santo4ul · Posted at 7/30/2019 00:40:04

Hi,

I'm using Android 8.1 on my Firefly RK3399 board.

I'm trying to compile u-boot with DDR @933Mhz.

Could you please share instructions?

Thanks,
San

$ cd u-boot
$ cat ./tools/rk_tools/RKBOOT/RK3399MINIALL.ini
[CHIP_NAME]
NAME=RK330C
[VERSION]
MAJOR=1
MINOR=12
[CODE471_OPTION]
NUM=1
Path1=tools/rk_tools/bin/rk33/rk3399_ddr_800MHz_v1.12.bin

LOADER2=FlashBoot
FlashData=tools/rk_tools/bin/rk33/rk3399_ddr_800MHz_v1.12.bin
FlashBoot=tools/rk_tools/bin/rk33/rk3399_miniloader_v1.12.bin
[OUTPUT]
PATH=rk3399_loader_v1.12.112.bin

Change "rk3399_ddr_800MHz_v1.12.bin" to "rk3399_ddr_933MHz_v1.12.bin".
(check what are available in SDK/u-boot/tools/rk_tools/bin/rk33/)

Not tested. You are on your own. Good luck.
