I have same issue on Armbian_24.8.1_Odroidn2_bookworm_current_6.6.47_minimal When usb-hdd is connected odroid cannot boot. Odroid spins hdd than restarts.

Max theoretical esp32 chip UART speed is 5Mbps, but nobody can reach this speed - max "config speed" is 921600 and even on 460800 you can get garbage and data loss 😞 For RockPi you need 1.5Mbps. I don't know why Radxa need such speed, may be they think "fast is better" I use BeagleBone single board computer for connecting to my RockPi3A (because HDMI not working in modern kernels), and it is working perfectly. BeagleBone has fastest UARTs avaliable in pocket size

Interesting, do you mean radxa makes own "unofficial" Armbian images?

I tried to install Armbian_22.11.0-trunk_Rockpi-4b_bullseye_current_5.15.76_minimal.img.xz from https://github.com/radxa-build/rock-pi-4b/releases/tag/20221101-0235 After first reboot main partition goes readonly. Checking disk show free cluster records mismatch. It is not SD-card issue, because Ubuntu Server on same SD-card working perfectly.
