USB BDM NT

[G-Body]

Hi David and all,

I received my USB BDM NT a few days ago and want to play with this dead p59 I have. I really like the jigs you and NSFW made and I hope to print one up soon. It's been so long since I did any jtag type stuff I have a couple questions to make sure I don't screw up.

Connection
BDM connector of USB BDMNT NT ECU411
Pin 1 DS
Pin 2 BERR
Pin 3 GND
Pin 4 DSCLK
Pin 6 FREEZE
Pin 7 RESET
Pin 8 DSI
Pin 10 DSO
Connect WPP to 12V with 100ohm resitor. Make sure WPP is > 11.4V when power on.

Does the u-link NT only use 7 wires instead of 8 (on all the AMD PCM`s)? The wiring info on the BDM youtube video does not have the DS wire connected.

u-link NT is replacing USB BDM NT to program MC6833X CPU.
u-link NT has the highest clock set to 9MHz instead of 6MHz. The read speed is faster then USB BDM NT.

DS pin is not used. Normally it is the power from the board to power the interface chip.
