TMDXIDK5718: Nucleus app boot issue

Part Number: TMDXIDK5718

Hi,

I am working on making the Nucleus image to load and run from SD card, for this I am using the TI SBL boot-loader available under processor_sdk_rtos.

To create the app file from the Nucleus.out file, I am using the AM57xImageGen.bat script file located under scripts folder. Once app file is generated I am copying the app and MLO files to bootable SD card. The SBL is running good but it's stuck at Jumping to user application.

What are the change required in Nucleus RTOS application? Apart from the memory mapping any other modifications required? in memory mapping what are the sections should I include, just changing the RAM location from 0x80000000 to 0x80000400 will be sufficient?

I have tested the Nucleus image which I am using with Lauterbach Trace 32 debugger and it's working, the debugger usually initialize the board with CMM script files(.gel files in case of CCS) and loads and runs the application.

Regards,

Naveen.

  • Hi Naveen,

    Can you re-test your Nucleus image using Lauterbach Trace 32 debugger without the CMM script files. If this is not working, then the problem is in your Nucleus image. Your Nucleus Image (application program) is responsible for initializing the board. If it still works then it is the SBL. From what you described in your post, I think it is the former case.
