Hi,
i try to use my orange pi one armbian to do uart debug on orange pi 2g iot. I use uart3 on orange pi one and my configuration

  1. [uart0]
  2. uart_used = 0
  3. uart_port = 0
  4. uart_type = 2
  5. uart_tx = port:PA04<2><1><default><default>
  6. uart_rx = port:PA05<2><1><default><default>

  7. [uart1]
  8. uart_used = 0
  9. uart_port = 1
  10. uart_type = 4
  11. uart_tx = port:PG06<2><1><default><default>
  12. uart_rx = port:PG07<2><1><default><default>
  13. uart_rts = port:PG08<2><1><default><default>
  14. uart_cts = port:PG09<2><1><default><default>

  15. [uart2]
  16. uart_used = 0
  17. uart_port = 2
  18. uart_type = 4
  19. uart_tx = port:PA00<2><1><default><default>
  20. uart_rx = port:PA01<2><1><default><default>
  21. uart_rts = port:PA02<2><1><default><default>
  22. uart_cts = port:PA03<2><1><default><default>

  23. [uart3]
  24. uart_used = 1
  25. uart_port = 3
  26. uart_type = 2
  27. uart_tx = port:PA13<2><1><default><default>
  28. uart_rx = port:PA14<2><1><default><default>
  29. ;uart_rts = port:PA15<3><1><default><default>
  30. ;uart_cts = port:PA16<3><1><default><default>
Copy the Code


I've connect tx PA13 on pi one to rx 2g iot and rx PA14 pi one to tx 2g iot
(when i connect ground, either pi one or 2g iot cannot boot)

I'm using putty (also try using picocom, kermit) on pi one

Serial /dev/ttyS3
baud 921600
also try 115200

The display on putty when 2g iot start cannot understand

am i missing something?
