Hi,
this commit is breaking MMC support on Nokia N900:
a7778f8fbee098c78b1fa1e1331313a7e217fb30 omap_hsmmc: Wait for CMDI to be
clear
I'm geting only error message "timedout waiting on cmd inhibit to clear"
and I cannot read files from eMMC and SD card. When I reverted commit
that commit I all is OK.
OK, we need to debug what the n900 is doing (do you see this in qemu,
real HW or both?) since clearing the bit fixes certain SD cards on
other boards (beagleboard and gumstix iirc, but it was a generic
issue). Thanks!
RX-51 build of U-Boot in qemu cannot read mmc. It report error about bad
voltage. This was problem also before that commit. RX-51 Linux kernel does not
have any problem with mmc, special prepaired Maemo 5 image (with some SW on
eMMC) from Nokia working fine in qemu.
I ignored above problem in qemu, because mmc worked fine on real n900. But
after that commit mmc does not working on real n900 too.
First, if you change SD cards, does the problem go away? Second, my
expectation is that we will make further changes, probably not in time
for v2012.03, to the omap_hsmmc.c driver to bring it more in-line with
how the kernel driver works. Thanks!
