I decided to give it a try, the problem is that if I fail I have no way to request help online. hope it works.

I have a DPC2100R3 which has a Etrontech Flash chip. I wanted to extract the CFG from this modem.

Created a JTAG using the schematics from rajkosto, but CPU wasn't detected. So instead reversed it like racky29 said on that thread and got it to work. It still says "Flash : Unknown" and trying to extract CFG says that "address out of range"

Any help??
Want to copy the CFG to DPC2100R2

can you take some pictures of the board and close up of the chips?

Here are some images of the chips

I think they just reduced the number of components compared to the DPC2100R2...
I have both of them side-by-side... There is the USB missing in R3

merged the threads as they are both on the same subject (and i only want to write this once)

the winbond and Etrontech are not the flash chip as this is a spi modem
the spi chip is the 8pin soic chip next to the white serial header so can 1 of you kind people tell me the chip number
