My denverton system is crashing after the FSM memory init, probably when jumping to POSTCAR. The following lines are shown before the crash:

[DEBUG]  TPM: Digest of `CBFS: fallback/postcar` to PCR 2 logged
[DEBUG]  Loading module at 0x7f7ce000 with entry 0x7f7ce031. filesize: 0x6060 memsize: 0xc358
[DEBUG]  Processing 246 relocs. Offset value of 0x7d7ce000
[DEBUG]  BS: romstage times (exec / console): total (unknown) / 1350 ms

Below are my CAR settings:

# CONFIG_USE_DENVERTON_NS_CAR_NEM_ENHANCED is not set
CONFIG_USE_DENVERTON_NS_FSP_CAR=y
CONFIG_ARCH_POSTCAR_X86_32=y
CONFIG_POSTCAR_STAGE=y
CONFIG_CARDBUS_PLUGIN_SUPPORT=y
CONFIG_FSP_CAR=y
CONFIG_POSTCAR_CONSOLE=y

Everything is fine when using coreboot v4.14.

I have tried using CONFIG_USE_DENVERTON_NS_CAR_NEM_ENHANCED but things got even worse - in this case nothing is shown in the console output.

Any suggestions?

Thanks,
