Linux: How to flash the eMMC on Beaglebone Black

Hi ,
I am working follow an example as e2e.ti.com/.../1204926 page from Miroslav that is worked well.


Run the BBB from the SD card (hold the USR button when powering the board up)

3. ssh into the board:
# ssh root@172.20.0.111

4. The eMMC is /dev/mmcblk1. Format it this way:
4.01. fdisk /dev/mmcblk1
4.02. o - this clears the existing partitions
4.03. p - this lists all partition tables on the card (there should be none)
4.04. n - create a new partition
4.05. p - primary partition
4.06. 1 - partition number
4.07. 2048 - default value for the first sector
4.08. +16M - last sector / partition size
4.09. t - change the partition type (select partition 1)
4.10. e - change tha partition type to "W95 FAT16 (LBA)"
4.11. a - set the bootable flag for the selected partition (1)
4.12. n - create a new partition
4.13. p - primary partition
4.14. 2 - partition number
4.15. hit Enter to choose the default (next available) value for the first sector
4.16. hit Enter to choose the default (last) value for the last sector
4.17. p - this lists all partition tables on the card (there should be two)
4.18. w - write all the above changes to disk
4.19. umount /dev/mmcblk1p1; mkfs.vfat -F 16 /dev/mmcblk1p1 - format the first partition
4.20. umount /dev/mmcblk1p2; mkfs.ext4 /dev/mmcblk1p2 - format the second partition

5. Copy the {MLO,u-boot.img,uEnv.txt} files to the first partition:
# mkdir boot
# mount /dev/mmcblk1p1 boot
# cp {MLO,u-boot.img,uEnv.txt} boot
# umount boot

6. Copy the root file system to the second partition:
# mkdir root
# mount /dev/mmcblk1p2 root
# tar -xf tisdk-rootfs-image-am335x-evm.tar.gz -C root
# umount root

7. Shutdown the BBB, remove the SD card and start it from the eMMC.
