As the APCs are still ‘awaiting customs clearance’, I decided to try to cross-compile the kernel source available at github: https://github.com/apc-io/apc-8750
Unfortunately, many of the APC-specific drivers (‘wmt’) are currently missing.. The system is an Android 2.3 one, and the kernel is based – as you would expect – on Linux kernel version 2.6.32. (In this case – 18.104.22.168).. The U-boot code is also available, and oddly enough, some of the ‘missing’ (video/touchscreen) drivers are available as part of that source tree.. The U-boot code also has missing drivers, so neither the kernel nor U-boot was able to be compiled.. I did find some of what appeared to be the ‘correct’ drivers in the Android code on Google, but most of those were not GPL..
I’m not planning to do any more until the APCs actually arrive, and then I will be checking to see if drivers are available in a later (3.5) version of Linux.. The Raspberry Pi has the same ARM CPU, so it may be possible to do some ‘hacking’ there…
The APC forum has messages indicating various potential projects to port ‘mainstream’ Linux, so maybe some of these will enable the device to be fully supported, and hopefully a working set of APC kernel code will be released, in the near future.. The device has great potential, and it would be a shame to see it crippled by ‘closed’ code..
