F2808 Flash API Error #24

David Townzen

Other Parts Discussed in Thread: TMS320F2808

I am trying to get the Flash_Erase routine (Flash API V3.02) to work on a TMS320F2808 device, running on a TMDSDOCK2808 Experimenter Kit. I have no problem loading the Flash using the debugger port of the Docking Station; also, I can write individual words into Flash using the Flash_Program API routine. However, when I try to use the Flash_Erase routine, I get the error code 24. I have the Flash API running out of L0SARAM, with interrupts disabled (using DINT instruction). Sometimes I get the Interrupt 19 error trap from SYS/BIOS. I have the latest versions of CCS and SYS/BIOS; are there any compatibility issues with the Flash API?

Still waiting for a reply. Is there any way to duplicate what the debugger port does when it programs the Flash? That seems to work just fine.

Hi David,

I am having the same issue when erasing and programming flash. Flash reads seem to be fine. Again, it is fine with the debugger attached, but goes to where when running flash is loaded to RAM from flash.

Just wondering if you have had any responses?

Thanks,

Bruce

Hi Guys,

I guess you've gone through the following doc:

Hi Gautam,

Yes, I have gone through the steps in that document. The rest of the application runs fine bootloaded from flash. It is just the erasing and programming of flash that raise interrupt 19 (illegal operation).

Any other suggestions?

Regards,

Bruce

Hello Bruce!

This thread about other MCU but maybe one will be useful http://e2e.ti.com/support/microcontrollers/c2000/f/171/t/240863.aspx.

Thanks Igor. Unfortunately that did help either.

I'm going to stop posting to this thread and create a new one that better details what I'm seeing and the different things I've tried so far.

Cheers,

Bruce
