Hello,
I am working in a Windows 10 environment with the latest SDK 14. I use the Segger IDE and the various support tools from Nordic (nRFGO, nRF Connect, nRF Master Control Panel, etc.
I believe I am in urgent need of help loading a bootloader onto the Adafruit nRF52832 Feather board. My desire is to use the Nordic Development SDKs with the Segger IDE to load/debug programs developed in the Nordic SDK environment directly with the nRF52832 Feather as a custom board when tethered to the nRF52 DK board. I need to do the development in the Nordic IDE environment (Segger IDE) and program the Feather as a "Custom Board".
I have connected the signal lines with the Feather and nRF52 DK board via the SWDIO, SWCLK, GND, VDD/VTG like this post https://devzone.nordicsemi.com/f/nordic ... 3755#53755
- Tether Connection to nRF 52 DK board
When attached like this, I was able to program the Feather but the program does not launch and it is indicated in the Segger IDE that the target is "Not Attached". The SWDIO and SWDCLK lines are active so the DK board is talking to the Feather board. I can see script commands go out to reset the board and start but there is no response/action from the Feather.
If anyone has any idea which bootloader to use from the long list of bootloaders in the SDK please let me know. Or if there is something else I need to do to get the Feather working as a target custom board.
Below is what I get when I "Build and Debug" using the Segger IDE. The small window at the bottom of the screen says "Not Attached" after the load. I believe the load is successful in the target Feather board since the DK board does not is not the target for a "Start Debug" using the small green arrow near the top of the screen (the green start arrow does not show up when I load the Feather). The Feather also does not react anymore to connecting with the USB (I do not really care right now). If I press the reset arrow at the top left of the menu bar, the script in the window sends out a command to reset but the board does not react. I therefore suspect I need a different bootloader. If I find a bootloader, do I use nRFGO to program it?
Thank you in advance for your help.
