I locked myself out fiddling with the bootscripts. Which got saved under jffs2. So now my nslu is not booting anymore fully complete so i can't fix the bootscripts.
I'm using a serial console, and i managed to change the cmdline of the kernel.
cmdline = *= root=/dev/mtdblock4 rootfstype=squashfs,jffs2 console=ttyS0,115200 init=/bin/sh noinitrdgives me a kernel panic (no sync). The original commandline dies at some point in the bootscripts (it's a loop somewhere - which i could fix if i had access to the jffs partiion)
I tried hitting Ctrl-C when it says to continue in failsafe mode. Nothing happens. Tried the reset button procedure. Pretty sure, it's not working on nslu2. I noticed that when i keep the reset button pressed it stops booting, but when i release it it continues nicely.
I was thinking if i could boot somehow without mounting the jffs2 partition. Is there any method to do that without actually erasing it?
here's the log:
