Unknown function at 0x00020906

Hello,

I'm flashing custom code onto a nRF52840 based PCB.

I'm using SDK v14.2, SES 4.52.

The board was running fine for a couple of days.

Suddenly when I reflashed to debug, I got the following error: Unknown function at 0x00020906

What might have happened suddenly?

Thanks

    Unknown function in debug mode does not mean any error. It means that the debugger is unable to link the instruction address to the source files. This could be caused for many reason based on how you have compiled your project. If you want to debug the project, make sure that you compile it with debug symbolic links included and with no code optimizations.
