执行到 insmod /lib/modules/4.9.191/xr806.ko 命令时会造成堵塞.

# be the same as the Environment size, which is valid for NOR and SPI-dataflash
# Device offset must be prefixed with 0x to be parsed as a hexadecimal value.

v851s 在分区表中新建分区报错， 主要修改tina-fastboot-v85x/device/config/chips/v851s/configs/fastboot/linux/sys_partition_nor.fex文件。
请问新建分区，除了修改以上文件，还需要修改哪里呢？
