Hi everyone,
I have a JLink EDU mini (this one), connected to this breakout board. I am trying to get it to connect to a bluetooth module with the following 4 pins: 3V3, GND, SWDIO, SWCLK.
For some reason, the uVision IDE says that while the JLink is found, the connected device is not. I have a suspicion as to what's wrong, but not sure. Two questions:
1) I'm connecting the JLink to the breakout board using this cable, but can't figure out which way the 2x5 attaches to the JLink (it could be connected in two configurations). I tried both and neither work, but if you know that would cut my debugging time in half
2) I'm connecting the following wires:
Vref on breakout <---> 3V3 on module
GND on breakout <---> GND on module
SWIO on breakout <----> SWDIO on module
CLK on breakout <----> SWCLK on module.
I think Vref is simply a reference, and the breakout doesn't actually output power. If so, how do I set this circuit up? I think my laptop outputs 5V through USB, but not sure, and it seems like the module runs on 3.3V.
Any help is much appreciated. Thank you very much for your time!
