I am trying to run the loopback test between GPIO14 and GPIO15 on raspberry pi 5. I tried
groups yousef
- dialout is included in output.
sudo raspi-config
3. Interface options
16. Serial port
login shell: no
enable: yes
sudo minicom -D /dev/serial0
but no characters are echoed
I also added
enable_uart=1
dtoverlay=uart0
to /boot/firmware/config.txt
I checked /boot/firmware/cmdline.txt, I forget what you are supposed to delete, but I think it's not there.
I also tried a python3 script that chatgpt suggested, but nothing happened.
I am connecting GPIO14 and GPIO15 through a 1 KOhm resistor.
Are there any suggestions?
Are there any suggestions?
Check the Documentation. Ref: Configure UARTs - https://www.raspberrypi.com/documentati ... gure-uarts
I strongly suspect that your efforts are related to using the serial port presented on the little Debug Header. RasPiOS Bookworm on an RPi[5] is configured differently to earlier models.
