You have to apply the following operation to the binary fw file
provided by Freescale.
We agreed with Fabio that they were going to submit that file with the
modification below to the linux-firmware repository soon.
#include <stdio.h>
#include <stdint.h>
#include <assert.h>
#include "vpu_codetable_mx27.h"
int main() {
FILE *f;
uint32_t data;
int i;
f = fopen("v4l-codadx6-imx27.bin", "wb");
assert(f != NULL);
/* Copy full Microcode to Code Buffer allocated on SDRAM */
for (i = 0; i < sizeof(bit_code2) / sizeof(bit_code2[0]); i += 2) {
data = (uint32_t)((bit_code2[i] << 16) | bit_code2[i + 1]);
fwrite(&data, sizeof(data), 1, f);
}
fclose(f);
}
