In the meantime, I confirmed that this is the problem indeed! I have to enable “thumb” and
then it runs...
Only thing I encountered is that under “linux/config/Config.in.instructions” there is a
line like this:
select ADK_LINUX_KERNEL_THUMB2_KERNEL if ADK_TARGET_OS_LINUX
but I had to disable it because my OS would not boot with the thumb2 instructions. I also
compared with raspbian 9 it’s kernel config and they also do not enable that option.
Thanks everyone!
Best regards,
Tom,

Hi!
Thanks for checking it out.
Yes, the transfer is ok, I verified it with md5sum.
So under “c library configuration” I am using “arm” as the “instruction set”. Now I
changed it to “thumb” and I am now trying to make that boot again. But as a quick test, I
uploaded one of these binaries from the new thumb-based root directory to my old OS and I
get the exact same error… and I also uploaded that very same file to the official raspbian
9 OS and there it runs without problems.
Can you maybe tell if you are also using “thumb” or are using “arm” ?
May I ask, what commit and tasks are you using for your test you just did?
Best regards,
Tom,

So there must be a different explanation.
Can you verify that the file is properly transferred? Because for me on my PI3 I can run
the program to a point where it gives me
./myriad_compile: error while loading shared libraries: libstdc++.so.6: cannot open
shared object file: No such file or directory
which is a later linker loading error.

Hi Tom,
you can not run x86 or amd64 programs on the arm processor natively. You have to compile
it for arm or you will not be able to run it on the RPI.

https://mailman.openadk.org/cgi-bin/mailman/listinfo/dev Hello,
I am using a RPI3 B+ and using openadk successfully with the linux os using 4.14.71
kernel from raspberry pi itself. Now I am trying to run “openvino R5” which is an intel
library that is only available as a precompiled so file for raspbian 9. It works indeed on
raspbian 9.
But when I try to run their example demo file on my system, I get the error:
# ./myriad_compile
mksh: ./myriad_compile: not executable: 32-bit ELF file
So now I want to debug that, but I’m out of ideas on how to proceed.
You can find the package here:
https://drive.google.com/open?id=1QQL343Svovi0ZQ0YewyiMdtt-m6TyHOc
<https://drive.google.com/open?id=1QQL343Svovi0ZQ0YewyiMdtt-m6TyHOc>
just unpack it in the “package” directory to try it out.
So if you have any hints, I would really appreciate it.
I’m using glibc 2.27, with gcc 7.3.0 compiler.
Best regards,
Tom,
