Re: [Emc-users] Rockpro64 arrived

Bari,

The problem with 4.14 is that the RockPro64 was only added to the list of 
supported processors very recently. So I don’t think that 4.14 has support for 
many of the features of the RockPro64. 

One of the main developers on the Pine64 boards A64, Rock64 and RockPro64 
basically was still working on 4.4.174 until the last couple of weeks and has 
now jumped to 5.0.0. Armbian also went from 4.4 to 5.0.

As mentioned on the dev list before does anyone even read
this stuff?

I would just use this:

I am not an expert in this, so take this suggestion as such, but when I was
setting up an ethereum miner, I needed to make sure I had the right kernel
or the mining software (or GPU drivers or both) would hang.  I would
suggest you look for the existing kernel version and apply the patch for
the kernel you have.  You might have one step afterwards to see which patch
4.19xx or 5.0.7 works for your installed kernel, but at least you'll have a
starting point as to what you have on your system.

What kernel do you have

?
uname -a
Reply:  Linux ASrock1 4.10.0-28-generic (and some other stuff)
32 or 64 bit?  uname -m
64-bit(x86_64)

Good luck and thanks for trying this and sharing, interested to see how it
works out.
Mark

[Emc-users] Rockpro64 arrived

[Alan Condit]

My RockPro64 from Pine64 arrived about a half-hour ago. I have burned a system 
for it and have it booting from  Stretch. 

Next step is to get the development software loaded and try to build a 
preempt-rt kernel. I have the sources both kernel sources and preempt_rt 
patches for both 4.19.31 and 5.0.7. Can anyone give me a hint as to which one 
to try first?

RockPro64 is now in the list of supported processors.  I wonder what that means 
in terms of getting it to run preempt_rt?

It came with a manual, about 32 pages in English but the English is 
obviously very fuzzy. Much meaning is lost in the translation. One 
fellow on youtube says he ordered a Haun Yang and got the YL620-A which 
is the same thing, but they aren't by a heck of a long row of apple 
trees.

But I didn't specifically order a Haun Yang. I did have one ordered thru 
Amazon, but amazon got me PO'd because although I had registered a new 
card number, there was not a way to disable the old one on that page, so 
they declined the prime payment because they tried to use the old, 
stopped card number, but it took them 4 days to tell me. By then since 
it hadn't arrived, I'd went looking on fleabay and found this poor clone 
for 5 bucks less with shipping, so I canceled the amazon order since 
this clone got here a week faster than amazon would have w/o the prime.

You all know me well enough by now that amazon got a call from a rather 
PO'd customer over that. Amazon has left a bad taste in my mouth 
everytime I've tried to deal with them, and my history dates back 5+ 
years.  They write checks with their advertising their ass can't cover 
and I've been sick of their take it or leave it attitude for years. I've 
paid for prime, which is an annual fee I guess, 2 or 3 times, and have 
actually made it work once.  That dual mister kit? Didn't qualify, took 
8 weeks to get here. And IMNSHO they are junk. Far more air leaks out of 
the joints than makes it out the nozzles.

This fellow has I presume given up as he's not made a new video 
describing his success, so I expect he's muddling along like I am.
