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.

Dear Betadine,
In order to attach to Multilink BDM for JM32 you need a 2x3 std 100 mils male pinhead in your PCB. It's the cheapest pinhead you can find.
The pinout is like you said and the signals are straight connected to the uC pins: VDD, GND/VSS, BKGD and /RESET.
I hope it helps.
Cheers,
Celso
