SWD via STM MCU is possible?

Only in theory: Port versaloon (or CMSIS-DAP, both are open source on github) to your STM MCU variant, then connect to a PC via USB and use OpenOCD to do the heavy lifting.

I practise its much faster to order an JLink debugger.

Priyanka,

Thank you for your response. I will check with Murata if the MBN52832 part comes with any type of bootloader.

I came across this blog post (+) Serial Wire Debug Port Interface for nRF52832 - Blogs - Nordic Blog - Nordic DevZone (nordicsemi.com) and was wondering if it would be possibly to load the hex file using the SWDIO and SWCLK pins if they are connected to the STM MCU on our board.

Thanks for your help.

HI Lekha,

You will need a J-Link debugger in order to flash a firmware onto the SoC. In case you need to flash the hex file using UART, you can do this in case you have a UART DFU bootloader on the nRF52832 chip first. In order to flash this onto the chip too, you will need a debugger.

Regards,
