BPI-R4 fails to build, missing bl2 firmware

[tabrisnet]

[|] Error 1 occurred in main shell [ at /armbian/.tmp/work-5d76f14c-45ca-4630-ba99-8ded11db4ca4/uboot-write-Fhg7X/usr/lib/u-boot/platform_install.sh:6

 

and tracking down that platform_install.sh yields

dd if="$SRC"/cache/sources/arm-trusted-firmware/mtksoc-20250212/build/mt7988/release/bl2.img of=$2 bs=512 seek=34 status=noxfer > /dev/null 2>&1;

Note that cache/sources/arm-trusted-firmware does not appear to exist, and [although this may be my lack of knowing what to look for] I find no evidence it attempted to fetch this repo or build the firmware.

Yes, this board is only recently submitted, so some problems may be expected. I did wait for the automated build, but no luck there.

or maybe I'm screwing up the build somehow. Using docker, but it's on a Debian11 host, which I know isn't supported as a build platform.

./compile.sh build BOARD=bananapir4 BUILD_MINIMAL=yes RELEASE=bookworm DEBUG=yes KERNEL_CONFIGURE=no BRANCH=current

@chainsx looks to be the guy who submitted the pull-request.

for more fun... the bootloader doesn't appear to build. I tried both the mtksoc-20250212 and mtksoc-20250711 branches.

root@c4b6c21f3c6a:/armbian/cache/sources/arm-trusted-firmware/mtksoc-20250212# make PLAT=mt7988
Building mt7988
  CC      plat/mediatek/mt7988/bl2/bl2_plat_init.c

   10 | #include <bl2_plat_setup.h>

 

There *is* a bl2_plat_setup.h, but it's not in the mediatek/mt7988 dir but rather mediatek/apsoc_common/bl2.

Fixing mediatek/platform.mk to reference that eventually produces a *new* build error

two patches make the build problems go away... plus have to specify BOOT_DEVICE=sdmmc on the make cmdline

Note that I'm *NOT* claiming this will work. Just that the bootloader *builds* with

 make PLAT=mt7988 BOOT_DEVICE=sdmmc

Further, this is me building from inside the docker-shell, it's not doing this for me...
