How are you building the kernel?

I strongly recommend you build kernels directly from the kernel source tree rather than using bitbake, if that's what you're doing.

In the kernel source tree, do:

$ export ARCH=arm
$ export CROSS_COMPILE=arm-linux-gnueabi-
$ make aspeed_g5_defconfig
$ make W=1 -j$(nproc)

This exports are from memory, ymmv.

In addition to giving you more output than Greg is after, it has a much lower write/compile/test latency.

Hope that helps,

Andrew
