are you changing the board resources at all ?

m25p80: probe of spi0.1 failed with error -22

 

--- Mingquan Pan                                             2011-06-14 23:24:40

I didn't change anything on the board as this board is for regression test in

the lab. The issue should due to source code change.

 

--- Mingquan Pan                                             2011-06-15 01:36:55

The spi-net test running on bf537-stamp regression board also fails to be

detected.
