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,
