Jeremy,
It looks like you are loading to 0x4002000000 instead of 0x82000000. MP30-AR0 uses a 2GB base address, thus 0x82000000 is required.
Thanks. That seems to be working this time around.

One thing I did change was to not boot via TFTP since I'd rather not

replaced the load_tianocore variable like so (assuming dev 0, part
1):
setenv load_tianocore 'fatload mmc 0:1 0x82000000
mp30ar0_tianocore_ubt.fd;
fatload mmc 0:1 0x1d000000 mp30ar0_tianocore_sec_ubt.fd'
Is there a reason for your use of '0x82000000' instead of
'0x4002000000'?
'0x82000000' is by default kern_addr_r & kernel_addr_r and looks wrong to me.
I was imitating the values that work for TFTP.
Ah. I spoke too soon. Looks like, with this in place, I make it to to
the
GRUB menu then things get lost from there.
Might there be additional requirements on the SD card?
I wouldn't have thought so. Perhaps your use of '0x82000000' is causing the problem.
I'll give that a go. Thanks.
Hmmm, '0x82000000' seems to get me in a hung state. Output below.
