Hi All,
This is related to the post here: http://www.mail-archive.com/u-boot@lists.denx.de/msg06428.html My use case is similar... updating the kernel remotely to a deployed, physically inaccessible system.
I am considering the same thing (TFTP server in U-Boot), but I believe I have a good reason for wanting it. At the same time, I don't want to waste effort if others have a better idea for how to accomplish what I need.
The main sticking point for me with using TFTP client from U-Boot is firewalls. My system will be accessed by machines inside a firewall and if I use TFTP client from U-Boot, then I must poke a hole in the firewall... however, I have no control over the firewall so that isn't possible. If the host machine connects to the U-Boot running TFTP server, then all is well.
I intend to control U-Boot remotely using netconsole. Is there a better way to push files to U-Boot over netconsole than implementing TFTP server? It seems like this would be a common concern, so it seems likely that it has been solved (in some other way, since there is no TFTP server support in U-Boot).
Thanks, -Joe
