I can live with 2021.07-rc1 right now as it atleast starts as an UEFI payload. But my big issue is that I can't start the kernel with zboot. Full debug build isn't that much more informative either. I was thinking different load offsets, but mine seems pretty much standard, so I don't know. I've played around a bit with configuration on both halves, but it doesn't help. > > Heinrich, do you have any ideas? > >> >> zboot 01080000 - 04000000 319c000 >> Valid Boot Flag >> Magic signature found >> Linux kernel version 5.12.0 (ptxdist@ptxdist) #2 SMP PREEMPT >> 2021-06-01T00:00:00+00:00 >> Building boot_params at 0x00090000 >> Loading bzImage at address 100000 (6516096 bytes) >> Initial RAM disk at linear address 0x04000000, size 52019200 bytes >> Kernel command line: "console=ttyS0,115200 rw quiet" >> Kernel loaded at 00100000, setup_base=00090000 >> >> Starting kernel ... >> >> Any ideas? > > Regards, > Simon >
