Hi,
In order to make problem simpler, I set bypass to C674x_0, PRU_0, PRU_1 in target configuration. It goes longer in downloading.
This is a simple hello.c application:
#include <stdio.h>
/*
* hello.c
*/
int main(void) {
printf("Hello World!\n");
return 0;
}
(Please visit the site to view this file)
The linker file is:

What is the problem for a simple hello.c to run? Thanks,
