First, the serial ports: The serial console is on the first serial port on the micro-USB connection.
The 0x0000 on the post code display means that it's not actually starting to boot - it's probably hanging in the TXE. There are known issues with upgrading to coreboot from some of the bayleybay roms. I thought Intel was going to document that, but I don't know if they did. The Gold 2 FSP doesn't support D0 parts, so if you have a D0, you need the Gold 3. Also, the FSP is targeted at the embedded sku Baytrail-I. It might work with M/D parts, I haven't tested that. Assuming all that is ok, you probably need to start from a different rom. It might be failing because of the TXE security. You'll probably need to talk to your Intel contact to get that update. Finally, if this is not a personal project, you might be interested in contacting Sage and look at purchasing a BSP to get up and running. Either way, let us know whether you make progress or need more help.
