Thanks for providing those images but unfortunately at least server-lichee_rv_dock fails to boot properly (kernel panic log below).
Also, from the full log it appears that boot0 is used as SPL. boot0 can be fully omitted when using latest OpenSBI v1.2 (upgrade from OpenSBI v1.0-104-ge6793dc).
Good reference about latest versions and image layout can be found from buildroot (I'm not allowed to post full urls)
- buildroot/tree/configs/sipeed_lichee_rv_dock_defconfig
- buildroot/tree/board/sipeed/lichee_rv_dock/genimage.cfg

Best regards,
Indrek

you can try to change to a more detailed conclusion in /boot/uEnv.txt verbosity=4 -> verbosity=8

Hi! Thanks for the new version!
I tried to boot slarm64-current-riscv64-core-lichee_rv_dock-6.1.12-build-20230219.img.zst on my Lichee RV dock and it ends with the kernel panic.
I grabbed some lines from serial console output, with comments:

[27]HELLO! BOOT0 is starting! <----------------- boot0 is obsolete for newer u-boot, you can easily just drop it
[30]BOOT0 commit : d21a737
...
OpenSBI v1.0-265-gc8ea836 <---------------- upgrade from version v1.0 to v1.2
...
U-Boot 2022.01-sun20iw1p1 (Feb 19 2023 - 05:45:24 +0200) <--------- upgrade from 2022.01 to 2022.10
...
Starting kernel ...

[ 0.000000] INITRD: 0x49a0b000+0x005f5000 is not a memory region - disabling initrd <-------- could it be that its beyond the 512MB RAM limit?
[ 0.000000] Unable to handle kernel paging request at virtual address ffffffd801874af0
[ 0.000000] Oops [#1]
...

You could share your boot log if you have one.

Another image I'm working with boots correctly with newer u-boot/opensbi (not related to the slarm64):
U-Boot SPL 2022.10 (Feb 20 2023 - 14:30:14 +0200)
...
OpenSBI v1.2
...
U-Boot 2022.10 (Feb 20 2023 - 14:30:14 +0200) Allwinner Technology
...


Best regards,
Indrek

Hi ikruusa,

I don't have Lichee Rv Dock D1, only Nezha


u-boot memory settings:
Code:
/ {
        // FIXME: this is temporary.
        memory {
                device_type = "memory";
                //reg = <0x40000000 0x80000000>; /* 2 GB */
                //reg = <0x40000000 0x40000000>; /* 1 GB */
                reg = <0x40000000 0x20000000>; /* 512 MB */
        };
};
in the first log with U-Boot 2022.01-sun20iw1p1, the loading goes to the kernel and breaks there, it seems due to the fact that the memory size is not strictly specified in dts.

for test in file /boot/uEnv.txt replace
fdtfile=allwinner/sun20i-d1-lichee-rv-dock.dtb
with
fdtfile=allwinner/sun20i-d1-nezha-512m.dtb

Yes, with fdtfile=allwinner/sun20i-d1-nezha-512m.dtb Lichee RV dock boots and I can log in (tested with core image).

This time I run slarm64-current-riscv64-xfce-lichee_rv_dock-6.1.13-build-20230223.img.zst and it boots without the problem on Lichee RV dock. Although it takes ca. 4 minutes to boot into graphical env, so its a bit overkill for this board. But it works. Thanks!
