ERROR 1813 [Unknown error code] at KGJ`hóˆ@h:536871936 PC at: 0x0001505C

Hi,

I am using the nRF52840 with nRF-SDK version 16.0.

At random intervals, I encounter the following error:

"[00:02:51.009,460] <error> app: ERROR 1813 [Unknown error code] at KGJ`hh:536871936 PC at: 0x0001505C".

This issue appears to be the same as one previously reported-here, but that ticket did not provide any helpful details.

Could you please explain under what conditions this error occurs? It would help me narrow down the source of the problem in my code.

Thank you,
Shreya

Hi,

Are you using the S140 SoftDevice? If so, the program counter (PC) at 0x0001505C is within the SoftDevice. 536871936 in hex is 0x20000400, which is a valid memory address in RAM (though that should not be the content here). Could it be that the application memory overlaps with the SoftDevice memory? Can you incrase the application RAM start address a bit and see if that makes a difference?
