I’m having trouble getting a useable Android interface working on my new Zero. The process I’ve followed is below. I’ve recorded logs over the serial interface with PuTTY, but I can’t upload them as I’m a new user 
.
- Start recording serial logs in PuTTY.
- Maskrom mode. Load radxa-zero-erase-mmc.bin
- In U-Boot shell run commands specified in https://wiki.radxa.com/Zero/install/Boot_Troubleshooting :
mmc dev 2 0
mmc erase 0 20000
mmc dev 2 1
mmc erase 0 2000
mmc dev 2 2
mmc erase 0 2000
reset - Following steps in https://wiki.radxa.com/Zero/install/eMMC_Android…
i. In maskrom mode, load bootloader.img
ii. Run flash-all.bat, modified to remove reboot commands, like the Linux version of the script. I was really surprised - it worked this time (unlike the previous 5 attempts). - Reboot into Android (fastboot reboot)
- Device shows an “MBOX” logo (“Make your life colorful”) and stops. Key message in serial logs appears to be:
“vout: aml_tvout_mode_work: monitor_timeout”- Tried connecting a USB hub with mouse/keyboard - no change.
- Unplug and replug USB cable - no change.
- Try a different display (1080p native panel) - no change.
- Serial console / shell is accessible. Caommands can be entered via PuTTY.
- ADB reports a connected device.
I can’t upload the serial terminal logs and I’m not sure of what other kinds of boot messages to look for. Does anyone have any ideas on how to get the launcher displayed?
Edit: I found some video sub-system-related error messages…
