Programming XMC1302

[#1]

Dear Team,

I am a first timer with XMC series. I am using XMC1302Q040X0200 micro-controller for Inverter design application.

I bought a XMC1300 CPU Card V1. I have made by PCB with micro-controller and trying to program it using 2x4 pin connector provided with the boot-kit. In the design, SWD connected to P0.14 and SWCLK is connected to P0.15. PC_TXD is connected to P1.3 and PC_RXD is connected to P1.2.

I am not able to program the micro-controller in this configuration. Can you please suggest if possible solution path.

Cheers!

Did you miss the GND?

To program/debug another board, only 3 signal pins are necessary: SWDIO, SWCLK and GND.
If you still want to use the virtual serial port, you should disconnect the two pins from the original XMC1300 on the boot kit first.

I have checked my XMC1100 Boot kit, the SWD and SWCLK are indeed on the P0.14 and P0.15. Maybe you should try to add the GND signal.

Have you solved the problem.

If your XMC1302 is a new blank chip. You should first change the BMI configuration via the UART. Because new chip is configured as such.
