Hi all, I'm trying to figure out why the below calculation of my main frequencey clock is not correct.
In the below equation: maindiv2 = 28 maindiv1 = 13 prediv = 23 ps = 0 and CONFIG_SYS_CLK_FREQ is 14745600.
but I get 93622108 instead of 265420800. How is this possible?
here is the equation which is what get_FCLK returns:
return (((maindiv2 + 2) * (maindiv1 + 2) * CONFIG_SYS_CLK_FREQ) / ((prediv + 2) * (1 << ps)));
much thanks. --Jr.
