Hey,
i got a lidar device on uart 2 whch continously sends data, after start up, preventing the boot of the raxda. Can you disable the uart boot loader?
Raxda Zero 3W device on uart prevents boots
With Radxa OS you can’t disable it, but you can set the prompt & timeout to 0, which will allow it to boot while receiving data on UART
Edit /boot/extlinux/extlinux.conf and set both prompt and timeout to 0.
If you run Radxa’s script u-boot-update it’ll set both these values back to the default 1 & 10, even if you update the defaults in /usr/share/u-boot-menu/conf.d/radxa.conf as their is a bug in the script. So remember to edit extlinux.conf if you ever run u-boot-update.
Also remember to turn off UART debug console when booting kernel.
Edit /etc/kernel/cmdline and remove “console=ttyFIQ0,1500000n8“
If you are using Radxa CLI OS, I have a script that will patch the image for you and fix these issues.
