MMC may wrongly regconize 2GB eMMC as high capacity
Hi Terry, > So I guess: > mmc_init calls mmc_send_op_cond  that set  high_capacity, > than it calls mmc_startup, that, with MMC_CMD_SEND_CSD  command, set > the capacity, using values in CSD register. > So I guess that mmc_change_freq should not recalculate high_capacity. > > It seems better, isn't it? > > Regards, > Raffaele > Finally I think that it is enough to apply the following patch in order to fix the issue.
