Must follow wiki to change file
linux-2.6.x/arch/blackfin/mach-bf537/boards/stamp.c for testing.
--- angelia wu 2010-11-04 03:07:50
I test it again according to the description as the above, but there is still
the problem.
--- Bob Liu 2010-11-07 21:44:03
The conflict problem has been fixed by commit 9479.
But the spiflash seems still can't work.
--- Bob Liu 2010-11-15 04:38:28
After using the correct cs pin, it works sometime.
I tested the spiflash using "modprobe m25p80; rmmod m25p80".
The first time it can't work but after that it works fine.
--- Bob Liu 2010-11-16 06:06:27
The reason the spiflash can't work at the first time is that there is no sport
clock.
But if don't plug in the spiflash, the sport can provide clock correctly at the
first time modprobe.
