Hi Lei Yu,

After following your instructions, the CONFIG_DEVMEM is still not set in the below '.config'

workspace/sources/linux-aspeed/.config

It did work if I directly modified meta-openbmc-bsp/meta-aspeed/recipes-kernel/linux/linux-aspeed/ast2500/defconfig

Thanks.

OK, you are using devtool. Then the simplest you can do is to reset and
modify the recipe again:

devtool reset linux-aspeed
# Manullay delete the linux-aspeed dir in workspace
devtool modify linux-aspeed
