Hi.
I've just posted a proposal of burning open-source image onto D-Link DI-523 router/AP onto my private forum: http://abuse.bbs.pl/viewtopic.php?f=9&t=5
Sorry for not posting it here, but I prefer to keep all of my stuff there. I hope that's not a problem.
I've also posted the MMC driver there, since the original website (http://kiel.kool.dk) is dead for a long time.
I would like to hear from you about that D-Link concept. I'm currently stuck on the JTAG stuff and maybe some of you could help.
Thanks!
