DPC2100R2 TFTP command

[rickanie]

In telnet I forgot the command to upload haxoware to spi chip. (Cisco DPC2100R2)
tftp -p -l 192.168.100.1 69?? Its something like that. Can someone refresh my memory please.

Code:

Set your computers ip to 192.168.100.10
  Set up a TFTP server with haxorware11revXX-XXXX.bin in its root
  Make sure the haxorware webgui isn't currently open
  Connect to modem with hyperterminal or telnet to the IP 192.168.100.1
  Enter your username and password
  cd /ip
  ipconfig 1 release
  y
  dload -i 1 -l -f 192.168.100.10 haxorware11revXX-XXXX.bin
  y
  cd /
  reset

Sorry not trying to HiJack your thread but I was wondering does the DPC2100R2 have a Jtag? How are these modems flashed?

[drewmerc]

they have both serial and jtag

That Bus Blaster looks petty bad. I like to test with one of those.

i use an home made ft2232 usb jtag and it kicks ass you can write a firmware in 5 seconds but the busblaster is a hundred times better than mine, i want one to

[rickanie]

I've seen several different homemade jtags around but I cant remember the one your talking about. (FT223) Can you test program ambit 256 with yours? What GUI you use for it? pretty cool man!

[drewmerc]

bottom header is jtag top is spi(256) and ttl is hidden in picture
for jtag i use toms (when doing modems) spi i use flashrom
i used happyjtag2 schematics when building mine, then spent a lot of time mithering Ian at dangerous prototypes to make a jtag he first made the busblaster v1 (which is like the happyjtag2) then added the cpld this allows to to emulated different highend jtags and give a speed boost in the v2 (i recommend you buy or build one of these)

anyways here's the pic it's old and looks rough (guess i can redo it now i have a new iron)

Looks badass, good work. Please give me the link to the tut or send me the schematic drawings when u get a chance and If you don't mind me using them. thanks
