What tool is available for programming the OTP (on 28335)?

Hi everybody,

I have prepared (and tested in internal RAM) a new bootloader code and it is ready for programing into the OTP. However I cannot find a way to program the OTP, could you please give me a hand on this matter?

thanks

Rafael -

Programming the OTP on 28x devices is the same as programming the Flash (your code is just loaded into OTP via the command linker file instead of Flash).

See the example code files that come with the Custom Bootloader Options via One-Time Programmable Memory application note for an example - SPRAAQ3(http://focus.ti.com/mcu/docs/litabsmultiplefilelist.tsp?sectionId=96&tabId=1502&literatureNumber=spraaq3&docCategoryId=1&familyId=1523)

If desired, you could alsotry programming to Flash first and testing out of Flash before you program to OTP
