TMS320F28035: To copy application code from SRAM to flash

Andrea Faietti

Part Number: TMS320F28035
Other Parts Discussed in Thread: C2000WARE

I have a board with 2 microcontrollers, one of which is the TMS320F28035.

The two microcontrollers communicate via SCI.

I must flash the F28035 from a binary image file stored in the other microprocessor.

I understood how to transfer the binary file to the F2035 SRAM (SPRUGO0C / SPRUI10 chapter 2) and I think I understand that later I have to use the flashAPI library to copy the application code in flash.

Do you know of any example code which already exists to do this?

Thank you

Hi Andrea,

There are some examples in C2000ware SDK on Flash API. Please refer to:

Hi Santosh,

Thanks for the reply.

I searched into C2000ware, but found no examples related to my application.

Could you give me an example where an application code is copied / transferred from SRAM to flash?

Thank you.

Andrea

Andrea,

Please take a look at :

C:/c2000/C2000Ware_3_03_00_00/driverlib/f28004x/examples/flash/flashapi_ex2_ldfu.c

This example illustrates how to perform live firmware update. Please take a look at the header of the file which explains the flow.
