The Linksys WAG200G router has a TI AR7 SoC and a 4MB Flash layout
similar to the Netgear DG834v3 router [1].
Below is an example of a successful flash recovery, using a TUMPA,
connected to the MIPS EJTAG 2.6 header (JP102) of the router.
WAG200G [2] TUMPA [3]
Desc Pin Pin Desc
------------------------
nTRST 1 3 nTRST
TDI 3 5 TDI
TDO 5 13 TDO
TMS 7 7 TMS
TCK 9 9 TCK
nSRST 11 15 RST
GND 2 4 GND
Note that nSRST is optional to halt the CPU, but is required to probe
the flash. For instance, recover the kernel with:
$ sudo ./src/openocd -s tcl \
-f interface/ftdi/tumpa.cfg \
-f tools/firmware-recovery.tcl \
-c 'board linksys-wag200g;
reset_config srst_only;
flash_part kernel /path/to/kernel.bin;
shutdown'
