Peripheral example generates a HARD FAULT

maher

Hello, 

I have nrf52DK (nrf52832-PCA10040) and I wanted to test the Peripheral example in the nrf Connect SDK. I have built the project for nrf52DK_nrf52832 and then flashed the code but it gives a hard faults.

I am using nRF Connect SDK v2.02 on Windows machine using nrf52DK (nrf52832-PCA10040-2.1.0)

And this is the build command:
ً
west build --build-dir c:\nordic\periph\peripheral\build c:\nordic\periph\peripheral 
--pristine --board nrf52dk_nrf52832 -- -DNCS_TOOLCHAIN_VERSION:STRING="NONE" 
-DBOARD_ROOT:STRING="c:/nordic/periph/peripheral;c:/nordic/v2.0.2/nrf/boards/arm/nrf52kbd_nrf52832" 
-DCONFIG_DEBUG_OPTIMIZATIONS:STRING="y" -DCONFIG_DEBUG_THREAD_INFO:STRING="y" 
-DCONF_FILE:STRING="c:/nordic/periph/peripheral/prj.conf"
I am really frustrated because I had a lot of issues in building any project, I had tried many solutions to just get the vscode build a nrf connect SDK example!

And then when finally the build is working, the given example does not work! I thought the vendor-provided things should work from the first try without so much hassle.
Best regards,
Ahmed
