Building Intel SoC Apollo Lake with DDR3L+PMIC

[morris.wang]

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???

Kind regards,
Morris

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

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
