Error code generated with nrf_gpio.h after programming

[jam_stew]

SDK Version: SDK_17.1.0_ddd560

Chip: nrf52820

Board: PAN1781 Evaluation Board

IDE: Segger Embedded Studio for ARM v_5.62

Softdevice: S140

Windows 10

Hello,

I'm currently attempting to test the ble_app_blinky_c program and have it connect to ble_app_blinky. I have reconfigured both programs as per this guide so the RAM and FLASH values matched with my board.

At this stage I have successfully downloaded ble_app_blinky and ble_app_blinky_c to two boards and both compile successfully. However when viewing the activity on the J-LINK RTT viewer it generates the following output (relevant params have been set to debug):

00> <info> app_timer: RTC: initialized.
00>
00> <error> app: ERROR 3735928559 [Unknown error code] at ../../../../../../modules/nrfx/hal/nrf_gpio.h:492
00>
00> PC at: 0x00029935
00>
00> <error> app: End of error report
00>

After searching online I'm at a loss as to what to do about this error as I haven't encountered it before, and it doesn't seem too well discussed. Any help would be appreciated.

Note: I've also attached the full project as a zip file. The pca10100e folder is the new migrated version

Hi Susheel I am getting the exact same error anytime I run my application in debug mode: <error> app: ERROR 3735928559 [Unknown error code] at C:/nRF5_SDK_17.1.0_ddde560/modules/nrfx/hal/nrf_gpio.h:492
PC at: 0x00038B67
<error> app: End of error report

I never saw an actual resolution posted here so thought I would inquire as to what was changed that resolved the issue? 

Thank you

Matt

I tried the example attached from jam_stew and it worked fine for me, so I did not investigate it further. 

Are you using the example from us out of the box (not changing anything) and still see this error? Is this a customer hardware?

[mjconnor57]

This is a custom application we are developing at my company for a customer, a custom consumer electronics application based on the NRF8240 in a laird module. We actually inherited this project that was started by someone else, I believe they used 1 of the BLE example applications as their starting point. I was able to develop for months in debug without issue, but over the past few weeks I can only use Release or else I run into this fault.

This is one of the systems of stack overflow, What is the RAM usage of your application? have you benchmarked it? in anycase, this seems to be a bit different environment that you have compared to this case (even though the symptoms looks same) .

I would suggest you to create a new thread and investigate it from there. Please give as many details as possible in case we need to replicate this at our desk. If I were you , I would first try to replicate this on our nRF52840 DK to exclude suspicions on the custom hardware.
