DCH box testing soon.
I will start testing those boxes. I will soon get one DCH70 and one DCH3416 to start collecting firmware and NVRAM on it. Please wait as those devices will only be supported on USB JTAG NT.

Testing DCH70.
Today I hooked up DCT70. I can read CPU ID but not able to get IMPCODE.
The problem should be with the TDI. Can anybody read the IMPCODE, for the test you can use DCT2500 as test target.

DCH3200 Images
I just opened my DCH3200 and took pictures. Since they are so large, I have put them in a zip. There are a few spots that look like jtag ports, but they are filled in with solder already.
Here are 2 mirrors for it:

I will upload DCH3416 next.

These boxes are just sitting around and were once activated on Comcast. They stopped working because I cancelled the service about 6 months ago. They are just sitting around and I would like to do whatever it takes to get them online again. Let me know if theres anything you guys need me to do.
Can someone identify which jtag port is the one to connect to? There seems to be 3 on both boxes that would require a 10-pin header. usbbdm, I'd appreciate any input.

I'm a programmer, so i will try to assist in anything i can, so can you tell me what the IMPCODE is? So i can go about trying to read the IMPCODE. There is this POKE command that i'm reading about, and it looks like it can help you with reading the IMPCODE, but i need to know exactly what the IMPCODE is..usbbdm wrote:Today I hooked up DCT70.

You need to read the MIPS document about EJTAG.
Actually I found why the JTAG not directly working on DCT70. It is not the pin header was wrong. It is because there is another JTAG device in front of the Broadcom chip. We need to inject more bits after we inteject the data or IR. I will resume this project after the GUI for modem is finished.
