Hello.
So, I am currently trying to run my favourite operating system
on my shiny new BananaPI BPI-R3. Thus far, I was able to Frankenstein
a u-boot image with the miniroot75.img and got into the OpenBSD
bootloader.
However, whilst loading the bsd.rd MIGHT work, running it does not.
(Please see the .txt file I attached to this email for a full log of the
boot process. It is completely stuck after that last line)
One of my assumptions is that the bootloader itself might load the
bsd.rd to the wrong location in memory, namely the one defined in
/usr/src/sys/arch/arm64/conf/RAMDISK:
makeoptions KERNEL_BASE_PHYS="0x00200000"
makeoptions KERNEL_BASE_VIRT="0xffffff8000200000"
Loading anything to this address on this platform is forbidden:
BPI-R3> fatload mmc 0:5 0x00200000 /efi/boot/bootaa64.efi
** Reading file would overwrite reserved memory **
So my question (to eliminate this hypothesis), can you tell me
if the boot loader is loading the kernel to KERNEL_BASE_PHYS
or KERNEL_BASE_VIRT?
Can I solve this issue without having to recompile the kernel?
