Linker Script and Documents (Cortex-R5 and A53 - Xilinx Zynq® UltraScale+™ MPSoC ZCU102 )

Hello all,

 

So, I am using Vitis IDE to build my Platform Project.

1. I give a name to my Platform Project.

2. I selected my Hardware Specification for zcu102. 

    a. OS: freertos10_xilinx

    b. Processor: psu_cortexr5_0

3. Click finish

4. Build Project

 

Now, to create an Application.

1. File ->New ->Application Project.

2. I select my Platform

3. Give application project name

4. Domain: freertos10_xilinx on psu_cortexr5_0
5. I select FreeRTOS Hello World

6. Build project

Now, I go to the Linker Script: Iscript.ld and see the following.

Now, I think that I can read my atcm memory region if I go from 0x0 to 0x10000 and for btcm memory region from 0x20000 to 0x30000. 

When I try to read this memories with my code I don't get anything. Nothing is in these memory regions. It's all ? ? ? ? for each base address. 

What am I missing? What are the memory region (base address and size) for the ATCM and the BTCM? Is there a specific document for for zcu102? 

 

Thanks.
