Hello: is there any particular reason why BBB uses two different crystal frequencies, 24 MHz for the CPU and 25 MHz for the Ethernet chip? Can the two be merged into a single 25 MHz frequency? There is a boot mode option of using 25 MHz for the CPU. Why is it not used?
Concerning the 12 MHz clock for the TDA12288, from the TDA12288 data sheet I understand that the OSC_IN on this chip can be driven from a free running oscillator. There is no timing relation between OSC_IN and the LCD data. Therefore, the 12 MHz clock does not need to be driven by the CPU. Is my understanding correct?
