Based on imx7dsabre board we have design our custom board, the main changes are listed below

Sl No.

Referring to "MX7D_DDR3_register_programming_aid_v1_2" made the changes for DDR3 in uboot. Uboot fails to detect the mmc and thus does not proceed further.

 

MMC: no card present
mmc_init: -123, time 2
mmc_blk_probe: mmc_init() failed (err=-123)
*** Warning - No block device, using default environment
