Hi all,
there is an issue with the current network stack using netconsole. It's impossible to use network commands as TFTP inside netconsole, because they try to run as atomic network commands.
The issue was already reported by Stefano Babic in 2010: [U-Boot] NetConsole and network API http://lists.denx.de/pipermail/u-boot/2010-August/075535.html
I run into the same problem: [U-Boot] netconsole: USB Ethernet connection dropping with ping or tftpboot http://lists.denx.de/pipermail/u-boot/2015-February/203838.html
I have looked at the current network stack. The stack is based on the concept of atomic network commands. The implementation for netconsole looks very confusing.
Sascha Hauer has reimplemented the network stack for Barebox: http://www.spinics.net/lists/u-boot-v2/msg00914.html
Looking at the current implementation of net.c looks very clean and well-designed.
What do you think about porting this to U-Boot?
Best regards Jörg Krause
