Programming the board? about hawk

[J-P-Projects]

I have an assembled board ready to program.
Could anyone comment of how this is done?

It may be overkill, but I've picked up a J-LINK EDU which (should) work with pretty much any Cortex-M μC. While googling around I saw that the black magic probe may also work as well. I'll update this issue when I can confirm with my own hardware.

@GHvsBB Okay, I can confirm that I can program the board using a J-Link (EDU model). I used the SWD debugging connection. You'll need to connect up the header pins as follows:

Header pin	Function	JTAG 20-pin connector
1	SWDIO	7
2	+3.3V	1 (VTRef)
3	SWCLK	9
-	N/C	-
5	RESET	15
6	GND	4

I'd imagine that there's some kind of breakout/adapter but I just used jumper wires. The VTRef connection is so that the debugger knows the board voltage level (3.3V). There's a separate +5V pin (no. 19) that could be used to supply power to the board (since the board has a voltage regulator), but I didn't use it.

Sorry - I'm not used to having issues in my repos and totally didn't notice your question!

I used a cheap ST-Link V2 clone I found on eBay to program it with SWD.

I am planning to write this up at some point, although it ended up being more complicated than I expected because it required OpenOCD to be patched because of the cheap programmer!

If you're interested, I could write up what I did and run that by you. I was thinking of blogging that anyway.
