Problem booting HiKey970

I’ve got a HiKey970 board of unknown origin from eBay. No successful booting upon power on. Power LED is ON, SD Card LED briefly goes on, if sdcard is present. CPU copper cover becomes warm after few minutes.

USB-C UART does not show up in any combination of DIP switches. So, I’ve connected 232 USB to UART to the UART6 pins on the 40-pin Low-speed Expansion connector:

On power on, I get the following log:

No further output is coming, only SD Card led briefly blinks afterwards, if sdcard is present.

Could you please kindly help me to figure out how to proceed with the boot?

Thanks,
