Following up on previous email and filling in details: I also get repeated 'C' on the serial console when the sytem tries to boot from EMMC. With 11.2-BETA1 or the older snapshot, this happened even if I held down the boot switch. I think it is from a repeated error that I have also seen along the lines of "Cannot set timing on EMMC" but I can't prove that. But it boots fine from SD card with 11.1, and (fwiw) the EMMC works fine from FreeBSD. I'll file the PR if no one has beaten me to it. Mike
