--- Comment #43 from Neal Frager <neal.frager at amd dot com> ---
Unfortunately, when I switch from

this config:
https://gitlab.com/buildroot.org/buildroot/-/blob/master/board/qemu/microblazeel-mmu/linux.config

to this config:
https://github.com/numato/samplecode/blob/master/FPGA/MimasA7Mini/MimasA7MiniLinux-BSP/mimasa7mini_defconfig

The boot does not even start with the qemu.

output/host/bin/qemu-system-microblazeel -M petalogix-s3adsp1800 -kernel
output/images/linux.bin -serial stdio
VNC server running on 127.0.0.1:5900


But I am still thinking the most likely issue is a Linux config option that
enables something which is not covered by Gopi's patch.  Hopefully we can
figure out how to duplicate the failure with the qemu, so that Gopi can easily
work on it.

Otherwise, can your bitstream run on an Artix-7 AC701 board?
