No need for 32-bit.
Yes, I've done it, works fine, with one glaring exception all the 64 bit fans refuse to recognize. When called upon to run machinery that demands microsecond responses in order to run that machinery smoothly AND accurately, the increased latency caused by the 64 bits much larger stack frame to be stored, and pulled back into active service when an interrupt from the machine is received, slowing the response to the interrupt from 5 microseconds to 50 or more is not tolleratable. armhf is much faster, and when doing software stepping, which when the step timing has jitter in its timed pulses, very rapidly kills motor torque with increases in the timeing jitter, with a 50 microsecond jitter killing over 75% of a motors usable power. > > Please see either: > https://pete.akeo.ie/2019/07/installing-debian-arm64-on-raspberry-pi.h >tml or > https://www.raspberrypi.org/forums/viewtopic.php?f=50&t=249449&sid=84f >ebcd504e6159355215ff8b8fa6d67 > > Regards, > > /Pete Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
