Hi Mark,
> mmc0: error -84 whilst initialising SD card
Not sure how much this'll help, but:
errno -84 is defined in include/asm-generic/errno.h as EILSEQ, and
there are two occurences of EILSEQ in sdhci.c, one of which has a
printk next to it that you aren't seeing. So, it's likely that you're
seeing:
else if (intmask & (SDHCI_INT_CRC | SDHCI_INT_END_BIT | SDHCI_INT_INDEX))
host->cmd->error = -EILSEQ;
So, it seems like your controller is returning a successful command
response, but with some sort of data error attached. Have you tried
multiple SD cards, and are they known-working?
If you're sure it's not the card, try passing debug_quirks=1 to the
sdhci module. (Let me know if you're not sure how to do that.)
Thanks,
- Chris.
