Thomson TG784n

I've search around the forum and I didn't find any information about this router

This router is very popular in Portugal and its the most complete I ever saw.

- RAM 512MB - H5DU5162ETR-E3C
- FLASH 32MB / 256Mbit (16Mx16) - Intel JS28F256 M29EWL (http://www.arrownac.com/services-tools/design-tools/arrowedge/parts/2009/vol1/pdfs/numonyx_datasheet.pdf)
- 2x USB ports
- VOIP (2 ports)

Services:
- FTP
- TELNET

I had my router locked so I look up for a JTAG and this is the information of the JTAG log (can be useful)

Pinout for this 8 pin JTAG :
Code:
8 - N/C (Diode missing to 3.3V)
7 - TDI
6 - TDO
5 - GND
4 - TMS
3 - TCK
2 - N/C (3.3V Pullup / Possible nTRST)
1 - N/C (resistor missing to 3.3V)



JTAG log:
Code:
brjtag1.9f_exe>brjtag -probeonly  /showppb

+1 for this routers. The wifi is actually very good (I'm surprised) and the hardware seems to be stable.
