TUSB3210 I2C-EEPROM Issue

I don't know about IAR's settings, but you could remove zero padding from the end of a file with a tool like this:

#include <stdio.h>
#include <stdlib.h>

int main()
{
	FILE *f;
	int size;
	char *buf;

	f = fopen("input.bin", "rb");
	fseek(f, 0, SEEK_END);
	size = ftell(f);
	buf = malloc(size);
	rewind(f);
	fread(buf, 1, size, f);
	fclose(f);

	while (size > 0 && buf[size - 1] == 0)
		size--;

	f = fopen("output.bin", "wb");
	fwrite(buf, 1, size, f);
	fclose(f);
	return 0;
}
