Hi,
I have a problem with the reset pin not working on the nrf52811. The firmware was developed on the nrf52840dk board and now that we are migrating to the real nrf52811 chip the reset won't trigger. Here is the Makefile for the project where we removed the
#CFLAGS += -DBOARD_PCA10056 #CFLAGS += -DDEVELOP_IN_NRF52840 #ASMFLAGS += -DBOARD_PCA10056 #ASMFLAGS += -DDEVELOP_IN_NRF52840 #ASMFLAGS += -DNRFX_COREDEP_DELAY_US_LOOP_CYCLES=3

Here is the schematic of the reset circuit and we measured the point where the red arrow is showing to check if the chip is getting reset. This point pulls low for 2 seconds but that does not reset the chip
System: Ubuntu 18.04. LTS, nRF5_SDK_15.3.0_59ac345
What could be a problem here?
Best regards,
Vojislav.
