Couple of questions I should have asked earlier:
Disabling the getty service on ttyS0 should be a one time thing unless one or more of the following applies:
You may also want to try disabling the serial-getty@serial0 service if you have one.
- Which model Pi? (I'm guessing not a Pi5 or 500 as those don't have /dev/serial0 or /dev/ttyS0. At least mine don't.)
- Which OS and which named release of it are you running?
- Booting to desktop or command line?
- Does your Pi have onboard Bluetooth? If so:
- Is it enabled?
- Which UART is it using?
Disabling the getty service on ttyS0 should be a one time thing unless one or more of the following applies:
- You have the read only root filesystem overlay enabled.
- Your cmdline.txt includes
Code:
console=ttyS0 - Your cmdline.txt includesand /dev/serial0 points to /dev/ttyS0
Code:
console=serial0
You may also want to try disabling the serial-getty@serial0 service if you have one.
