John, my reference design is OLIMEX EVB, CPU manual and Linux kernel 4.4 EVB has no pullup on the pin PI12, CPU manual has no mention of a possible pullup for the clk_out_a and Linux Kernel does not enable internal pullup
Maybe something can be better documented ? Please, do not be condescending about the "basic physics" on this specific matter Having a pullup wrestle a rising edge on a clock is not equivalent to a standard out pin, if not for accuracy it surely is bad for power consumption Why? It may be that everyone (so far) copies a reference design which had > pullups. > > The 30mA sounds like basic physics.
