I wish I had known that 2 years ago, I bought a couple rock64's but all I 
could find was armbian, whose kernel had milliseconds of IRQ latency 
times.  Totally unsuitable for running real hardware that may need 
guidance in a 5 microsecond time frame.

My how to questions were asked in order that the answers might get more 
publicity. Unforch instead of answers which would have facilitated that 
progress, but I was told instead to take it to the main list, 

And no one on the main list is even aware there are arm cpus fully 
capable of doing these jobs. And with 2 exceptions, no one has had any 
interest in how I did it. And only one was able to follow my directions 
to a running system.

I am well awsre of that.

I have made the offer, and I wrote it up where anyone with a browser can 
read the blow by blow. According to the logs, I guess this was not the 
list to tell, that readme has been looked at 3 times now in about 2 

Yes, I block the bots who must think I have I have a 50 gigabyte pipe, 
but its ADSL at 10 megaBITs down. So I understandably block the bots so 
that normal folks can get a byte out edgewise. However there are bots 
that think robots.txt does not apply to them, so they get blocked with 
a /8. If you are a customer of such a company to deserve the /8, my 
sympathies, but you are still blocked.  Change your ISP. It really is 
that simple, refuse to support those that ignore the rules.

Such howto questions have been ignored and/or rejected in the past. That 
was the response at the time. If you now have a new broom, I'd be glad 
to help, but what I've done and which still works well, is also out of 
date. Meaning I should probably try and build a 5.something kernel.
But its running well on a 

4.19.71-rt24-v7l+ #1 SMP PREEMPT RT Thu Feb 6 07:09:18 EST 2020 armv7la

kernel for me. Absolute IRQ latency, worst case while running FF to 
browse the web, 50 microseconds, 4 to 12 doing other things, the rp4b 
multitasks well.

I have yet to find anything this kernel above cannot do.
