Hello,
I had my Rockpro64 V2.1 board running fine with Debian bookworm and U-Boot built from sources written to SPI. The board was run only occasionally so did not have a lot of stress so far (I believe less than 100 operating hours total). In normal usage the CPU temperature reported by the internal sensor was around 48°C.
Some days ago I had problems booting: the white led would not come on. I tried shorting 23-25 to bypass SPI and I was able to boot from the SD card I originally used to flash U-Boot. Even if the jumper was removed during boot, trying "sf probe" resulted in an error message saying "unrecognised jedec_spi_nor flash".
After this, every further attempt to reboot to reboot with the same SD card resulted in the following:
In the process above, I realised the heatsink (tall profile type) got very hot (over 80° measured by IR thermometer), even if the case was open and only U-boot was running (actually not doing anything).
I also tried flashing another fresh SD card with Debian bookworm files and booting from it, but the result is the same: no HDMI output, unrecognised SPI, overheating and reboots.
I suspect something has gone wrong with the hardware of the board and there is no chance of salvaging it, but I am trying anyway to ask here for possible further checks. Thanks in advance for any suggestion.
Log from fresh Debian boot attempt (disregard the errors for missing Debian installer files, here I was just trying to bring up U-Boot to the HDMI screen):

After this, every further attempt to reboot to reboot with the same SD card resulted in the following:
- HDMI completely dead
- white led comes on, no matter if the 23-25 jumper is installed or not (seems like the SPI is dead, so it skips to SD anyway)
- U-Boot boots fine as reported by serial terminal
- the following error is reported by U-boot:
Loading Environment from SPIFlash... jedec_spi_nor flash@0: unrecognized JEDEC id bytes: 00, 00, 00*** Warning - spi_flash_probe_bus_cs() failed, using default environment
- after some minutes the board self-reboots
- after this, the board keeps rebooting over and over every few minutes
