Hi Andrey,

thank you for your reply.

I have done as you instructed, but there will be an error message as follows:
============================
Built intel/apollolake_rvp (Apollolake RVP)
E: Image does not contain BPDT!!
E: build/util/cbfstool/ifwitool: ifwi parsing failed
src/soc/intel/apollolake/Makefile.inc:118: recipe for target 'files_added' failed
make: *** [files_added] Error 1
=============================

If I want to build an APL 8MB BIOS need to prepare what the necessary components?

Thanks in advance for your help!!!


Regards,
Morris

Hello,
 
I am building coreboot image for Apollo Lake.
My designed mainboard comes with DDR3L SODIMMs + PMIC.
 
To my knowledge,
RVP1 board is for DDR3L SODIMMs and discrete VRs.
RVP2 board is for LPDDR3 and PMIC.
 
If I selected under coreboot configuration:
Mainboard --> Mainboard vendor (Intel)
                        Mainboard model  (Apollolake DDR3 RVP1)
 
How to modify VR type from Discrete to PMIC???
You need to re-generate IFWI image and the descriptor with Intel-provided FIT tool.
Then you need to reference them with CONFIG_IFWI_FILE_NAME and CONFIG_IFD_BIN_PATH

Best,
Andrey
