I have been searching for an industrial version of the Beaglebone Black in order to leverage the great know-how and resources available on this great open source hardware platform to make it work reliably on … Read more
I was recently getting Data Aborts on an ARM11 program that makes intensive use on unaligned data accesses. The issue was caused by unaligned floating point accesses, which were not handled by the Linux kernel. Some background on the problem follows. ARM unaligned data access hardware support ARM 32-bit instructions must always be word boundary … Read more
Linux usage is growing enormously in embedded systems, thanks to its stability, being open source, the availability of drivers for a huge amount of hardware peripherals and its support for many networking protocols and filesystems. However, Linux exhibits some drawbacks in safety systems, where the code needs to be certified, or hard real-time systems where … Read more

So far, so good. … Read more
