TMS320F28377S: Serial Flash Programmer checksum error

Hi,

Hope you have used the example from \C2000Ware_X_XX_XX_XX\device_support\f2837xs\examples\cpu1\blinky, FLASH configuration

and used the right options hex2000.exe -boot -sci8 -a -o <file.txt> <file.out> to create the .txt file.

Please modify the blinky linker command file to align sections on 128-bit i.e. use ALIGN(8) instead of ALIGN(4).

Can you try by erasing the flash before you program i.e. use option 2 before using option 1.

Can you try to perform further debug to understand the issue?

Looks like the device did not receive a proper packet from the host PC. You can debug the issue by loading the kernel via JTAG and using the serial flash programmer to communicate the flash application to the kernel while you have JTAG connected.

Use the Visual Studio project for the serial flash programmer and comment out the DownloadKernel() function. Then you can run the kernel and the serial flash programmer which would be sending the flash application.

Hi Krishna,

The problem is solved. But there is an another problem. I am getting the error message like below

ERROR status: VERIFY_ERROR

ERROR Address: 0x0 

Can the solution be the same advices which are given by you ? 

Thanks. 

Hi,

There is a known issue in Shared_Verify.c which will be fixed in next c2000ware release.

If you need it urgent you can update the file with extending miniBuffer from size 4 to 8 and update in other places in the file accordingly.

Please let me know if you need help.

Thanks,

Katta

Hi,

I extended the size of miniBuffer and updated in other places. But still, I am getting the same error after selecting DFU option also after selecting Verify option. Can there be different type error ?

Regards. 

Hi,

Hope you have assigned miniBuffer[4]-miniBuffer[8] and incremented BlockHeader.DestAddr += 0x8 

Please attach your file. I will see if there is any correction needed.

Thanks,

Hi,

I run the application code with "CPU_FLASH" build selection. And the error message changed. Still, I am getting the following message.

ERROR MESSAGE: BLANK_ERROR

ERROR Address: 0x8200 

What can be problem ? I searched on forum but I couldn't see any post about the blank_error.

Regards 

Hi,

Can you erase all the sectors before trying to program? 

There is a way to debug the issue. I have explained it in my first reply.

Thanks,

Katta

Hi Krishna,

When I select the erase option and type "ALL", I am getting the same error message which is like below

ERROR STATUS: BLANK_ERROR

ERROR ADDRESS: 0x8000
