TMS570 Flash Load Error with Auto Gen ECC enabled

Other Parts Discussed in Thread: NOWECC, TMS570LS3137

I am using CCS 5.5.0.00077 with Hercules Emulation Tools 5.5.0.5. I get the following error when loading my .out file with the Auto Gen ECC option enabled in the On-Chip Flash settings:

Flash programming. Operation cancelled.

CortexR4: Unable to terminate memory download: (Error -1003 @ 0x2BC5) Internal error: Invalid parameter passed to function. Restart the application. If error persists, please report the error. (Emulation package 5.1.232.0)

CortexR4: GEL: File: C:\Users\name\Projects\Workspace\Debug\test.out: Load failed.

If I disable the Auto Gen ECC option, the .out file loads with no errors. Note: I am not using NowECC or appending any ECC data to the .out prior to loading.

Hi Jeremy,

What exact device are you using?

Thanks

I've also discovered that adding 'fill = 0xFFFFFFFF' to my defined flash sections in the linker command file seems to make the problem go away.

One potential issue is an alignment issue. Would it be possible to try CCSv6.0.1? It has an auto-alignment feature to guard against this.

Thanks

Does your program contain any code which is copied to RAM and executed from RAM?

In this post I created an example which created a similar error when Auto Gen ECC was enabled - but I didn't get any feedback if that was identified as a CCS error.

No I do not have any code that is loaded and run from RAM.

I was able to try CCS 6.0.1 and the problem no longer occurs. It must be the alignment issue that Ki-Soo Lee mentioned.
