CCS/TMS320C28346: CCS/TMS320C28346

Part Number: TMS320C28346

Tool/software: Code Composer Studio

Hi,

 

I uses C28346 and CCS3.3.81.6

I can't  use ICE(XDS510LC USB JTAG) to load program when code located in flash.

The XINTF Zone 6 to connect Flash.

I can load program and run succeful originally.

But after moving some code to Flash, code can't run successfully.

(by using #pragma DATA_SECTION("FLASHFW") The section'FLASHFW" is at XINTF Zone 6)

If I use other tool to burn code to flash. It work okay.

Is any better solution to handle this situation?

    Justin,

    Can you check the flash datasheet to see if it uses command sequences for flash functions like ERASE and PROGRAM?

    If it does, you will not be able to load data directly to an external flash device through XINTF using the normal CCS load procedure because the XINTF memory space is treated by CCS as regular memory that does not require special command sequences to write information.

    Instead, you will need to use an application (or custom plugin) to program your C28x binary into the flash device using the command sequences from the datasheet. It sounds like you have a tool that does this.
