SDK and Raspberry Pi 3 B+

It's all about the compiled architecture. All these board are using armhf AB for armv7 and armv8 cpu.

So all you need is the standard GCC that comes with the distribution (raspbian, ubuntu mate, ...) for the armhf architecture (which is exactly what you get on all the distribution for all these 32 bit ARM).

I write X2 plugin for all platforms and I compile on whichever of mine (Raspberry Pi 3B+, Odroid XU4, ...) and the binary works on all (it's a .so at the end and it installs and loads on all my ARM test platform without any issue).

So the SDK, once compiled for armv7 (armhf), will work on all of these arm SBC (and all the one using a debian-like distribution).

If you want to discuss this further you can contact me offline as this is more related to compilation and binary format/linking than astronomy :) (English and French are the 2 languages I speak).

Based on the few things I've read about opencl on RAM platforms (32 and 64 bits), the Mali4xx can't do opencl and the minimum (read somewhere) Mali version for opencl would be the Mali6xx.

I have a few arm SBC and they all have Mali4xx ()including my Rock64 Pro).

A good list of ARM SBC can be found there : https://en.wikipedia.org/wiki/Comparison_of_single-board_computers

I agree, The N2 is really new and it'll take a little bit of time to get the lib optimized for it. But it's a great board (I might get one and give my XU4 to a friend :) ).

Chad has no opinions and informations now at this point.

XU4 and N2 are very rare in our market. Especially the N2, expensive, very little information.

BTW, XU4 also have the ARMBian version, I found it yestoday. So I think our SDK should works fine with XU4.

Thanks

Hi Alain,

Really？ I wish he has a Chinese firstname like mine. :

For the SDK version, yes, it should be ARMV8.

For the N2, there is certainly no problem running the camera, but you do need to pay attention to the system. Like the NanoPi M4, if I use their official system, it is too difficult to run the camera. If I use the ARMBian system, then it works fine. Maybe you can try Armbian too: https://www.armbian.com/

Beside, you should test it first with the simplest executable. Like we did before.

Thanks

Chad

Hi Alain,

Yes, we solved in the past, but we think it is not a appropriate way。

Then we find you can follow this way to load the library, then it should works:

#!/usr/bin/env python

from ctypes import *

#EFWlib = cdll.LoadLibrary('./libEFWFilter.so')

EFWlib = CDLL('libudev.so', mode = RTLD_GLOBAL)

EFWlib = CDLL('./libEFWFilter.so', mode = RTLD_GLOBAL)

EFWNum = EFWlib.EFWGetNum()

print "Detect %d efw exist!" % EFWNum

This is our old demo, it also could works. I think you can try it.

Thanks

Chad
