E3825 stuck in FspInitApi() Memory Init

Hi Community,

I'm trying to port coreboot to a Intel Atom E3800 Board.

Kontron COMe-mBT10 (https://www.kontron.de/products/boards-and-standard-form-factors/com-express/com-express-mini/come-mbt10.html )

But I'm stuck in FspInitApi probably during the memory initalization.

The last post_code i get from coreboot is 0x92 that i can find in src/drivers/intel/fsp1_0/fsp_util.c just before

post_code(POST_FSP_MEMORY_INIT);

FspInitApi(&FspInitParams);

than some more post codes are send  0x32c 0x22d 0x32d 0x62d 0x22e 0x62e 0x52eb and last one ist 0x12f

after that i'm stuck. FspInitApi is supposed to return to ChipsetFspReturnPoint(EFI_STATUS Status, VOID *HobListPtr) in src/soc/intel/fsp_baytrail/fsp/chipset_fsp_util.c but it never reaches that point.

can someone tell me what these last 3-digits Post Codes mean ?

Thanks

Michael
