Hi,

omap serial is obsolete why does linux-yocto keeps using it.
seondly, machine config should enable both consoles ttyO0 and ttyS0 if
you know that at least one kernel is using ttyO0
How about picking whatever works for you in the kernel conf and in machine
conf?
SERIAL_CONSOLES = "115200;ttyS0 115200;ttyO0"
SERIAL_CONSOLES_CHECK = "${SERIAL_CONSOLES}"
Like this on the first boot either ttyO0 or ttyS0 should be picked
automatically.
Yes, this is doable. Would you mind send a patch?
Sorry for answering so late... good hint, I missed SERIAL_CONSOLES_CHECK
I try this change and report, give me some time...

and on my beagleboneblack linux kernels with 8250 serial driver enabled

are booting.
Unfortunately it took me some time, until I realized that my settings
in auto.conf do not work, because in beaglebone-yocto.conf
SERIAL_CONSOLES = "115200;ttyO0"
is set ... May a
SERIAL_CONSOLES ?= "115200;ttyS0 115200;ttyO0"
is friendlier ?
Should I send a formal patch?
bye,
Heiko
