Subject: [U-Boot] Bisected "sdhci_transfer_data: Error detected in status(0x208002)!" problem on ODROID-X
Date: Tue, 20 Oct 2015 04:57:02 +0300 [thread overview]
Message-ID: <20151020045703.6a452396@i7> (raw)
Hello,
Currently SD card support seems to be broken at least on the ODROID-X
board in U-Boot v2015.10. Checking older U-Boot releases shows that
it used to work in v2014.10, and bisecting points to the commit
a276172cf32386c211c75638f6bf3c0d59ba03ba ("arm: exynos: fix the
div value for set_mmc_clk"):
http://git.denx.de/?p=u-boot.git;a=commitdiff;h=a276172cf32386c211c75638f6bf3c0d59ba03ba
Reverting this commit resolves the problem and the SD card starts
working properly.
As an extra test, I also tried to add debugging print at the end of the
exynos4_set_mmc_clk() function, so that it calls exynos4_get_mmc_clk()
with the original 'dev_index' and reports the resulting mmc clock
speed. After reverting the patch, the reported value is 50MHz. Before
reverting it, the reported value was 100MHz. This is a Transcend
class 6 SDHC card.
Is this enough information or should I check something else?
