Hello
I have a cheap ST-link that I use heavylly to program STM arm cortex chip.
So my guess is that it should work for this case.
I am following this tutorial:
https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide/flashing-the-bootloader
Here is my current setup:
So my first issue was to find the P1 SWD pinout.
I could not find it in any documentation, I only found a blog article
I follow that connection.
I am not sure if I should plug both ST-link V2 and the dongle.
I tried both of them without success.
I installed the following software:
nRF-Command-Line-Tools_10_12_1_Installer.exe
At first I tried to follow the tutorial but I got the following error:
C:\Program Files (x86)\Nordic Semiconductor\nrf-command-line-tools\bin>nrfjprog -e -f nrf52
ERROR: There is no debugger connected to the PC.
For curiosity I check with ST-Link if something was found ( I know it will not work ) but actually I could see that ST-link see that something is connected on it and of course does not recognized the ARM.
So I believe that my connection could be correct.
I search many post but none seems to have similar issue.
Thanks,
/Eric
