TMS320F28335 : Flash API Flash_Program() aborts during its execution

Shraddha M

Other Parts Discussed in Thread: TMS320F28335

Hello,

We are using Flash28335_API_V210.lib for TMS320F28335 by using CCS V5.5.

While the application is running, we want to write to Sector B (say 50 bytes) by using Flash_Program().

The input parameters(data buffer pointer and flash address) of this function have correct values before entering the function. But the code aborts during execution of this function and no error status is returned to know what is wrong.

This functions executes from ram as instructed in Flash_API_Readme.pdf.

Any suggestions how to go about this issue?

Thanks & Regards,

Shraddha

Can you make sure that there is no interrupt occurs while erasing the sector B?

Yes Maria,

During the execution of these APIs, i have made sure to use DINT; and DRTM; before calling the API and ERTM; and EINT; after that.

Yet the code aborts after these APIs are getting invoked.

Thanks & Regards

Hi Maria,

Do you have any inputs on how to proceed with debugging, if interrupts are already disabled and re-enabled ?

Thanks & Regards

Hello,

Open the Sector B to be watched in the debugger.

After finishing the step of erasing the Sector B, all of the value of Sector B should be 0xFF.

Please make sure sector B is erased well.

Best regards,

Maria

Thank you so much Maria.

The issue was the line of code for 'memcopying' Flash28_API_RunStart, Flash28_API_LoadStart was missing.

Rest everything was in place i.e. declaration of memory sector and sections to be present in RAM in command file, #pragma used to copy functions to SARAM.

When I put this memcpy in main application file, it worked instantly.

Thanks a ton for all the support! :-)
