Need a working image for Quartz64B

It looks like my UART instance is not working. I checked all possible combinations of speed parameters, different modules and USB-UART wires (which work fine on all other RK35xx devices, including Quartz64A, SOQuartz). I use contacts to connect 6-8-10. Swapped the RX\TX, tried different GRN connection points on the board itself. But I do not receive absolutely any data to the console, i.e. not a single byte is received (absolute silence, there is not a single "strange" character, as happens when the data transfer rate is not correct) either from the u-boot stage or from the kernel. But there is good news, I picked up a power supply with which the system stably starts and works. Surprisingly, the ancient power supply from the old TV box with 5V\ 1.5A worked. With it, the device began to work without cyclic reboots.

I still need to look further into it, but I had the same issue with a Model-B, no output on both UART adapters (both woodpecker), while both work fine with Model-A.
The Model-B did work fine though (with Plebian), just no output on the serial console.

I haven't tried yet with another power supply, but I think I only have 5V 3A ones.

I bought a power supply and set it to 5V and it only delivers 1A (!). To my surprise, the Model-B did boot up, but there's still 0 output on the serial

Next test will be with a newer Plebian image as I noticed mine was rather 'old' (2022-12-01) and with a custom kernel, whereas it now comes with a Debian kernel.
