Hi Darren,

Thanks for your reply.

we want to use Ubuntu and Debian of Linux distro.

we have some production used FPGA to make a TDM bus, that
is special designed with 32bits, so, that is why we want try MBM with
32bits UEFI ;)

        Linux with 32bits UEFI

The process would be very similar, the trouble is many common Linux
distributions do not support UEFI boot on 32 bit. Is there a particular
distro you wanted to use? Better question.... Why would you want to run a
32b distro?
