Hello,
we need to change the tty on which busybox is sitting. Right now I could change
the UART for the kernel and all program output after the boot to our favorite
UART (via kernel cmd line). But the login promt and all interaction with the
device is still on the old UART. So I guess it's a busybox configuration issue.
Furthermore, when I try tty after login, it gives me: /dev/ttymxc4 (we want to
use ttymx1).
I looked here https://busybox.net/downloads/BusyBox.html and in menuconfig
for an option to change the UART interface but couldn't find any. Furthermore I
added
::respawn:/sbin/getty -L ttymxc1 115200 vt100
and this
ttymxc1::respawn:/sbin/getty -L ttymxc1 115200 vt100
to inittab to change the UART with no luck.
Could someone here point me to documentation or give me a hint to achive this?
Generally, the console setting comes from our <machine>.conf. eg:
for beaglebone:
./meta-yocto-bsp/conf/machine/beaglebone-yocto.conf:
SERIAL_CONSOLE = "115200 ttyO0"
This gets processed in bitbake.conf:
SERIAL_CONSOLES ??= "${@d.getVar('SERIAL_CONSOLE').replace(' ', ';')}"
later, based on the init manager:
busybox, systemd-serialgetty, or sysvinit-inittab use it.
In this case, updating the "<machine>.conf" should help.
Thanks in advance, all the Best,
Jakob
