Hi,
while trying latest u-boot GIT on snow (Google Chromebook ARM), I encountered some problems with external SD card. I cannot access to external SD card ('mmc dev 1' just returns 'Card did not respond to voltage select!' and then 'Timeout') whereas I have access to internal eMMC (with 'mmc dev 0').
Did you check SD-card's power and clock line? "Timeout" is not important.
Any idea what could be the problem?
You can enable CONFIG_MMC_TRACE, and you can also print debug message into dw-mmc.c Could you share it?
Best Regards, Jaehoon Chung
On arndale board (same SoC), there is no such SD/MMC problem.
