Re: [Gumstix-users] Kernel panic on setting essid

Good to see that you have some success!

What are you using to flash your kernel and filesystem (ethernet, serial,
TFTP?) ?  Are you using a wifistix with a connex board ? Did you have to
flash the "uImage" in addition to the "root_fs" ?  I was slightly confused
if the uImage was to be flashed for the connex boards as well....
