    John Bukowski
    The portion of the AM3517 datasheet that explains how to route the DDR portion of the PCB is on pages 135-147. My question is: If we had to choose between “T-routing” the control lines OR the address lines, which set should we “T”?

    Dave Pulvermacher
    If my 26MHz signal is oscillating between 0 and 1v, is that enough to drive the uP? VDDSHV = 3.3V. My oscillator is being powered by 1.8v so I expect to be higher but, alas, it isn't. thanks

    What voltage level should an external 32.768kHz oscillator be running at? My confusion stems from the EVM being at 3.3V but the wiki page states 1.8V (see below). If the 32KHz oscillator you choose exceeds the rise/fall time limit, a push-pull output buffer should be used to create a faster...

    Dave Pulvermacher
    I put a switch in to pull POWER_ON (from the TPS650732) low (it is otherwise pulled up to Vsys). I would still like to tie POWER_ON to the AM3517, though, in order to give the 3517 the ability to reset the board. I see on a ref schematic that POWER_ON is going into a GPIO on the 3517. My only concern...
