Conflicting data exists at address 40000000 to 400005b7

It may be my binary, but I thought it's worth reporting just in case.

Here is the output I get when generating for nRF52840:

I also getting the same error for nrf52832

I have the same issue. Looking at the SVD file and the documentation that Nordic Provides, it seems that they have overlapping peripheral registers somehow. See Chapter 10 of https://infocenter.nordicsemi.com/pdf/nRF51_RM_v3.0.pdf

marsfan commented

Yup. Seems that they have different peripherals that have interwoven registers, thus they have the same base address, which is screwing up the script.
