1. I changed the emblem in the front from the green - golden one to the new silver-black one. I got it cheap at Brothers. Definitely looks better.




 2. I also changed the old worn out gear stick cover to new ones. Bought the new cover online on Lelong.com.my. Installation was fairly easy.

 3. I then had my steering wheel changed as well to a Fake Momo from Brothers. I have no idea how they can get away with selling fake items. Fitting it was also a pain as their workers (new staff) took ages to fit it on my car.

I hate fake stuff and ended up regretting buying the steering almost immediately. I tried removing the Momo logo sticker on the middle of the steering wheel and it now looks terrible. This is something I have got to change soon to a genuine Momo steering or maybe a Nardi, but spending about RM 500+ on a brand new steering wheel is something not on top of my priorities right now.



4. One thing I knew I could do myself quite fast were the pedals. So I bought Ralliart pedals from the Maxaudio site and installed them myself. The easy part were the clutch and brake pedals. However, to install the accelerator pedals, I found out that I would have to drill holes in them. In the end I ended up super-gluing them on - using super strong Araldite glue.


5. Finally I had Ultra Racing strut bar installed in the front. I thought I would do myself but I could not shift the crews even a few mm and finally had to go to my favorite garage where Paul and his team installed. The car handing dos feel better with less body roll after the installation but I may be imagining it.


I have a list of things I plan to do on my car, so wait for my next update.

A matter of convergence: building digital instrument clusters with Qt on QNX

Tuukka Turunen
Guest post by Tuukka Turunen, Head of R&D at The Qt Company

The Qt application framework is widely used in automotive infotainment systems with a variety of operating system and hardware configurations. With digital instrument clusters becoming increasingly common in new models, there are significant synergies to be gained from using the same technologies for both the infotainment system and the cluster. To be able to do this, you need to choose technologies, such as Qt and QNX, that can easily address the requirements of both environments.

Qt is the leading cross-platform technology for the creation of applications and user interfaces for desktop, mobile, and embedded systems. Based on C++, the Qt framework provides fast native performance via a versatile and efficient API. It’s easy to create modern, hardware-accelerated user interfaces using Qt Quick user interface technology and its QML language. Qt comes with an integrated development environment (IDE) tailored for developing applications and embedded devices. Leveraging the QNX Neutrino Realtime OS to run Qt provides significant advantages for addressing the requirements of functional safety.

There is a strong trend in the automotive industry to create instrument clusters using digital graphics rather than traditional electromechanical and analog gauges. Unlike the first digital clusters in the 70s, which used 7-segment displays to indicate speed, today’s clusters typically show a digital representation of the analog speedometer along with an array of other information, such as RPM, navigation, vehicle information, and infotainment content. The benefits compared to analog gauges are obvious; for example, it is possible to adapt the displayed items according to the driver’s needs in different situations, or easily create regional variants, or adapt the style of the instrument cluster to the car model and user’s preferences.

A unified experience — for both developers and users
Traditionally, the speedometer and radio have been two very different systems, but today their development paths are converging. Convergence will drive the need for consistency as otherwise the user experience will be fragmented. To meet the needs of tomorrow’s vehicles, it is essential that the two screens are aware of each other and interoperate. It is also likely that, while these are converging, certain items will remain specific to each domain. Furthermore, the convergence will help accelerate time-to-market for car manufacturers by offering simplified system design and faster development cycles.

Qt, which is already widely used in state-of-the-art in-vehicle infotainment systems and many other complex systems, is an excellent technology to unify the creation of these converging systems. By leveraging the same versatile Qt framework and tools for both the cluster and the infotainment system, it is possible to achieve synergies in the engineering work as well as in the resulting application. With the rich graphics capabilities of Qt, creating attractive user interfaces for a unified experience across all screens of the vehicle cockpit becomes a reality.


Cluster demonstrator built with Qt 5.6.

Maximal efficiency
Qt has been used very successfully in QNX-based automotive and general embedded systems for a long time. To show how well Qt 5.6 and our latest Qt based cluster demonstrator run on top of the QNX OS, which is pre-certified to ISO 26262 ASIL D, we brought them together on NXP’s widely used i.MX 6 processor. As the cluster HMI is made with Qt, it runs on any platform supported by Qt, including the QNX OS, without having to be rewritten.

The cluster demonstrator leverages Qt Quick for most of the cluster and Qt 3D for the car model. The application logic is written in C++ for maximal efficiency. By using the Qt Quick Compiler, the QML parts run as efficiently as if they too were written in C++, speeding up the startup time by removing the run-time compilation step.

The following video presents the cluster demonstrator running on the QNX OS and the QNX Screen windowing system:



The QNX OS for Safety has been certified to both IEC 61508 SIL 3 and ISO 26262 ASIL D, so it provides a smooth and straightforward path for addressing the functional safety certification of an automotive instrument cluster.

Qt 5.6 has been built for the QNX OS using the GCC toolchain provided by QNX Software Systems. The display of the cluster is a 12.3" HSXGA (1280×480) screen and the CPU is NXP’s i.MX 6 processor, which is well-suited to automotive instrument clusters.

Our research and development efforts continue with a goal to make it straightforward to build sophisticated digital instrument clusters with Qt. We believe that Qt is the best choice for building infotainment systems and clusters, but that it is particularly beneficial when used in both of these. Please contact us to discuss how Qt can be used in automotive, as well as in other industries, or to evaluate the latest Qt version on the QNX platform.

When Detroit looked like Silicon Valley

Mike Smitka

Autos are today a hi-tech industry; more on that in subsequent posts. The same was true circa 1900.

A quick window on the contemporary mindset lies in the pages of Scientific American. The late 19th century was the world of Thomas Edison (incandescent lighting was first used in the 1880s), of Dunlop and rubber (1889) and bicycles (1885 for the first chain), of more powerful (steam) locomotives, of battleships and bridges. Searching the titles shows only scattered mentions of automobiles. During the first half of the 1890s, the hot topics were developments railroads, followed closely by marine transport, and then steel and electricity. By the end of the decade, topics electrical dominated, with railroads close behind, followed by bicycles and then ships. Electricity remained the hot topic at the start of the 1900s, but now automobiles came in second, followed closely by ships. Railroads were fading as an area of interest for technologists of the era; bicycles were a mature technology. The last four years of the decade saw electrical developments as the most common, followed by railroads, automobiles and ships. Throughout the period 1890-1908 advances in transportation were presumed a major interest of readers.

Detroit was the Silicon Valley of the 1905 era

So did the venture capitalists of the day. Ford's first commercial attempt at making automobiles (1899) failed within 2 years, and he soon left a second venture in the hands of unhappy investors to found today's Ford Motor Company in 1903. That startup began with $28,000 in seed money. That was a tidy sum – a $2.50 workday and a six-day workweek meant a decent job paid $750 a year – but not out of reach for wealthy investors.

Ford was not alone in this. While the modern automobile originated in Germany, and many of the key technical advances were then made (and first commercialized) in France. Europe though was fragmented, and remained so through 2003, when the end of the Block Exemption finally allowed a fully integrated market across the continent. The U.S. was a bigger market, unimpeded by tariffs and in sheer numbers a larger middle class, the China of its day. Entrepreneurship was everywhere – new towns needed their retailers, farmers needed to sell their produce to people who could store and ship it, and provide financing; reapers and other new-fangled agricultural implements needed sales, financing, repairs. Dynamism is both provides the opportunities and is an outcome. Cars were just one avenue.

As with Silicon Valley, the industry was populated by serial entrepreneurs and networked individuals. For the US, Thomas Klepper [2002] analyzed data on 725 ventures for which sufficient records survived to confirm that they sold at least one vehicle. (Others have subsequently expanded that list.) About 120 were manufacturers of other products that tried their hand at cars; another 145 were spinoffs from existing car companies. Finally 108 were headed by entrepreneurs with prior industry experience. In total, just over half of all ventures were part of this broad start-up community.

Early entrepreneurs had to battle with the physical layout of cars, which gradually evolved away from being mere horseless carriages, and with what would provide the motive force – steam, electricity, or internal combustion engines. It took until 1903 for the industry to focus on the latter. Who would buy cars? The early market was partly for well-heeled enthusiasts, spurred on by racing. It took a while for them to become practical, but by 1905 there was a reasonable chance that someone would be able to both get where they wanted to go, and return. Dreamers could easily point out the limitations of horses: costly to keep up, a public nuisance because they were inefficient in eating [almost a pound out for a pound in], limited in distance, and needing a wagon to convey more than a single rider. Automobiles were touted as the way of the future.

Initially these ventures were scattered around the US, with only 1 of the first 69 firms during 1895-1900 located in Detroit. But by 1913 there were 41. In a later study, Klepper [2007] traced the process of spin-offs and the movement of experienced managers from existing firms to new firms. Detroit however had a diverse and large manufacturing base, including rolling stock for railroads, cast iron products such as stoves, shipbuilding for the Great Lakes, and other diverse industries. It was centrally located, and large enough to provide sufficient labor. Other industries, such as the (horsed) carriage makers of Flint (home to Billy Durant), were nearby, and there was a bounteous supply of wood for making car bodies. With the success of Packard and Olds, this base proved larger than in New York City, St. Louis, Chicago, Rochester (NY) or Indianapolis, which were the other five early centers. (This is from Cabral et al. [2013] who revisited the issue to focus on determinants of firm survival.) These all had a broad base, but through chance a couple Detroit-based firms did better, and spin-offs (such as Chrysler) were more numerous and more likely to survive the initial start-up period. The semiconductor industry saw entrants such as Texas Instruments outside of the Bay area, but that developed into Silicon Valley. The same thing happened with autos and Detroit.

Nor is venture capital new. The public, or at least the stock market, believed that cars would be the wave of the future before the rise of the "killer app" of Ford's Model. Entrepreneurs could aim for an IPO at an early stage; Billy Durant was able to scrape together a bunch of such ventures in 1908 to create General Motors, which effectively failed in 1910 and again in 1920 only to rescued by creditors. Investors wanted into the new hot thing – which included the formation of other "general" "American" and "trust" agglomerations such as General Electric (1896), American Sugar (1891) and American Tobacco (1890). Durant and his General Motors were part of a boom of such firms in the years leading up to WWI that found a ready market for their shares, even if there was not much of a market for their products.

In sum, from the perspective of technological innovation, venture capital finance and a geography-based entrepreneurial start-ups culture, Detroit was the Silicon Valley of its era.
