I'm tring to copy program and data memory from TMS320f2809 using uniflash and XDS100v2 debug adapter

I can get the program memory to download and upload 0x000 to 0x7FF to a new chip

but the data memory from 0x800 to 0xFFF i can not get to go when i try to verify of program i get

[ERROR] C28xx: File Loader: Verification failed: Memory map prevented reading 0x000800@Program

I've tried different file types when saving memory from the good device but all produce the same error when i try to load them back into uniflash to program the new device

Is there a setting to load data memory back to device or is there a better way to do this copy complete data and program to a new device?

Kasey,

0xE00 to 0xF00 is not valid memory. Can you try up to 0xE00?

Thanks and regards,

I tried bin, hex, txt all the same error

Hi,

So you are able to read and download the memory? You only encounter an error when you try to load the memory onto a new device?

Best Regards,

Hi Kasey,

I've managed to replicate the issue using similar F2808 device, using XDS110 connector. Firstly, I read the device memory from 0x000 to 0x7FF and then load the program using Flash programming setting as Erase, Program, Verify. On pressing the Load Image button, the device memory was loaded back to the device, program load was successful. Then, when trying to press the Verify Image button, the following error shows.

[ERROR] C28xx: File Loader: Verification failed: Values at address 0x00040E@Program do not match Please verify target memory and memory map.

Filetype used was .txt. Is this the screen you see when trying to debug? Is your flash program setting also set to Erase, Program, Verify?

Thanks,

Charles

Kasey,

I'll need some time to confirm what is happening with the Uniflash owners. Will update you tomorrow.

Update:

The owners are out of office at the moment, will update you at the latest response.

In the meantime, are you able to use CCS to see what the contents of the memory location look like? If you could do a memory dump of the affected addresses to see if the locations are readable.

Thanks,

Charles

Kasey,

I understand that the standalone verify might be failing - however since the verify after program is working fine, you should be ok.

Are any passwords programmed in the device causing it to not able to read the secured memories? Even if not, can you try the verify operation after unlocking (with default password values) the device using the Uniflash GUI?

Also, as Charles suggested, did you try to compare the memory dump? Did it match?

Thanks and regards,
Vamsi
