Topic: ZyXEL P-2602HWN-D7A, how-to build and exec OpenWRT image?
I started a wiki article for a ZyXEL router but I stuck with building an appropriate image and also I'm not sure how-to flash it correctly and execute it.
Here's my approach, correct me if I'm wrong:
1) Use openwrt-buildroot (12.09 final):
Target System: TI AR7
Target Profile: Annex-A DSL firmware
Target Images: ramdisk, Compression (lzma)
2) This produces an image in bin/ar7/openwrt-ar7-initramfs.bin
3) I tried upload it into the RAM section (RAS Code part, see wiki) of the router with the command: ATUP9402c000,422694.
ATGO(x) run program at addr x or boot router
to boot the image results in an error:
Exception occured! EPC = 0x9402C000 CAUSE = 0x00808028 STATUS = 0x10007C03 $RA= 0x9401DB68
I somehow followed this example: http://wiki.openwrt.org/doku.php?id=oldwiki:openwrtdocs:hardware:zyxel:p_335wt
I'm not sure how to build a big endian image, because I guess it's necessary for this router?
Thank you in advance for any hint.
