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!

nRF52832 does not support JTAG, only SWD interface. SWD does not support daisy-chaining.

I had the same problem: only higher version of SWD support daisy chaing not the one in Nordic chips. You need to use own build SWD multiplexer to programm/debug multiple devices:
