I am trying to create a new uSD for the MQ-QUAD and am having issues doing so. I am not comfortable using the web sites (baidu.com) that are written in Chinese graphics as I do not understand them and Google fails to translate.
I have 2 images:
Orangepizero2_3.0.6_debian_bullseye_desktop_xfce_linux5.16.17.img
Orangepizero2_3.0.6_debian_bullseye_server_linux5.16.17.img
I have used both the Pi imager and Balena to try to get these onto a fresh SD card and get the fillowing errors when attempting to boot. These error messages repeat.
U-Boot SPL 2021.10-orangepi (Aug 09 2022 - 21:00:00 +0800)

My older boot SD does boot, but I cannot recall how it was built. It is currently running 3.0.8. The current Debian Bookworm image does not boot, but this one works:
The only image I was actually able to download from this site was the buster XFCE image, and it is relatively huge. I said in my post that I wanted to use a minimal image.
Since that image boots an ARMbian OrangePi release, I figured nothing ventured, nothing lost, and tried booting an image that works on an OrangePi Zero equivalent of the MangoPi board. It fails in the bootloader complaining about a memory controller (as I noted).
So to answer your question, I couldn’t get anything from the Baidu site, but I did get the “bloatware” XFCE desktop image from the Google site. It boots and then it is quite easy to shut down the stuff you don’t need. I want to see what happens if you try to graft the bootloader onto an OrangePi bookworm release but was hoping beyond hope to get some support from MangoPi as to whether or not this is a feasible solution.
As an FYI, I just took the only available image and upgraded to bookworm online. It came down off the site as 1506-nogpu.img.gz and appears to be working, but it is 1.5G so it is a bit bloated. I upgraded as follows:
bracka@MangoPi:~$ free -h
total used free shared buff/cache available
Mem: 983Mi 502Mi 190Mi 3.0Mi 368Mi 481Mi
Swap: 491Mi 14Mi 477Mi
In the vi session, I replaced all occurrences of ‘bullseye’ with ‘bookworm’. Again, it all seems to be working. The next project is to get a minimal image of ‘bookworm’ built or booting. If anybody can point me at an notes on how to set this up for something like ARMbian it would be great. This has been the bloated version of Debian that was provided, … hey, at least it works!
Forgot to mention. In order to do all of this, I have connected a UART to the serial port so that I don’t get trashed when SSH gets updated. I happened to have used a PiUART, but any others will work too.
