Booting on Nanopi M4 shows an error...

[RicStrang]

Hi,
I have the original Nanopi M4 and can't get it to boot using your Ubuntu Jammy or Luna images...

Booting using - wget https://dl.sd-card-images.johang.se/boots/2023-09-01/boot-nanopi_m4.bin.gz
and - wget https://dl.sd-card-images.johang.se/debians/2023-09-11/ubuntu-lunar-arm64-ochei7.bin.gz

Shows this error:
U-Boot TPL 2023.07-rc6-dirty (Sep 01 2023 - 00:06:59)
sdram_init: LPDDR3 - 933MHz failed!
rk3399_dmc_init DRAM init failed -22
Missing DTB

Seems to suggest this boot image is for Nanopi RC6?

Thanks

Richard

Trying again using the m4b boot image works on an original Mk1 Nanopi M4:

wget https://dl.sd-card-images.johang.se/boots/2023-09-01/boot-nanopi_m4b.bin.gz
