- Rock PI 4B+
- Android TV 9.0 build from source code default build AND official Ubuntu release.
I’ve strictly follow the official serial debugging tutorial. However, my minicom stays no output. According to the PC, the pl2303 is properly started.
[ 0.121711] printk: console [tty0] enabled [ 3.746173] tty tty44: hash matches [ 8.123309] usb 1-2: pl2303 converter now attached to ttyUSB0
I’ve seen no message through uboot, kernel, Android. It just remains silent.
