SOLVED: Basic loading of nut/OS applications via TFTP

[Nikolas Becker]

Hello Tim,

thanks for the help. Here is what happened: After trying the command tftpboot, U-boot answered:
*** ERROR: 'serverip' not set
So it looks like the u-boot manual is faulty, since there is nowhere mentioned that the parameter serverip has to be set. After setting this variable to the ip of my tftpserver, it is downloading the program and I was able to start it.
Perhaps another question: is it normal that the http-server example does not really work? I can connect to the server, but besides the basic index page, all links just return 404.

Mit freundlichen Grüßen
Sincères Salutations

Hello Nikolas,

as an alternative you could try the following commands in U-Boot:

dhcp
tftpboot 0x20000000 172.16.1.105:httpserv.bin
go 0x20000000

The first command initializes the network. The second command loads the image and the third runs it.

Best regards,
Tim Schendekehl

It should work, probably except the old flash animation.

Anyway, the code in httpd is older than this list. We have newer code
examples in uhttp...

http://www.ethernut.de/en/documents/uhttplib.html

It is much more flexible, but also a bit more complicated.

Regards,

Harald
