Tool/software: TI C/C++ Compiler

Hi,

I need to store my data in emulated EEPROM , I am go through the PDF EEPROM Emulation With the TMS320F28xxx DCS.

So , i am using TMS320F28379D may i get example code for that.

Which sector from flash may i use as EEPROM??

Rani,

You can use any sectors for EEPROM emulation.

We don't have an example code for F2837xD.

Please take a look at these posts:

Hi,

Referred the sprab69 , i need to convert this code to my part number TMS320f28379d . What are file i need to change for my part number . Which one constant ?

lib files are given for DSC i think so, what should i do for TMS320F28379D .

Rani,

None of the files are applicable for the F2837xD device. But, the concept is similar if you need to implement it.

Couple of things to keep in mind:

1. To erase/program the flash on F2837xD, you need to use F2837xD Flash API (V1.54). Here is the reference guide link: http://www.ti.com/lit/pdf/spnu629

C2000Ware has an example to depict the flash API usage on this device: \C2000Ware_3_02_00_00\device_support\f2837xd\examples\dual\flash_programming

We also have a flash wiki page: https://processors.wiki.ti.com/index.php/C2000_Flash_FAQ

2. As mentioned in the TRM, please note that flash on this device has ECC. Hence, you need to program ECC along with data. An 8-bit ECC is calculated for every 64-bit aligned data.

Thanks and regards,

Vamsi
