TMS570LC4357: Issue with Parameter Transfer from Flash to RAM using POM Module

Hello,

Our expert for this topic is out of office today, please expect a reply early next week, thanks.

Best Regards,

Hi Emrullah,

Emrullah Dere said:

Here are the addresses we are currently using:

#define OVERLAY_BASE_ADDRESS     0x08003000U 

#define FLASH_BASE_ADDRESS         0x00200000U

I don't see any issues with these addresses.

Could you please send a sample code for verification and debugging at my end?

Hi Jagadish,
Thanks for your response. I used Halcogen library.

#include "HL_pom.h"

//#pragma LOCATION(test_arr,0x00220000)
//const uint8_t test_arr[64U] = {0U};

/** @fn void POM_Region_Config(REGION_CONFIG_t *Reg_Config_Ptr,REGION_t Region_Num)

* @param[in] Reg_Config_Ptr - this will have the prog start address and overlay addresses and size which have to be set in the registers

In the example in the reference manual, on which line do we show the address in the RAM?
