-So I tried tjtag again and no dice. wtf. but some italian program for AR7 noticed the CPU ID as "1" so I searched and found [[http://urjtag.sourceforge.net/|UrJTAG]]. First **cable dlc5 parallel 0x378** then **detect** then **include admtek/adm5120/adm5120** and finally you should be able to use **flashmem 0x3cf00000 uboot.bin**. Of course, this is after you find libusb0.dll and ftd25xx.dll so the program will run. Neither library being utilized... wtf! But works better than getting cygwin for the old jtag tools ports.. It's flashing now, an hour later 64kb is done. I'll re-write this if it works.. I'm going to bed. What a day! All to save a $15 router. hah.

-so i woke up and no dice. i programmed the 8-bit address. soooo unless UrJtag says the Manufacturer and Chip type, it's not gonna work. Remember that. I assumed it was a supported family, but unsupported chip and thus didn't display. it's programming again now, and i'm going to work. **0x3fc00000** would be the 16-bit access to any MIPS CPU's boot-rom, which is of course mapped to flash for us. It's also mapped at 0x30000000.
+I returned from sleep and it didn't work. I programmed the wrong address. soooo unless UrJtag says the Manufacturer and Chip type, it's not gonna work. Remember that.

It's also mapped at 0x30000000. For me, the 64k image takes just under 30minutes to flash. I recommend using **noverify** when flashing.
