Re: [coreboot] coreboot with fsp hangs at post code 19 on Bayley Bay

[Zoran Stojsavljevic]

Hello Kathappan,

I need to look deeper into this area since I am not expert on FSP, but I
have some ideas what could be wrong.

Several questions for you:
[1] Which BYT SoC you are using (example BYT-M N2807)?
[2] How many DDR3 channels (1 or 2) are you using in your design, and what
is the size of memory (most likely not a problem)?
[3] PCH. Do you have PCIe channels initialized/set in default soft straps
(you must have some, at least PCIe root port 0, and PCIe root port 1, as I
recalled)? <<==== IMPORTANT?

Again, I need to think more about this, and I'll try to find some answers,
later... Please, try to see/discover [3] using BCT tool!
