STM32WBA52 programming on custom board

suvendusahux · ‎2024-11-19

I am trying to detect my stm32wba52cg bare chip with my developed custom PCB board with onboard stlink as external programmer from a discoveryboard but its showing this msg-

Can not connect to target!
Please select "Connect Under Reset" mode from Target->Settings menu and try again.
If you're trying to connect to a low frequency application , please select a lower SWD Frequency mode from Target->Settings menu.
No target connected.

this are my connection for programming my wba52 controller-

discovery stlink stm32wba52

swdio swdio

swclk swclk

Below is my schematic attached:
I have exposed all the pins.

Hello @suvendusahux

As I can see on your schematic, you are using the PA13 as SWCLK and PA14 as SWDIO. But as you can see on the Table 24 of the DS14127, PA14 is the SWCLK pin and PA13 is the SWDIO pin:

What do you mean by that - Literally a bare chip; no PCB at all? A custom PCB ? Other?

A custom pcb with stmwba52.

Thanks - I updated the title to reflect that.

Please post the schematic of your board.

Some good, clear photos of your setup would also help.

I am trying to load the BLE_heartrate_ota example to my wba52 controller I am getting these logs after RUN and DEBUG -

PA14 is the SWCLK pin and PA13 is the SWDIO pin i swaped the pins and it detected the mcu but I am getting Target is not responding message every time I try to run or debug the BLE_heartrate_ota example for stm32wba52.

I Tried to connect buttons to my mcu as shown in nucleo board but its not showing in my st ble toolbox when I press B1 connected to PC13.

These are some logs from usart1 when I press reset button.
