U-Boot access through Netconsole
Posted on 2016-06-15
I am running Fedora 19 and I am trying to set up Ethernet access to the U-Boot of an embedded device. I have already loaded a build of U-Boot with Netconsole enabled, but I do not know the basic steps of getting connected from Linux to U-Boot via Netconsole.
Here is what I have done so far.
In U-Boot (192.168.1.1):
#setenv nc 'setenv stdout nc;setenv stdin nc'
#setenv ncip 192.168.1.100
In Fedora 19 (192.168.1.100):
#nc -l -u 6666 &
#./uboot/tools/netconsole 192.168.1.1 6666
NOTE: the interrupt signal (normally ^C) has been mapped to ^T
After this point, there is no output on the Linux screen so it may not have connected to U-Boot.
What are the proper steps for getting Netconsole working between Linux and U-Boot?
