PinePhone issues

Connecting to UART

Set headphone micorswitch to OFF.

tio /dev/ttyUSB0

Apparently baud of 1500000 should be used but only default works.

Booting from SD
arch=arm
baudrate=115200
board=sunxi
board_name=sunxi
...
bootargs=init=/init.sh rw console=tty0 console=ttyS0,115200 earlycon=uart,mmio32,0x01c28000 panic=10 consoleblank=0 loglevel=1 PMOS_NO_OUTPUT_REDIRECT PMOS_FORCE_PARTITION_RESIZE pmos_boot=/dev/mmcblk0p1 pmos_root=/dev/mmcblk0p2 lima.sched_timeout_ms=2000

So it could be some bootloader setting.

PinePhone audio playback kernel panic

After around 5-6 minutes of mpv mp3 stream playback I get:
