A191 RV1126 38板通过recovery进行ota升级

SDK版本：RV1126_RV1109_LINUX_SDK_V2.2.5.1_20231011
Nandflash：512MB
该sdk分区规划中默认已经去掉了recovery，修改parameter.txt，修改之后如下：
CMDLINE: mtdparts=rk29xxnand:0x00000800@0x00001000(vnvm),0x00002800@0x00001800(uboot),0x00002000@0x00004000(misc),0x00004000@0x00006000(boot),0x00010000@0x0000A000(recovery),0x0008A800@0x0001A000(rootfs),-@0x000A4800(userdata:grow)
uuid:rootfs=614e0000-0000-4b53-8000-1d28000054a9
增加了misc和recovery分区，编译整包之后烧录，rootfs启动不了，报错如下：

请问有大佬在A191上试过ota升级吗？麻烦帮忙指点一下，谢谢。
