Hi,
I built u-boot with CONFIG_NETCONSOLE=y. It works, but how can I set up u-boot so that after rebooting, it automatically (ie. w/o manual interaction) goes into netconsole mode?
Ie. controlling the device remotely via netconsole by using the tools/netconsole script on the host as shown in doc/README.NetConsole, but there only a manual setup is given. For auto-starting netconsole I put these commands into boot.cmd and compiled it to boot.scr on the device:
setenv ipaddr 192.168.1.7 setenv ncip 192.168.1.2 setenv nc 'setenv stdout nc;setenv stdin nc;setenv stderr nc' run nc
At boot the netconnect connection seems to work as I get some output on the host, but after only a few seconds the device reboots itself:
root@xy:/.../u-boot# tools/netconsole 192.168.1.7 Board out port: 6666 Board in port: 6666 NOTE: the interrupt signal (normally ^C) has been remapped to ^T ncb: not found #MYINFO: the following output comes from the remote board via netconsole: SCRIPT FAILED: continuing... scanning bus for devices... data abort pc : [<7ef94f8e>] lr : [<7ef911a1>] reloc pc : [<4a01af8e>] lr : [<4a0171a1>] sp : 7af515b0 ip : 0000001c fp : 000000c0 r10: 00000000 r9 : 7af59ed8 r8 : 00000000 r7 : 7af51830 r6 : 7efd3f54 r5 : 7efdb9b8 r4 : 7efdb9b8 r3 : 00000000 r2 : 00000000 r1 : ea000016 r0 : 7efdb9b8 Flags: nZcv IRQs off FIQs off Mode SVC_32 Code: e92dbd10 f8d045f0 b0858080 1000f8d8 (f8d14604) Resetting CPU ...
It seems one needs some more commands when doing it inside boot.scr, or a different method. Or is the use of the envvar "nc" above maybe buggy: recursive definitions maybe? [I just followed the above u-boot doc]
Is such an auto-start of netconsole possible at boot, and if yes how?
Thx
