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.

Best regards,

Hi Vidar

Thank you for the quick response, I indeed used TIMER0, which I forgot to change to my application after integrating the SD.
