What are the changes need to be done in Keil uVision for flashing a BLE with ST-Link Debugger?

[Abhimanyu K K]

Sir,

I have one custom MDBT50Q evaluation board and a ST-Link debugger. As the Keil IDE is fully defaulted to J-Link none of the example programs are building and flashing. So please help me to change the settings.

The debugger has no effect on building - so if you have problems building, that is not related to the debugger choice or configuration.

You need to get the build working first before you have anything to download ...

[Abhimanyu K K]

Yes sir. Building is doing perfectly, 0 errors and 0 warnings. But the program is, not flashing. Please show me the settings to be changed when changing the linker to ST-Link debugger.

The preferred suggestion is to buy an nRF52840-DK, the nRF52840-DK have an on-board SEGGER J-Link debug output header that you can use to debug and program external modules or boards. Then you also have a working nRF52840-DK that you know will work out of the box with the SDK examples, and can be used for comparison with your own hardware.

That said, I could find this devzone thread that may be useful to try in the meantime:

Agreed.

The ST-Link is neither intended nor supported for programming Nordic chips (or, in fact, any chips other than STM8/32).

The OB J-Link on the DK will also allow you to use RTT trace, Monitor Mode Debug, etc.
