hanks! I had been using a computer running Windows 7, and I got no joy with Zadig and st-link v2 on that. However, you just now mentioned Windows 10, so I'll give that a try.
I think the best option for beginners is to use an CMSIS-DAP/DAPLink adapter. Firmware and drivers are open source and there is an integrated serial port.
The ST-Link adapter is initialized with an ST-Link driver by libwdi. If you have luck you can find an old variant.

Is this how to wire up a CMSIS-DAP to the nRF52832?
i.e. it's the same as a j-tag wiring setup, except that you add the serial Rx and Tx lines?

You have to wire SWCLK and SWDIO. In a note of RedBear BLE Nano 2 i have seen, you require DAPLink >1.5 for nRF52832 support. Rx+Tx is not required for programming.
@NeverDie said in Minimalist SAMD21 TQFP32 Pro Mini:
Well, this is bordering on ridiculous. I received the CMSIS-DAP from Adafruit, but there is no windows driver for it. Furthermore, the company that made it (armstart) has apparently gone out of business.
You should see an storage device and an serial device. The serial device windows driver is available at https://developer.mbed.org/handbook/Windows-serial-configuration

Unfortunately, when I try installing that, it says, "The driver could not be installed. No mbed Micronctrollers were found."

That sucks a lot. Try searching for the hardware id you see in windows, maybe you can find some other drivers from other vendors.

Has anyone noticed that a bunch of cheap Chinese "smart bands" use a nrf51822 ?
This opens some new possibilities if used as MySensors actuator !

Yes. There are people working with it. Please read the discussion at github. There are watches with non nordic chips.
https://github.com/sandeepmistry/arduino-nRF5/issues/165
There are a lot of other hardware like the Noke Lock
Or the iStubb 2 with integrated stop up converter (maybe inductor + software) which works with 0.9V.

Fortunately, I just received the J-link segger from aliexpress. When I plug it in, Windows seems to immediately recognize it. However, the problem is that the Arduino IDE doesn't seem to recognize it: it doesn't show up in the IDE port list under the tools menu.I've tried installing each of the Zadig usb drivers, in turn, with no difference.
I tried installing the mbed usb windows driver, but it fails with the same error message as before.
I also tried downloading the segger software pack and installing it. Still fails.
Frustrating!

You have to remove the J-Link software completely. With my old j-link I had to install the J-Link software for Firmwareupdate. After that I removed the J-Link Software and all drivers via "device manager" (module plugged in) and reinstalled the correct driver with zadig (plugin module after starting zadig).

OK, I'll try that. Which of those 4 Zadig usb drivers should I pick?
Open the windows device manager and pull/plug the device and remove all depending drivers with option to uninstall the drivers.

Right. But after that, which of the four do I re-install from Zadig? Or, am I misunderstanding?@NeverDie said in Minimalist SAMD21 TQFP32 Pro Mini:

The CDC and BULK interface. All other are other Hardware.

FWIW, I ran across another example of where someone is using the DK to program an external nRF5 board:
(https://github.com/electronut/ElectronutLabs-bluey/blob/master/nRF52-DK-prog.md)
Unfortunately, that photo is also roughly the extent of their documentation, though they do spell out the pin mapping and tell which Linux commands to use. -

Unfortunately, that photo is also roughly the extent of their documentation, though they do spell out the pin mapping and tell which Linux commands to use.I tried wiring it up as shown in the photos to the Adafruit nRF52832 and doing a programming through the DK and the Arduino IDE, but as you would expect it just programmed the nRF52832 that's on the DK and not the Adafruit. So, either there's a jumper that needs to be set, or different software is required to program an off-board nRF52832.
-
Well, I found this in the user manual of the DK, which sounds quite encouraging:
The nRF52 Development Kit board supports programming and debugging nRF51 and nRF52 devices mounted on external boards. To debug an external board with SEGGER J-Link OB IF, connect to the Debug out connector (P19) with a 10 pin cable. Figure 22: Debug output connector
When the external board is powered, the interface MCU will detect the supply voltage of the board and program/debug the target chip on the external board instead of the on-board nRF52832.
Important: The voltage supported by external debugging/programming is 3.0 V.
You can also use P20 as a debug out connection to program shield mounted targets. For the Debug out header (P19),the Interface MCU will detect the supply voltage on the mounted shield and program/debug the shield target.So, I'll try powering the off-board nrf52832 separately and see if it then works as described.

Success! Got Blink compiled and uploaded to the Adafruit nRF52832 Feather using the nRF52832 DK.
BTW, the adafruit LED works the opposite of the DK LED: on the Adafruit (as with most Arduino's), LOW means OFF, and HIGH means ON. For some reason the DK is the opposite of that.
