blinky_freertos fails with DEBUG_NRF enabled

[pathickey]

The blinky_freertos example in the nRF5 SDK 11.0.0, built for the nRF52 (PCA10040) with GCC, appears to work fine right out of the box. However, when I added -DDEBUG_NRF to the CFLAGS (and deleted the duplicate definition of assert_nrf_callback in main.c), one of FreeRTOS's internal assertions triggers inside vTaskStepTick. The failure seems to indicate that the portable code has incorrectly calculated the sleep time until the next tick in xPortSysTickHandler.

Is this a known bug with the nRF5 FreeRTOS port?

I have tried enabling DEBUG_NRF flag and removing the duplicate call in KEIL. It just worked fine. My GCC setup is not working correctly. Are you testing on pure example or have you added your stuff to it?

[pathickey]

This is the pure example code. The only change I made was to append to CFLAGS in the makefile and delete the duplicate assert_nrf_callback. I am using launchpad's arm-gcc 4.8: launchpad.net/.../4.8 here is a recursive diff between a fresh unzip of the SDK and my modifications: gist.github.com/.../bb7478ae3dee9d18ecdd3ef643f6ac22 here is a tar of the _build directory: s3-us-west-1.amazonaws.com/.../build.tar

Looks like I've reported a duplicate of devzone.nordicsemi.com/.../

I did some testing and it seems to work after applying the path.

Hi Pathickey, FYI Radoslaw is the main engineer who worked on this port.
