Hi All,
I just received 3 Rock Pi S and I can’t make any of them boot !!!
It’s the D version (minimal config) without NAND, Radio,…
I tried with official image, with armbian image, with ubuntu image, with different power supply, with different USB-C to A cables, with 3 different SD.
In the best case with the official image I got the following message from the console:
DDR Version V1.26
Only one line on the console port nothing else…
Anyone can help ?
Please try this image: https://dl.radxa.com/rockpis/images/ubuntu/rockpi-s-ubuntu-focal-server-arm64-20220308-0852-gpt.img.xz
Hello, this image works but could you provide more information about the changes needed?
Is it a fix on bootloader?
Thanks
Can you provide a picture of the board? We have had a very small batch of chips replaced recently, I can confirm that.
The RK3308 in 2022 is now manufactured in SMIC, it’s call RK3308 S version. The bootloader and version should be updated to support the S version(lower core voltage). See the detailed changes here:
Hi,
Yes, i can provide 
Front:
Back:
We are having hard time to buy around 500 units, Could you help us or give more information?
Thanks
Hi Jack,
Thanks for information, where or when can i find the official versions to RK3308B-S (U-Boot)?
We have a custom image to RK3308 based in DEBIAN and we want to fix it to run in these new boards.
Its my eyes @setq old and misleading its a 3308b so you have a mixture at the moment
That one seems to be running at the full new speed of

1296000

The info I guess is in 4.1 The rkbin Software Repository Update Confirmation
Where
In order to be compatible with the RK3308B-S&RK3308H-S chip, the following important Binary files must be updated and
double check the requirement version.

@setq Actually its running on the old opp table

Guess that is why it keeps throttling even though temps don’t seem that high.

The bs opp table is there with rk3308bs-cpu0-opp-table naming but the old opp table is still being used.
I have never seen this sort of layout with 2x opp table and are we supposed to manually edit the dtb (dts) ?

Oh I just purchased and had to get my magnifying glass out but got a rk3308b not rk3308bs so seems you have a mixture.
