I would like to connect a Segger J-Link with the RAK4631 with a RAK19007 board, but I don´t know where in the RAK19007 I have to connect the flat cable connector that it comes from J-Link?
I have the J-Link connector description, but I don´t know where to connect in the RAK19007 board.
There is no JLink interface on the base board.
You connect the Jlink to the SWD interface on the WisBlock Core module itself.
My connections are like this:
A quick question: When you say: " The 3V3 connection is going to VRef on the Jlink and it is NOT supplying the RAK4631", the 3V3 source, Could it be the RAK19007 J12 pin 1 VDD?
Sorry for being unclear.
With “The 3V3 connection is going to VRef on the Jlink and it is NOT supplying the RAK4631” I mean that you have to supply the BaserBoard over USB or battery while using the JLink.
The JLink adapter is not providing supply voltage to the board.
Yes, the 3.3V is supplying the WiSDuo module AND has to be connect to VTref of the Jlink.
VTref tells the Jlink adapter the required voltage levels in TMS, TCK and RESET.
