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.
