SDIO card with parallel NOR

Hello,

we using the experimenter board from logicPD and trying to use the parallel NOR and additional SDIO CARD. do you know if it is possible to use them in parallel since we saw few indications that the MMC/SDIO is shared with the EMIF interface used for NOR. can you please send some links to where I can find linux kernel configuration to support SDIO + parallel nor

Thanks,

    Eilon,

    The only MMCSD pins that are pinmuxed with the AEMIF Bus is the MMCSD0 set of signals CLK/CMD/D[7:0] so if this is the SDIO port being used in the Logic PD experimenter board then you have a conflict with the upper EMA_A[23:14] address lines and your NOR support for addresses >a14 Will be impacted.  Depending on the # of SDIO datalines you need, you can gain a few additional Address lines if you you use less MMCSD datalines.

    I'm not aware if there is any driver in the linux kernel configuration for this I will move this post to where the right audience in the Linux Team might be able to comment.

    regards,

    miguel
