Hi Jaap,
Thanks for that. It does seem to be a stack problem. Rather than recompiling the FC3 kernel to not use 4KSTACKS I looked at the cx25840-driver code and it does use a lot of stack for the i2c sequencing. I made a couple of those on-stack arrays into statics and it gets a lot further. So I think I'll spend a bit more time with that code see if I can get it to work all the way. Thanks, Jelte.
