Enable Hardware Features
|
||
|
|
========================
|
||
|
|
|
||
|
|
Some boards require some manual configuration to turn on/off certain features
|
||
|
|
|
||
|
|
In some cases, the procedure is "less than obvious", so we document some basic examples here.

# Orange Pi Lite
|
||
|
|
|
||
|
|
## Enable serial /dev/ttyS3 on pins 8 and 10 of the 40 pin header
|
||
|
|
|
||
|
|
Update the FEX configuration (which is compiled into a .bin) located at /boot/script.bin
|
||
|
|
|
||
|
|
Decompile .bin to .fex
|
||
|
|
```
|
||
|
|
cd /boot
|
||
|
|
bin2fex script.bin > custom.fex
|
||
|
|
rm script.bin # only removes symbolic link
|
||
|
|
```
|
||
|
|
|
||
|
|
Edit .fex file
|
||
|
|
```
|
||
|
|
[uart3]
|
||
|
|
uart_used = 1 # Change from 0 to 1
|
||
|
|
uart_port = 3
|
||
|
|
uart_type = 2 # In this case we have a 2 pin UART
|
||
|
|
uart_tx = port:PA13<3><1><default><default>
|
||
|
|
uart_rx = port:PA14<3><1><default><default>
|
||
|
|
```
|
||
|
|
|
||
|
|
Compile .fex to .bin
|
||
|
|
```
|
||
|
|
fex2bin custom.fex > script.bin
|
||
|
|
```
|
||
|
|
|
||
|
|
Reboot
|
||
|
|
|
||
|
|
Notice that /dev/ttyS3 appears. That is your new UART device.
