Hi folks,

I am trying to get OpenWRT onto my Linksys WAG200G (AR7-based) router. I have built a serial cable, and will build a JTAG cable too shortly.

First problem though is that the ADAM2 bootloader does not allow me to interrupt the boot process, nor does it provide FTP/TFTP recovery support. So, if I download a bogus kernel and/or root fs, I'm bricked. I figured it would be a good idea to build a new version of ADAM2 from the sources originally provided in one of the older Linksys GPL tarballs, linked from OpenWRT/ADAM2. However, I'm not sure whether the flash chip is an Intel or AMD chip, or whether the other parameters need to change:

 $ cat cy_codepattern.mak
#FLASHTYPE=INTEL

FLASHTYPE=AMD
FLASH_SIZE=4
DRAM_SIZE=16
BOOT_SIZE=128

The flash and dram sizes are correct, but I don't know what BOOT_SIZE means. I *THINK* that the FLASHTYPE is correct, based on various infos I have seen (boot logs, primarily, I think).

Any suggestions?

Thanks!

Rogan

to check bootup process use modified qemu, look http://woytekm.googlepages.com/runningl … wareinqemu for instructions/details.

Be carefully with the JTAG. I have destroy my router with the first try but I dont understand why..

Who can help me to repair it? One or more (?) transistors are dead.

Probably size of bootloader partition in KiB

flash is a macronix mxs081321 4mb

the router is similar to this Netgear DG834G v1  ant the netgear is supported by openwrt here is the installation instruction for the netgear it is similar to the wag200
