<div dir="ltr">Hello Alex,<div><br></div><div>Glad if you solved at least initial problem. Glad if I helped at least a pinch. :-)</div><div><br></div><div>Now... As much as I know, FSP is initial part of the BIOS itself, or BIOS elements. Namely, SEC and PEI phases. My best guess is that<b><i><u><font color="#ff0000"> INTEL retained POST codes to be the same as while in (UEFI) BIOS</font></u></i></b>. UEFI in parenthesis, since these two phases are common/default ones, they belong to legacy as well as to UEFI BIOSes. DXE is the phase legacy and UEFI start to diverge (my best guess).</div><div><br></div><div>York can help you more with the POST codes, York should know (much) more than me, considering FSP. Yang, could you, please, come with the FSP POST code table, it will be very beneficial to this community?</div><div><br></div><div>Now, assuming that my initial cludge (in <b><i><u><font color="#ff0000">RED</font></u></i></b>) is correct, you can find the meanings of POST 0x52:</div><div><a href="http://www.congatec.com/fileadmin/user_upload/Documents/Others/AMI_Aptio_4.x_Status_Codes_PUB_01.pdf">http://www.congatec.com/fileadmin/user_upload/Documents/Others/AMI_Aptio_4.x_Status_Codes_PUB_01.pdf</a><br></div><div><br></div><div>PEI Error Codes:</div><div>0x50 Memory initialization error.

<br>
I really appreciate your help. I was able to resolve the problem on late Friday. I cannot exactly tell what the reason was, however, I set up a fresh install of coreboot, just using my old .config and microcode. Then I saw that the board gets past the microcode update. I must have introduced a bug somewhere... sorry, for the noise...<br>
<br>
Now the board stops at TempRamInit in FSP. I'm already using the FSP for Braswell from the Intel link you referenced. The function does not return, but the board shows me post code 0x52. I'm pretty sure the post code comes from FSP because I temporarily redirected all post codes to port 0x84 in the coreboot configuration.<br>
<br>
>From src/drivers/intel/fsp1_1/cache_as_ram.inc I see that TempRamInit gets a pointer to CAR_init_params which is generated from .config. Those values seem okay.<br>
<br>
#define CONFIG_CPU_MICROCODE_CBFS_LOC 0xFFE68400 #define CONFIG_CPU_MICROCODE_CBFS_LEN 0x10C00<br>
#define CONFIG_ROM_SIZE 0x200000<br>
<br>
Has anyone any experiences with FSP post codes? I can't find any documentation about that.<br>
<br>
Thank you,<br>
Alex<br>
