Re: [Buildroot] [Help] How to bump a package, e.g., OpenSBI?

Hello Julien, hello Mark, hello Alistair,

Mark and Alistair, I added you, because you are listed in the DEVELOPERS file 
for qemu_riscv64_virt_defconfig / OpenSBI - hope its ok ;)

Thanks Julien! I locally adjusted the OpenSBI version number and the package's 
hash. Then I adjusted the used version of OpenSBI in the 
qemu_riscv64_virt_defconfig and started a build: The build was successfull, 
hence also the build of OpenSBI v1.6 worked. However, when I try to run 
output/images/start_qemu.sh I get the error, that ROM regions do overlap:

The following two regions overlap (in the memory address space):
  fw_jump.elf ELF program header segment 1 (addresses 0x0000000000000000 - 
0x00000000000271e0)
  mrom.reset (addresses 0x0000000000001000 - 0x0000000000001028)

I guess, that the OpenSBI image had a different starting address in the past, 
leaving some space for mrom.reset? I double checked, and when building 
qemu_riscv64_virt_defconfig without modifying its OpenSBI version, it still 
works, so the problem must come from my changes. I am not so familiar with 
OpenSBI and also not with Qemu and hence was not able to find a solution to the 
problem yet.

I also tried building qemu_riscv64_virt_efi_defconfig, but that board seems to 
need a github login to fetch some package. I didn't look into this in much 
detail yet (e.g., whether it was my fault for some reason), but I am planning 
to have another look at that and then maybe sent a separate email for this 
issue.

Thanks and best regards,
Kilian
