UUU烧录EMMC分区问题

https://github.com/NXPmicro/mfgtools/releases/download/uuu_1.2.135/UUU.pdf

参考这个脚本kernel_emmc.uuu

ucmd <any uboot command>

也就是说ucmd后面跟uboot支持的命令

FBK: ucmd mmc=`cat /tmp/mmcdev`; PARTSTR=$'10M,500M,0c\n600M,,83\n'; echo "$PARTSTR" | sfdisk --force /dev/mmcblk${mmc}

上面就是通过sfdisk进行分区的操作。

下面是参考脚本

uuu_version 1.2.39
