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

[    0.530712] dev:f1: ttyAMA0 at MMIO 0x20201000 (irq = 83, base_baud = 0) is a PL011 rev3
[    0.873131] console [ttyAMA0] enabled
