That suggests you're still using an old U-Boot that doesn't initialize
the voltage regulators properly. If you have a bootloader in SPI
flash, you'll have to erase it or disable the SPI clock by connecting
pin 23 and 25 with a jumper wire.

Unfortunately not.

Yes, I have a similar diff. I'll see if I can update the sysuitls/dtb
port.
