[U-Boot-Users] telnet server on u-boot

Hello all,

For some remote instruments, I need to be able to have a telnet access to the boot in case of my Linux kernel and file system are down (after an upgrade for example). I don't think that u-boot provide telnet support and I had a look at another boot project called redboot that provide such a functionality. I have a couple of questions : Does anybody see another solution than telnet to control a remote instrument? Has anybody already tried to add telnet server to u-boot? It seems to be a challenging task because we need to add TCP support. Has anybody used both u-boot and redboot and can point me the main advantages and drawbacks of both?

Thanks for replying,
