Hi, I am having trouble booting any OpenWRT image on WRT160NL (CUR01).
I have serial console (a former Nokia 2600 data cable - it has a PL2303HX chip) access and I am trying to check the image works before flashing it (the router is online and I don't have an equivalent backup machine) so I have been trying ramdisk images.
I tried http://downloads.openwrt.org/backfire/1 … e-gzip.bin and it panics.
I also tried a similar image built via ImageBuilder from the trunk from yesterday and had a little more success.
The kernel boots, but serial console is unusable after the moment the kernel tries to setup the serial console itself.
Hit any key to stop autoboot: 0

I know the kernel works because I suspected the console is not set correctly, and I tried to see if it responds with lower speed settings, which it did (of course, with garbage). I don't think the cable length is at fault, since it works fine in all of the other cases.
I would really appreaciate some help on this. As I said before, I don't want to risk flashing directly, I want to make sure the system boots properly with OpenWRT, before doing that, hence the usage of the ram image.
Thanks.
