Attached is the output from a -probeonly /flash_debug.
The router is an E3000 (real one) with an MXIC MX29LV640EBTI-70G flash chip.
Using version 3.0.2-RC2-1, I need to use /fc:107 to address the chip. Using that fc.. I can read & write to the chip. However, writing is REALLY slow.. 3+ hours for a 256k cfe.
I used your preferred adapter.
atm.. I can test no further. A member sent me a working E3000 to enable jtag & install jtag & serial headers cuz I guess he plans on bricking it .
I have to send the router home. The two I own, I messed up the pads trying to enable jtag. (Since then, I got it figured out ) I can test on the next brick I get.. Or.. this would be a perfect time for someone to donate a router to you:

Unfortunately that will not happen. Although there is a large group of "modders" out there, if the manufacturer started adding jtag headers to their routers, then most people would be able to fix any problems with their router. They (the manufacturer) would lose money because less people would upgrade to the latest greatest model.
It is sad really, but I would love to see those jtag headers too. _________________ E3000 22200M KongVPN K26

I no longer have a RT-N16 to test on, left it in Odessa, Ukraine. But your dealing with a 8bit bus here, that why is takes so long. I do have a E1000v2 to test on, that is almost the same. It did not take me 3hrs..but it did take probably an hour. It may be possible to speed up the flash, because on the E1000v2, the CFE is actually 128k or less, not 256k. It may be possible to just flash the 128k and save some time, but I have not tested that. _________________ Want JTAG support - Donate a router
