Problem with dumptool please help

[ip330HD]

Hello, im trying to use x300t dumptool on Scientific Altlanta IP330HD and all what i always get on screen is
CPU Chip ID 1111111111111111111111111110 (FFFFFFFFE)
**** Unkown or No CPU ID Detected  *****
Issuing Processor / Periperel Reset ... Done
Halting Processor  .... <Processor Entered Debug Mode!> ... Done
Clearing Watchdog ....

and stands on "Clearing Watchdog ...." forever.

I checked JTAG cable like milion times and all is connected okay and Jtag enable pin is connected.

Can i even use x300t dumptool on that set box or there is some other version of program, and please i there is any other version please link it. Thank you very much in advance.

the dump tool is specific to the x300t in regards to the memory location where the decrypted flash is stored in RAM.
this might be different on other boxes.

anyway, the CPU ID should be displayed correctly on any device with a JTAG port.
what kind of cable did you build ?

I also had problems when including a buffer IC... only using resistors seems to give best results (but can also damage parallel port or the SMP)

i have normal JTag cable like on t-hack wikki, no wiggler. And when im using WRT dumptool i get
c:\wrt54g_o -probeonly

====================================
WRT54G/GS EJTAG Debrick Utility v4.8
====================================

Probing bus ... Done

Instruction Length set to 5

CPU Chip ID: 00001000011000110000000000000001 (08630001)
*** Unknown or NO CPU Chip ID Detected ***

*** Possible Causes:
   1) WRT54G/GS is not Connected.
   2) WRT54G/GS is not Powered On.
   3) Improper JTAG Cable.
   4) Unrecognized CPU Chip ID.

thx

strange... the differences to the wrt54g tool are very small.

- added SMP cpu-id,
- a fix for the debug-mode exit
- memory mapping to have access to the ram
- default dump values to get the ram area with the decrypted bootrom

you should be able to use the unchanged tool, with the correct parameters

which parameters do you suggest?
