RTC1_IRQHandler(); Error

Question

Hi all, 
 
 I am debugging a program after compiling with no errors using the SDK 15.2.0 on a windows laptop and nRF52840 board. The program was designed to save 8 bytes of data to flash every 50ms for 3 days using fstorage. There should be enough storage on this particular board to allow for this, however I have not had a successful 3 day run yet. The latest bug in the code occurred at "void RTC1_IRQHandler();" in the call stack and about 90 minutes in with an error value of what looks to be 0x00026FC4, which doesn't make sense, at least not to me. I understand this has something to do with the timers, which I use to call the fstorage functions every 50ms. However, as a beginner programmer, I am unable to assess any issues at a lower level. Could someone give some suggestions as to what may be causing this issue? 
 
 Thanks, 
 Jack

Hi Jack 
 It seems like you have been changing quite a few things within the files, and all these additional errors seems to be due to the changes made in the SDK files. This makes it almost impossible for us to find the error, and the project as a whole will get harder to work with. I suggest you go back to where you were. The point where you got consistent errors. 
 After you've done this, please ensure that you've set DEBUG in the preprocessor defines like this: 
 
 right click your project in SEGGER and click Options. 
 Make sure your configurations are set to Common. 
 Click the Preprocessor Definitions. 
 Enter DEBUG into the Preprocessor Definitions, and click OK until you are back to your project.

When this is done, use the unmodified error handler to check what error code you get when encountering the original error. 
 Best regards,

Hi Jack 
 What do you mean with "an error value of what looks to be 0x00026FC4"? This isn't an error present in our SDK as far as I know. Are you getting this error on your laptop? Also, have you done your math correctly here? 8 bytes every 50ms = 160 byte every second. Which means you would fill up the 1 MB Flash in approximately 105 minutes. Do you agree on this? 
 Best regards, 
 Simon
