Hi,


Which settings for the "I am trying to increase the number of registers from 42 to 70." in the Platform Designer did you change?


Can you take a screenshot of that?


Also, if you remain to the original the number of registers of 42 does it work as exepected?

Hi,

Thank you for your reply.

If I just keep the code as it is and keeps the registers at 42 it doesn't work if I use the "Assign Base Addresses".

The code still works, but it doesn't have access to the Flash memory.

I guess it is because onchip_flash.csr changes from 0x00109340 to 0x00109338. I would think that a compile would be enough to make the change and everything work. But that is not the case.

Is there something I am missing?
