Hi Sameer,

The version of the ME RW binary must match the CONFIG_SOC_INTEL_CSE_RW_VERSION Kconfig value (it's a string).

hi ,
I built a coreboot image for ADL RVP, In that image cse lite cbfs
version is not matching with the cse lite RO and RW version. As a
result, target is updating the CBFS cse lite and rebooting again and
again. Any Thoughts on how to fix this?.

Below is the log
