I figure I'd make this a new post. Thanks to @Markus_ and @Igor for their help. I'm still trying to get wifi module 3 working, but I'm happy to at least have an up to date C1 image.
git clone --depth=1 --branch=master https://github.com/armbian/build
cd build
mkdir -p ./output/debs
wget -c -O ./output/debs/linux-u-boot-current-odroidc1_23.02.0-trunk_armhf.deb http://apt.armbian.com/pool/main/l/linux-u-boot-odroidc1-current/linux-u-boot-current-odroidc1_21.02.3_armhf.deb
./compile.sh CLEAN_LEVEL= BOARD=odroidc1 BRANCH=current RELEASE=jammy REPOSITORY_INSTALL= BUILD_MINIMAL=no BUILD_DESKTOP=no KERNEL_CONFIGURE=no KERNEL_ONLY=no COMPRESS_OUTPUTIMAGE=sha,gpg,img
ls ./output/images
u-boot has not been able to be built for a while now (last supported image was focal and 5.x kernel).
Step 4 copies the last good u-boot to ./output/debs which is created in step 3. Change current in ./output/debs/linux-u-boot-current-odroidc1_23.02.0-trunk_armhf.deb to edge to use edge kernel. Also change build number 23.02.0 to current build number.
Step 5 does build without prompting. Change BRANCH=current to BRANCH=edge to build edge branch. If all goes well you should see image with step 6.
Issues:
reboot not working.
Headless, no HDMI.
No wifi at this point, just wired.
Current branch with 5.x kernel corrupts SD. I found this build totally unusable.
