SOFTDEVICE: INVALID MEMORY ACCESS with Info = 256

M. David.

Hi

I'm running into this error when enabling the soft device (see title). I've read about the PREGION[0] and that, if the info variant is > 0 it indicates a soft device peripheral register violation. But I can't find out how to match the value of the info parameter: 256 to the peripheral, which is causing this problem.

1. Which is the peripheral in question?

2. How could I find this out by myself?

Best regards

David

    Hi David,

    You can tell which peripheral it is based on the bit position of the info value. 256 means bit number 8 is set (counting from zero) which corresponds to ID 8 (TIMER0) in the Instantiation table.

    TIMER0 is reserved to the Softdevice for internal use, so you need to select another timer instance in your app to avoid this assertion.
