[U-Boot] Has anyone gotten the mmc commands to work on the NOVSOMTMi.MX6Q-SL-1-D, on the NOVPEK board by Novtech?

[Greg Topmiller]

I am using release 2012.07 of u-boot with board type freescale/mx6qarm2.  The mx6qarm2 is what is used as the board type in the freescale u-boot delivered with the board.  We want to use the main line u-boot 2012.07.  To get it working I had to change the serial port and it boots ok.  I also noticed sdhc1 and sdhc2 were not being initialized with fsl_esdhc_initialize.  I tried to initialize them but it hangs on "mmc rescan".  I turned on CONFIG_MMC_TRACE and get the following.

MX6QARM2 U-Boot > mmc rescan
board_mmc_getcd called for FSL_SDHC
MMC: mmc_set_bus_width
MMC: mmc_set_clock
MMC: mmc_go_idle
CMD_SEND:0
                ARG                      0x00000000
                FLAG                     0
                MMC_RSP_NONE
MMC: mmc_send_if_cond
CMD_SEND:8
                ARG                      0x000001AA
                FLAG                     0

FYI, below is some debug output when sdhc1 and sdhc2 are not initialized and doing an mmc rescan.

Any help is much appreciated.

sdhc1 and sdhc2 are not available on mx6qarm2. Only sdhc3 and sdhc4
you can use on this board.

I would suggest you to double check the iomux settings for sdhc1 on this board.

Also, if you post the changes you did for adding support for the
Novpek board it is easier for us to review and maybe come up with some
ideas.

Is it working now? Would you care to add support for this board in
mainline U-boot?

Yes, it looks good.

Do you supply power to the card ?

Thanks for the response Merek.  I got it working.  I forgot to set the pad setting for the sdhc pins.

Thanks,

Greg
