FWIW, I had a cheap board without any power isolation and an SPI chip shared between EC and ME, and supplying power to the in-situ chip was enough to power up EC. That blocked me from doing anything useful. It's still on my pile to attempt to desolder some day and try again! _______________________________________________ flashrom mailing list flashrom@flashrom.org https://mail.coreboot.org/mailman/listinfo/flashrom
