Re: [U-Boot] [PATCH] i.MX28: Lower the amount of blocks transfered in one DMA cycle

Dear Fabio Estevam,

Hi Marek,

Some MMC cards, like my ancient 32.0MB SanDisk RS-MMC cards had issue if b_max was set to 0x40 and DMA was enabled. Lower this value to 0x20, which allows these cards to work too.

I know this is off topic here, but I am wondering whether the mxs mmc driver in the kernel is able to handle this card correctly or not.

Linux does, but I think there must be some limit to multiblock transfers there, otherwise it'd fail too.
