 |
|
Hello,
I have a stripped-down kernel, and I don't have /dev/ttyAMA0 (the serial console via the GPIO port).
Do you know which module to activate?
Kind regards,

Hi,
you should check for these options in "Non-8250 serial port support":
| Code: |
CONFIG_SERIAL_AMBA_PL011=y
CONFIG_SERIAL_AMBA_PL011_CONSOLE=y
