DRA821U: EMMC startup issue

Part Number: DRA821U
Other Parts Discussed in Thread: DRA821, CSD

Hi team,

The following issues were observed during patches after EMMC burning:

1) The bin file with uboot cannot be started when finished burning. While the bin file can be started when importing mmcblk0boot0 with dd command.

2) "MMC partconf 0 1 1 1 1 1;MMC bootbus 0 2 0" entering uboot using SD boot mode, this command enables the unbootable hardware to boot.

"MMC partconf 0 1 1 1 1; MMC bootbus 0 2 0 0"

The customer would like to know if this command read or write to some EEPROM registers of DRA821 or EMMC. Could you help check this case? Thanks.

Best Regards,

Cherry
