HI,
1. I disabled VBI channel.
2. I cannot find out memcpy_neon.S in DVRRDK_4.00.03.
But I google this keyword, I can find memcpy_neon.s in https://github.com/genesi/imx-libc-neon/blob/master/memcpy-neon.S. I used this file to rewrite cpu busy loop as below
==================================================================
#include <stdint.h>
#include <stdio.h>
#include <string.h>
#include <time.h>
#include <stdlib.h>
void *memcpy_neon(void *, const void *, size_t);
//void *memcpy_arm(void *, const void *, size_t);
int main(int argc, char *argv[])
{
unsigned char src[1024],dest[1024];
memset(src,0xAA,1024);
while(1)
{
memcpy_neon(dest,src,1024);
}
}
======================================================================
