where can I find FlashPrg.c which you need to write external loader in Keil ?
I am reading AN333 from Keil
and here is the next step

The FlashPrg.c which comes with Keil is just blank template, it is missing code to initialize, erase, program QSPI
What they say is to get FlashPrg.c from application note’s ZIP file but the ZIP file is nowhere to be found.
It looks like this, the functions are empty in the template:
int Init (unsigned long adr, unsigned long clk, unsigned long fnc) {
/* Add your Code */
return (0);
}
