I did kind of manual bisect by commits to config/boards/odroidm1.conf
U-Boot 2024.04-armbian (Jan 29 2025 - 02:13:41 +0000)
commit 3215bf9f3699c2ee4bc741efe82065315e4ff46f
linux-u-boot-odroidm1-edge_24.8.0-trunk_arm64__2024.04-S2504-P3b44-Haddb-V73be-B4f92-R448a.deb is GOOD,
U-Boot 2024.07-armbian-2024.07-S3f77-P7e9c-Hfb3e-V8f4f-Bb66d-R448a (Jan 29 2025 - 02:30:21 +0000)
commit 268c2e85960978c90025bc18cf7d5f8e5cfbdab6
linux-u-boot-odroidm1-edge_24.8.0-trunk_arm64__2024.07-S3f77-P7e9c-Hfb3e-V8f4f-Bb66d-R448a.deb
is BAD
then I fix my Odroid M1 by doing
sudo apt install ./linux-u-boot-odroidm1-edge_24.8.0-trunk_arm64__2024.04-S2504-P3b44-Haddb-V73be-B4f92-R448a.deb
then
armbian-install → Install/Update the bootloader on MTD Flash
