orange pi One enable Uart3

ayalshi

hello I have downloaded armbian debian for orange pi one. I need to enable uart3.

I have tried to change script.bin with those settings:

1. [uart3]
   
2. uart_used       = 1
   
3. uart_port       = 3
   
4. uart_type       = 2
   
5. uart_tx         = port:PA13<2><1><default><default>
   
6. uart_rx         = port:PA14<2><1><default><default>
   
7. ;uart_rts        = port:PA15<3><1><default><default>
   
8. ;uart_cts        = port:PA16<3><1><default><default>

Copy code

but I think that made a mess in the operating system, dont know why, maby those pins use for other stuff else where?

the script.bin delete itself from /media/boot I dont know what happened I keep getting errors on the startup...

thanks.

I think it's right
My script.fex is below.

[uart0]
uart_used = 1
uart_port = 0
uart_type = 2
uart_tx = portA04<2><1><default><default>
uart_rx = portA05<2><1><default><default>

[uart1]
uart_used = 0 → 1
uart_port = 1
uart_type = 4 → 2
uart_tx = portG06<2><1><default><default>
uart_rx = portG07<2><1><default><default>
uart_rts = portG08<2><1><default><default>
uart_cts = portG09<2><1><default><default>

[uart2]
uart_used = 0 → 1
uart_port = 2
uart_type = 4 → 2
uart_tx = portA00<2><1><default><default>
uart_rx = portA01<2><1><default><default>
uart_rts = portA02<2><1><default><default>
uart_cts = portA03<2><1><default><default>

[uart3]
uart_used = 0 → 1
uart_port = 3
uart_type = 4 → 2
uart_tx = port:PA13<3><1><default><default>
uart_rx = port:PA14<3><1><default><default>
uart_rts = port:PA15<3><1><default><default>
uart_cts = port:PA16<3><1><default><default>

Hi,
I found out what the problem was. the fex script was ok, I just created unnecessary files inside the boot folder, wich cause the bin script to delete it self. I removed unnecessery files and it worked.
