Hi.

I´m like more than 1 hour trying to figure out the footprint for the BDM Header for a JM32 MCU.

It´s a very Newbie Question.

 

If I´m considering to buy the 99$ ... USBMULTILINK for only programming my MCU. Then I need a 6 pin header for which the MCU's DS says:

 

!RESET

VDD

GND

BKGD/MS

 

this signals must be connected, ok.

 

USBMULTILINK says about the connector

 

BGND -  1       2 -  GND

      NC - 3        4 - RESET

      NC - 5        6 - VDD

 

Then... I suppose that BGND is BKGD? cause it seems like a GroundB

mmmm it says RESET, and the DS says "!RESET" (inverted) ¿is MULTILINK lying?

 

Ok if this is true, how I make the footprint?

Ive searched a lot but I dont find any more info about this.

 

Dimensions? Pin width? ... something?

 

Regards.

 

Cristian.
