Example Blinky is running with HardFault

[Curtis]

Hi

I'm trying to build  blinky example (from SDK17.0.2)  to run it on nRF52833DK.

The board is running correctly if I download the hex comes with SDK but failed if download with compiled hex

I use segger to build it and no error is shown

I also tried to change the definition to BOARD_PCA10100 but have no difference.

I guess something wrong in my segger configuration but have no idea about this

thank you

First thing is to find where the Hard Fault is actually happening.

Do you get any debug logs - over RTT or UART ?

Hi

Please note that the pca10056 project is intended for the nRF52840, which has much more RAM and Flash memory, as well as a Cryptocell feature that is used as opposed to the NRF52833. Please try building and running the pca10100 project instead. You should not see this issue there.

Best regards,

Simon

Hi Awneil

It  happened at very beginning even before the 1st function of main()

Hi Simonr

you are right, I use another sample blinky_freertos and there is project for pca10100. it runs correctly
