Hi,
I'm trying to build an image for a NanoPi-M4 but it is not able to get out of TPL. The U-Boot build seems to be constructing the idbloader.img properly, but the board is failing to boot. Note that this is an original NanoPi-M4 (i.e. V1) and not the NanoPi-M4V2.
From the build log: ... cat tpl/u-boot-tpl-nodtb.bin tpl/u-boot-tpl.dtb > tpl/u-boot-tpl-dtb.bin cp tpl/u-boot-tpl-dtb.bin tpl/u-boot-tpl.bin ./tools/mkimage -n "rk3399" -T rksd -d tpl/u-boot-tpl.bin tpl/u-boot-tpl-rockchip.bin ... cat spl/u-boot-spl-nodtb.bin spl/u-boot-spl.dtb > spl/u-boot-spl-dtb.bin cp spl/u-boot-spl-dtb.bin spl/u-boot-spl.bin cat tpl/u-boot-tpl-rockchip.bin spl/u-boot-spl.bin > idbloader.img
What I get on the console is:
U-Boot TPL 2020.04-rc2 (Feb 15 2020 - 05:36:59) sdram_init: LPDDR3 - 933MHz failed! rk3399_dmc_init DRAM init failed -22 Missing DTB
It's strange that it says the DTB is missing clearly shows the DTB versions of TPL and SPL being used to create the idbloader.img.
In any case, is anyone building and booting U-Boot master for NanoPi-M4?
