I ported the ISP1362 driver from the Blackfin processor to the Coldfire
processor. Specifically I'm using the MCF5282. Everything works perfectly on
smaller flash drives (128MB and 256MB). In fact, a 2GB flash drive that is
formatted to only 512MB also works perfectly.
A 2GB flash drive formatted for 2GB will cause uClinux to crash usually on a
simple operation such as an ls of the root directory. The device does mount
successfully, but an ls will cause a crash. The crash is unfortunately not
consistent. A variety of different types of failures occur.
The uClinux release being used is built from the Linux 2.6.19-uc1 kernel. I
attempted to use the 20080808 release tonight, but unfortunately there are too
many changes to easily port the ISP1362 driver. So, at the moment, I would
like to attempt to fix the bug rather than move to the newer kernel.
Has this problem already been seen and fixed? I don't mind hunting for it
myself, but I'd prefer to not to waste effort if somebody else has already done
it.
BTW, I'll provide my changes back to the community just as soon as I get it all
working properly.
Thank you,
Bob Amstadt
