I have a QN9080 chip customized board.
I want to debug this chip board using JTAG interface on QN908x Development board.
Is there any document explaining the steps required for this or the setup?
I have tried the following but it is not working, can someone point out what I am doing wrong?
The setup is as follows:
1. Short Jumper JP1 on NXP QN908x Development board.
2. Take JTAG 10-pin connector and connect it to the custom board as follows:
- Connect Vcc , GND, SWDIO, SWDCLK, SWO and Reset pin.
- I have kept ISP_Detect, IF_Detect and JTAG_TDI pins open as it is not connected to the QN908x chip.
Is this setup correct or I missed something?
Attached is the 10-pin Debugger connector pinout.
Can someone please help me with this, its Urgent.
