Troubleshooting ROCKPro64 - alephnull - 03-01-2021

I recently bought a 4GB ROCKPro64 (including power supply) and am unable to make it boot. I have a serial adapter (running at 1500000bps) connected and have tried the following: There is no output following the output messages listed above and the board is not responsive to serial input.  I have tried 2 different SD cards (SanDisk Ultra 16GB A1) and in all cases, verified the data written to the card against the original image file.

Based on RockPro64 boot sequence, the "U-Boot TPL" lines suggest that the TPL is loading but the lack of a subsequent "U-Boot SPL" line suggests that the subsequent SPL loader is not starting.  The ayufan boot prompts are different but I'd expect something similar to my Rock64, which starts:
DDR version 1.13 20180428
ID:0x805 Y
In
SRX
LPDDR3
786MHz

I have tried raising a support ticket but, after more than a month, that has gone nowhere - the only suggestions have been to run a memory test, without actually providing any suggestion as to where I might find a memory test that doesn't require a fully functional U-Boot.  Can anyone here suggest additional troubleshooting steps I can perform?

Hi, you eventually could try to erase the spi and flash it again (https://github.com/sigmaris/u-boot/wiki/Flashing-U-Boot-to-SPI)

I reproduce the same behaviour when the RXD (white wire) is connected (see https://forum.pine64.org/showthread.php?tid=6387). Try to disconnect this wire and reconnect it after the boot.

Thanks for that.  I can confirm that if I disconnect the RXD until after U-Boot starts then everything works.  That's a particularly nasty bug in the boot ROM but I think I can work around it (once configured, I won't have ready access so manually connecting wires isn't possible).
