    Hi,

    I found a backup of LE11.0.1 and with this the symlinks /dev/serial0 and /dev/serial1 are created already, with date 02-16-2023. I am using the Joy-It Multimediacase, and seems, that the firmware of the built-in extension board needs this to shut down and reboot properly after LE was shut down.

    Would be nice, if the symlinks will be created again in future LE releases, to keep compatibility

    Regards - Helmut

    Hello,

    after update from LE 11.0.1 to 11.0.3 the /dev/serial0 and /dev/serial1 have vanished. Access with pyserial does not work any more.

    With miniuart-bt in config.txt, there is /dev/ttyAMA and no /dev/ttys0. Without miniuart-bt, vice versa.

    Unfortunately, from recent 11.0.5 the downgrade to 11.0.1 is no longer possible. Same occurs with a fresh clean install of LE 12 nightly.


    config.txt:

    Output of dmesg | grep tty:

    Code
    [    0.000338] printk: console [tty0] enabled
    [    1.649286] fe215040.serial: ttyS0 at MMIO 0xfe215040 (irq = 38, base_baud = 62500000) is a 16550
    [    1.649386] serial serial0: tty port ttyS0 registered
    [    1.684558] fe201000.serial: ttyAMA0 at MMIO 0xfe201000 (irq = 53, base_baud = 0) is a PL011 rev2
    [    1.684808] printk: console [ttyAMA0] enabled

    Any help? is it a bug? Thanks - Helmut
