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.
