Hi @Nick A,
I seem to have the same x96q v5.1 board as @Trauma.
He reported some time ago that your x98h image runs as intended on the x96q v5.1 board if the following patch is applied:
https://github.com/sicXnull/armbian-build/blob/333e462466670e9a8609771ccd05977b87800881/patch/u-boot/u-boot-sunxi/board_x96q-v5-1/sunxi_mmc-dec-f_max-to-12MHz-to-get-emmc-reliable.patch
Although the v5.1 image from @sicxnull does work as well including ethernet and wifi, I would also prefer the more recent armbian version.
Can you briefly explain the steps necessary to build a corresponding image for the x96q v5.1?
Thank you
