I tested with the same configure, but I cannot reproduce.

 

--- Vivi Li                                                  2009-07-24 00:23:03

It can work with board version is 1.2. Board version 1.1 can't work.

 

--- Yi Li                                                    2009-07-24 04:28:19

After more tests, it turns out that this is not related with board revision.

 

The cause is that, there is an ad1836 board and a spi-mmc board on the same

BF533-STAMP. Even if we disable ad1836 support in the kernel, spi-mmc cannot

work if ad1836 board connected to stamp. I did not see this problem on

BF537-STAMP. So there may be some HW issue.

 

 

--- Sonic Zhang                                              2010-09-16 04:48:10

Don't put ad1836 addon and spi-mmc addon to the same bf533-stamp.
