end of a XO-1

[James Cameron]

Thanks, very interesting.

Quite true that SPI FLASH reprogramming of XO-1 B2 is a challenge.  We
would normally replace the SPI FLASH chip with a freshly programmed
one.

The SCI text you saw was the EC serial port explaining what it was
sending the host over the SCI channel.

I agree it sounds like the EC is now dead, perhaps ESD, or the output
stage of the relevant pin has failed.
