MMC not working reliably for Gumstix Overo Tide

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi list,

I've got a Gumstix Overo Tide (OMAP 3530) based board here which doesn't
have NAND and therefore needs the MMC to boot.

I've successfully built a kernel using Tony's master branch. The system
boots fine up to the point where the MMC driver loads (well, I guess
that is where the problem lies). I am using omap2plus_defconfig. The
weird thing is that sometimes the system hangs after printing "Waiting
for root device /dev/mmcblk0p2..." and sometimes after mounting the
rootfs. Any ideas? I've seen some probelms with MMC in the recent past,
could that be the cause?

Thanks in advance.

Cheers,
Andre
