Signal Connections on MiniProg3 interface: Is anything connected to Pin 6 and 8 inside programmer?

user_485795501 Mar 30, 2018 8:11 AM

I use a KitProg2 and KitProg3 programmers to program BLE modules, and that BLE capsense mouse: The programming hardware connector on the end device (mouse or BLE module has this connection)

My Question is: Is there any signals connected to pin 6 and pin 8 inside the programmer? I want to tie my Debug UART_RX and UART_TX back to these pins on my end application hardware so I have a one connector interface (my target hardware is potted for industrial use so I only want one connector) I can not find any documentation on the MiniProg3 at the hardware circuit level. just user manuals on how to configure an use the programmer. I dont want to sizzle the programmer or sizzle my end hardware if I tied the uart back to pin6 and pin8.

I may have just found the answer: In MiniProg3 manual there is this drawing:

So this tells me MAYBE there is a problem? If I only use SWD on the programmer and do not switch it to JTAG then probably it is OK to tied my debug uart to pin 6 and pin 8. and it appears that pin 6 is SWV or the debug uart so I need to connect my UART_TX to pin6 and UART_RX to pin8 ????

If you are going to use the SWD debugging with the Miniprog3, then you won't be able to use pin 6 for the UART. If you don't care about SWD debugging, then you can probably get away with using the pins 6 and 8 for the UART output/input.

I've been able to run/test my own miniprog3 debugging using only the 5-pin assignment for SWD, so you you won't need the SWV pin unless you want the extra debug functionality and decide to use the 10-pin connection.
