I used L3.14.28 and u-boot-2014 to start my imx6s board, I selected the eMMC as the boot rom.
In mfg tool's config file uc12.xml , I see the uboot section is :
/dev/mmcblk$mmcboot0 bs=512 seek=2
Then on my board, I see the block device view is:
root@imx6qsabresd:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mmcblk3rpmb 179:24 0 4M 0 disk
mmcblk3boot0 179:8 0 16M 1 disk
mmcblk3boot1 179:16 0 16M 1 disk
mmcblk3 179:0 0 7.1G 0 disk
|-mmcblk3p1 179:1 0 500M 0 part /run/media/mmcblk3p1
`-mmcblk3p2 179:2 0 6.5G 0 part /
By referring to the uc12.xml, I can burn uboot via linux command:
echo 0 > /sys/block/mmcblk3boot0/force_ro
dd if=$FILE of=/dev/mmcblk3boot0 bs=512 seek=2
echo 1 > /sys/block/mmcblk3boot0/force_ro
echo 8 > /sys/block/mmcblk3/device/boot_config
But what is the mmcblk3boot1, mmcblk3rpmb section mean?
How the find them in the yocto source code, or in the mfg config file?
