To give the ROM access to the boot partition, the following commands must be used for the first time:
=> mmc partconf 0 1 1 1
=> mmc bootbus 0 2 0 0
The above command sets up the EXT_CSD register of eMMC flash and enables boot from boot0 partition.
Power the EVM off. Set the boot switches [SW2:SW1] to eMMC boot. When the board is powering on, hit any key to stop u-boot auto-booting. Enter the following u-boot commands. Alternatively, these u-boot commands may also be built into u-boot.
To boot kernel from eMMC, use the following commands after writing rootfs to user partition:
setenv mmcdev 0
setenv bootpart 0
boot
The board should now boot from eMMC with the updated files.
