CCS/AM3359: Trouble Writing Memory Block at 0x0 on Page 0 of Length 0x7ff0: (Error -1065 @ 0x3D5A) in debug mode

Part Number: AM3359

Tool/software: Code Composer Studio

Hello Community,

I am trying to integrate PRU firmware with my CCS project. For that I have added the Binary file path in the project linker section and in library linker I have added the command file.

Now, the project is successfully compiling.

But, when I am getting below error while I try to load the binary in the debug mode.

"Trouble Writing Memory Block at 0x0 on Page 0 of Length 0x7ff0: (Error -1065 @ 0x3D5A) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.3.0.00003) "


Please let me know if I am missing something.

Regard,

Hiren Bhuva

    Hiren,

    I am looking at the program memory page (page 0) of the PRU0 core of the AM335x device and I only see a size of 0x2000. From the message above it seems you are trying to load a program of size 0x7ff0. 

    Hope this helps,

    Rafael

    Hi Rafael,

    Thanks for reply,

    I am not trying to load the program in the PRU0 core. I am trying to load in cortexA8 core. But, I have linked the PRU-Dual mac firmware with the application.

    Actually I want to test my application written in cortexA8 core which is using using PRU Dual-Mac firmware reference. So, I have linked the firmware in the Project in the Linker section of the project properties.

    So, at that time I am facing this error.

    Please Let me know if that is the right way to link the PRU firmware with the cortexA8 firmware code to test the cortexA8 firmware.

    Thanks,

    Hiren

    Hiren,

    Please apologize for the delay; in this particular case, us in the tools team will not have much information about the PRU/Cortex A software integration.

    I will have to ask you to post a question on the device forum referencing this one, so you can get more knowledgeable answers. 

    Regards,

    Rafael

    Hi Rafael,

    I have found the solution.

    I need to modify the linker script to support PRU firmware writing.

    Thanks for the support.
