[En-Nut-Discussion] Basic loading of nut/OS applications via TFTP

[Tim Schendekehl]

Hello Nikolas,

U-Boot needs to know the IP address of the tftp server. You can set it using the following commands:

setenv tftpserverip 192.168.0.1
saveenv

Replace the IP address with the one of your server. After that try to boot the application again with:

run tftpbootnut

Best regards,
Tim Schendekehl

I try to get started with the Nut/OS development, but fail to start the example projects. I compiled several examples (simple, httpd, httpd_simple) and installed a tftp-sever (tftpd64). I was able to receive the .bin files from another PC in the network, so my server seems ok. I tried to follow the u-boot environment guide for loading nut/OS applications.
