Power Consumption On Custom Hardware

[phipi]

I'm trying to debug a high current issue on a custom board based on the nRF52832. I'm currently loading a modified blinky app (entire main.c included below). On the nRF52DK I'm seeing around 300uA (which still seems kind of high) but on the custom board I'm seeing 8mA with the same firmware is there anything that I need to configure that could be causing this high current?

#include <stdbool.h>
#include <stdint.h>
#include "nrf_delay.h"
#include "boards.h"

/**
 * @brief Function for application main entry.
 */
int main(void)
{
	/* Toggle LEDs. */
	while (true)
	{
	  __WFE();
	  __SEV();
	  __WFE();
	}
}

Was there any resolution for this issue? I am debugging a similar problem on the nRF52840 and it would be great to know what the root cause was in this case.

Please consider creating a separate question with your inquiry. And if you have current consumption issues with custom HW, please consider sharing your schematic (create a private case if the schematics are confidential).
