Build errors

[Siecje]

After cloning and running ./build.sh I get these errors.

scriptexecutor$ ./build.sh

Build complete. Files are in output folder.

I'm trying to customize the environment and add cryptsetup to be able to encrypt the filesystem.

This particular problem can be fixed by backporting https://gitlab.com/buildroot.org/buildroot/-/commit/9e2128bf5072e5f2fd69e2fc0239558782dfc677

But then at least on my build host I pretty much immediately run into more build failures (building host-m4), I guess it's time to upgrade the copy of buildroot for this project so it's buildable on modern systems again.

I was able to build scriptexecute.img.

git clone https://github.com/raspberrypi/scriptexecutor
cd scriptexecutor
git clone https://github.com/buildroot/buildroot.git
cd buildroot
git checkout 2023.11.1
cd ..
mv buildroot buildroot-2023.11.1
# modify build.sh to contain "buildroot-2023.11.1"
make -C buildroot-2023.11.1 menuconfig
# It said to save to auto apply config migrations
# I saved in the curses interface
# make -C buildroot-2023.11.1 savedefconfig # failed
make -C buildroot-2023.11.1 menuconfig
# remove legacy config option
# in my case add cryptsetup (target packages -> hardware handling -> cryptsetup)
# BR2_PACKAGE_CURL was the only one
# The BR2_PACKAGE_CURL config symbol was renamed to BR2_PACKAGE_LIBCURL_CURL
# save in interface
make -C buildroot-2023.11.1 savedefconfig
./build.sh
# which failed a couple times and based on the errors I did
cp output/config.txt buildroot-2023.11.1/package/rpi-firmware/
cp output/cmdline.txt buildroot-2023.11.1/package/rpi-firmware/
./build.sh
# output/scriptexecute.img was created

When this is updated the firmware should also be updated.

$ vcmailbox 0x0000001 4 4 0
0x0000001c 0x80000000 0x00000001 0x00000004 0x80000004 0x623c6fde 0x00000000 

The current version doesn't support the device private key OTP.

When I would run rpi-otp-private-key[1] I would get "Failed to read the current key from OTP"

I replaced start4.elf and fixup4.dat from https://github.com/raspberrypi/firmware/tree/master/boot

1: I added rpi-otp-private-key as an overlay file in the build (scriptexecutor/buildroot-2023.11.1/board/raspberrypicm4io-64/overlay/usr/bin/rpi-otp-private-key)

It would be nice if this could be updated, there are utils in that buildroot version that give problems with the current images generated with pigen
