Flashing NRF51822 with STM32 JTAG Board

anre

Hello,

I've been trying to figure out if this board with STM32F103 (www.aliexpress.com/.../2042650923.html

can directly plug into my debug board

(www.aliexpress.com/.../32399375500.html to program the NRF51822.

From what I have read, the JTAG port should plug directly in and work but I am still not too sure.

Can anybody clear this up for me.

Thanks!

    Any debugger which supports SWD should work. Best is to get a proper Segger JLink, but there are CMSIS-DAP debuggers (there's a guy on the list sells one here embeddedsoftdev.blogspot.sg/.../idap-link.html, I haven't tried it), people have used STLINK although it seems they've had to work a bit. There are Segger clones on aliexpress although I wouldn't use one myself because 1) I don't think people should rip off Segger's IP like that and 2) software updates on the JLink side can break them.

    What's important is the thing you pick ships with available tools you can use, not just to load code onto the device, but use as a full debugger. Debugging with printf() and UARTs is such a waste of time when full debug support is available.

    I have a JLink EDU which I use for just about everything, it was worth the investment.
