TMS320F28069: Use Flash API from Flash memory

Hi Fujinaka-san,

1. What kind of the problem will be expected if I execute the Flash API function from the Flash memory?

Details are provided in the Flash API guide within C2000ware, directory: C:\ti\c2000\C2000Ware_3_03_00_00\libraries\flash_api\f2806x\docs

See snippet from the doc below to answer your question:

2. It seems my code, which includes the erasing and programing the flash area, is working well even though my Flash API code does not put on the RAM.  What is the reason for this?

The Flash API is located within the F2806x ROM as well, so it might just be running out of ROM. Are you using the Flash API example in C2000ware? The example has a BootROM build config, which is the default config. You can change the build config to SW_API if you want to see the Flash copy to RAM case.

Hello Kevin,

Thanks for your answer.

I confirmed that Flash APIs are in the boot ROM area in the .map file as follows.

abs 003ffebd _Flash2806x_Erase
abs 003ffebb _Flash2806x_Program
abs 003ffedf _Flash2806x_Verify

Is this OK for this case?

Hi Fujinaka-san,

Yes, that looks right. The Flash API functions are stored and will run from those ROM locations.

Best,

Kevin
