Dear Commutinty,

How can one get debug UART log from Intel FSP for Apollo Lake SoC (e3950 in particular)? There is software requirement in #573449 document (section 4.2.1) that states: "In order to enable the debug message output over serial UART port, the debug version Intel® FSP need to be integrated into the BIOS binary...". I cannot find any reference to debug version of Intel FSP. Intel community forums are useless with such questions.

Do I really need this mysterious debug version of APL Intel FSP binaries or should I just enable debug log in UPD settings of FSP being fetched from git during coreboot build process?

I have a problem passing SiliconInit of FSP-S module. It’s just getting stuck without any error message after invoking FSP-S module. The problem is in UPD settings for FSP-S, I just want to know where exactly.

Best Regards,

Anatolii Vorobev
