I'm trying to document the EDK2/GRUB build process but haven't been able to build a working SG2042.fd yet. It builds successfully, but then crashes when I reboot. This is on a Pioneer Box:

If I take SG2042.fd from one of the pre-built Fedora images, it works, so there must be something going wrong in the build. (I am following the steps in envsetup.sh.)

@orlitzky From which distro did you get the already compiled SG2042.fd? Can you give me the link and also the path where it is stored in the archive file?

(I answered on the mailing list, but just in case someone else needs this...)

At the time of writing, the latest SOPHGO Fedora image is,

After decompressing that, you will be left with fedora-sophgo.img, which is a raw disk image (containing multiple partitions) of a Fedora installation. The SG2042.fd file is on the first partition, corresponding to /boot/efi.

On linux, you can use losetup to create loopback devices corresponding to those partitions, and then mount the first one somewhere:

$ losetup -P -f fedora-sophgo.img 
$ mkdir /mnt/fedora-efi
$ mount /dev/loop0p1 /mnt/fedora-efi

Now the file you want should be under /mnt/fedora-efi

@orlitzky I have tried the SG2042.d file from the fedora image which you just provided above and now I am getting following exception during boot.

  • I have copied vmlinuz-6.1.31 from the Fedora distribution to the sd card root directory (it is currently the working kernel)
  • I have copied the the mango-milkv-pioneer.dtb from the installed fedora 38 distribution to the sd card
  • I have changed the grub/grub.cfg just for the menuentry so that it picks /vmlinuz-6.1.31 instead of the gentoo kernel
set default=0
set timeout_style=menu
set timeout=2

set debug="linux,loader,mm"
set term="vt100"
set pager=1

menuentry 'Gentoo 6.1.80+' {
    linux /vmlinuz-6.1.31 root=/dev/nvme0n1p3 rootfstype=ext4 rootwait rw earlycon selinux=0 LANG=en_US.UTF-8 console=tty1
    devicetree /riscv64/mango-milkv-pioneer.dtb

My conf.ini is as follows:

[sophgo-config]

[devicetree]
name = mango-milkv-pioneer.dtb

[kernel]
name = SG2042.fd

[eof]

The directory tree of the SD card is as follows:

.
├── EFI
│   └── BOOT
│       └── BOOTRISCV64.EFI
├── fip.bin
├── grub
│   └── grub.cfg
├── riscv64

│   ├── mango-milkv-pioneer.dtb
│   ├── riscv64_Image
│   └── SG2042.fd
├── vmlinuz-6.1.31
└── zsbl.bin

I am getting following error during boot process (the exception is different from yours, it is EXCEPT_RISCV_STORE_ACCESS_PAGE_FAULT):

Unfortunately these error messages don't mean much to me. I did notice an earlier error in your output,

fdt: failed to add memory node [0, c0000000], error(-2)

that I would be suspicious of. That message is coming from https://github.com/sophgo/zsbl/blob/master/plat/sg2042/boot.c#L617 and the error can be traced back through libfdt. I think it's coming from

offset = fdt_subnode_offset_namelen(fdt, parentoffset, name, namelen);
if (offset >= 0)
        return -FDT_ERR_EXISTS;

because

#define FDT_ERR_EXISTS          2
/* FDT_ERR_EXISTS: Attempted to create a node or property which                                                                
* already exists */

is the error code you see. If it were me, I would try:

to see if that error goes away. But I am 100% guessing.
