Hi,
long time ago I was playing with switching among consoles. I have two IPs with the same driver where main console is probed and used which is visible via dm tree.
serial 1 [ + ] serial_zynq | |-- serial@ff000000 serial 2 [ ] serial_zynq | |-- serial@ff010000
then I have also dcc which can be also used as a console
serial 0 [ ] arm_dcc |-- dcc
Lastly I have enabled netconsole feature.
I have no problem to switch between serial@ff000000 and nc but I can't switch it to dcc or second instance.
dhcp setenv ncip 192.168.0.105 setenv nc 'setenv stdout nc;setenv stdin nc' setenv dcc 'setenv stdout dcc;setenv stdin dcc' setenv serial0 'setenv stdout serial@ff000000;setenv stdin serial@ff000000' setenv serial1 'setenv stdout serial@ff010000;setenv stdin serial@ff010000' run nc
and then via netconsole
run serial0
works to get back.
Console info is showing only available and registered instances.
ZynqMP> con List of available devices: serial@ff000000 00000007 IO serial 00000003 IO stdin stdout stderr nulldev 00000003 IO nc 00000003 IO
It means the question is how to probe second instance of serial_zynq serial@ff010000 and dcc. I expect when probe is done it will show up in console list and switch is possible.
I found SERIAL_SEARCH_ALL symbol but it is just search not probe.
I am quite sure that it was working in past but not sure if this was before DM but I would like to know how you are doing it/testing it today.
Thanks, Michal
