TMS570LC4357: FAPI API to access the FLASH Memory in TMS570LC4357

Hi QJ Wang,

If it enters  Fapi_BlockErase API it disconnect the debug and enters to below picture.

FapiReturn = Fapi_BlockErase(0x003E0000, 4);

Please support to resolve this issue.

Hi Santhosh,

Please copy the Flash APIs to RAM.

You can use the following code to copy flash API section to SRAM:

extern unsigned int apiLoadStart;
extern unsigned int apiLoadSize;
extern unsigned int apiRunStart;

main()

{

/* Copy the flash APIs to SRAM*/
memcpy(&apiRunStart, &apiLoadStart, (uint32)&apiLoadSize);

/* Copy the .const section */
//_copyAPI2RAM_(&constLoadStart, &constRunStart, &constLoadSize);
memcpy(&constRunStart, &constLoadStart, (uint32)&constLoadSize);

Hi QJ Wang,

Yes, After copy this above functions I have resolved no matching sections error.

But, After step in to  FapiReturn = Fapi_BlockErase(0x003E0000, 4); function it go to this below error 

This same code in Bootloader is working fine, but not in application. 

I am planning to share some data information to bootloader before entering to bootloader from application. 

So I need to write a data from application to Flash then need to be read in bootloader code.

Can you please suggest me how to implement  in application side to write a data in flash memory 

Thanks in advance.

Hi Santhosh,

Nothing special. You can use the same way as you did in bootloader.
