TMS570LS1114: After I copy the code from flash to RAM ,how to judge to write successful?

Part Number: TMS570LS1114

Dear expert:

Now,I have successed to copy the data from flash to ram according to the QJ Wang and Chunk,but I fail to load data to CAL_ROM in my main.c ,So I just want to know how to add the calibration information including lots of data .

I load the flash API into the bootloader, CAL_ROM is used to restore important information,So I want to know whether I shuould modify any information in the cmd file?

main()

{

copyflash2ram((char*)api_load,(char*)api_run,(unsigned int)api_size);//Test success

Fapi_FLASH_write(0x00000000,API_flash_read_data,8);

}

Hello Chiqiu,

How do you provide the data to the flash API? i.e., you have copied the API into RAM and make a call to write data but where is the data coming from? Have you included some const data in your object files? If you treat this similar to a boot loader program, you can transfer data into the device over SPI, CAN, UART, etc. The data would need to come into the device in packets and you would need to have a handler/application that would then extract the data from the packet and write to the desired application. Essentially, the data coming in will be binary data similar to if you were reprogramming the device.

Have you reviewed the boot loader application notes to see how this is done?

Each of these include example code that will receive and program data into Flash. The data can be a new image or it can be CAL data as you need.
