SK-AM62A-LP: AM62x: How to access the memory of 64KB SRAM in System Memory?

Tool/software:

Hello Dev TI,

Currently, I am working on SK-AM62A-LP board to develop a project which is to read and write from/into system memory (64KB SRAM with ECC) as shown in below figure. 

I already looked at the Technical Reference Manual provided by TI and modify the SRAM memory address into link.cmd file already. But when I run with address modified, there is an error regarding Trouble Writing Memory Block. I attached a screenshoot of MSRAM memory address below. Can you please explain me on this error?

    Are you trying to access the memory from Cortex A core or the R5 cores? For Cortex A core, have you configured the MMU for accessing this memory and for R5 have you setup MPU region to access this memory. Please indicate what software and version you are using. 

    Thanks and Regards,

    Hello Rahul,

    I am trying to access memory from R5 core. Regarding the MPU region setup, I have already set the memory address of MSRAM in the memory system using sysconfig tool. I am currently using SDK+MCU v10.
