[U-Boot] Has anyone gotten the mmc commands to work on the NOVSOMTMi.MX6Q-SL-1-D, on the NOVPEK board by Novtech?
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. 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 MMC_RSP_R1,5,6,7 0x4FD77E14 MMC: sd_send_op_cond CMD_SEND:55 ARG 0x00000000 FLAG 0 MMC_RSP_R1,5,6,7 0x00000002 MMC: sd_send_op_cond err -19 CMD_SEND:0 ARG 0x00000000 FLAG 0 MMC_RSP_NONE CMD_SEND:1 ARG 0x00000000 FLAG 0 MMC_RSP_R3,4 0x00000002 Card did not respond to voltage select!
Any help is much appreciated.
Thanks,
Greg

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

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
