Actually for i4p all I need is a USB cable since the it includes FTDI converter already, inside the box. The only thing is that I need to setup a laptop sitting next to it so I can connect the cable and then log the output ... The i2u on the other hand doesn't have this (and it doesn't have any thing to connect an external serial probe unless I disassemble the casing, which I'm currently reluctant to do), so it's rather useless for debugging kernel issues. Update on the issue: I've decided to try another path - Russel King the ARM kernel maintainer has updated his cubox-i patches to work with 3.16-rc kernel (so now the cubox-i can run mainline kernel + his 40-odd patches). I have tried building 3.16-rc5 kernel with his patches (using "aufs3.15" branch, since aufs3.x-rcN doesn't work for me) and I still got the same issue so far. If it is a kernel bug when it would be a very subtle one to survive from 3.10.30 to 3.16-rc5, and build a very different configuration. If it is the cubox-i issue (e.g. DMA overwriting part of aufs variables) then I'm really really out of luck here :( But we won't know that until I can get the logging output intact, and I'm still working on it. cheers! -- James B <jamesbond3...@gmail.com> ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
