Hi @djc,

 

What is present at the address 0xFD0C00AC?

Which device are you targeting? Is it custom board or Xilinx Evaluation board?

Try changing linker script to run code from a different location. Please make sure you restart the board to try the code on hardware.

Thanks,
Arpan

Hi @djc,

 

As you are using zcu102, please use the pre-defined platform to check if you are able to program the same.

Regarding the linker script, right click on application and click on the generate linker script and verify the memory you are using. Try with a different memory to see if it works.

If there is a DAP error already, please restart the board.

 

Thanks,
Arpan

Hi @djc,

 

What worked for you? I changed the 'Hardware Platform' as suggested here and restarted the board for any existing DAP errors but I still end up with the Memory read error. Did you take any other steps other than what was suggested here?

Regards

Nikhil
