Tried, nc -lup 6666 192.168.1.76 6666 on 192.168.1.78, still no messages print. It may be the time to order a serial cable.by suo_jian - uBoot
Hi bodhi, Checked with new command, still no message shown, is it possible the nc message is not sent to 192.168.1.78, but somewhere else?by suo_jian - uBoot
Hi bodhi , I run netcat-traditional, and listening at 192.168.1.78, but there is no output. any other suggestion?by suo_jian - uBoot
1. Did you upgrade the kernel on an existing rootfs, or create a brand new rootfs? I create brand new rootfs. 2.Your envs for netconsole look OK. How did you run nc server? from a Windows, Mac, or Linux box? the netcat (nc) programs on other OS might be not working properly. You can try different nc versions to see if any behave differently from another. I run it on a ubuntu(14.04.1 LTSby suo_jian - uBoot
Hi, I have a pogo e02, and wrote image to NAND by following the instruction, ther is no any error during the writting. I also create Linux Kernel 3.17 (FDT) on a usb flash, and plug to the usb, after reboot, I do not see any message output from netconsole server. The light on pogo plug turns to green, but there is no connection(ip), i can't access the pogo. I tried to remove usb flaby suo_jian - uBoot
