SGX driver code not present

Hi Robert
Sorry to post this here but the Xchange forum has broken my login.

I used the eewiki recipe to build a kernel and to load a sd card. It all works well but when I tried to run the SGX driver installation I dont get the predicted result
Kernel_version = 4.4.3-bone-rt-r5

I ran
./sgx_build_modules.sh
You then instruct:-
Copy ./deploy/GFX_5.01.01.02.tar.gz to BeagleBone/BeagleBone Black and install

I do not have that in any directory. Is there anything special that I am missing?

Regards
Marius

then "./sgx_build_modules.sh" failed...

Initial guess:

missing 32bit lib's, since the switch to gcc-5, i've opted to not
always install the 32bit lib's by default *

sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 zlib1g:i386

./sgx_build_modules.sh

I am on Ubuntu 14.04 64bit. Does that matter?

probally...

When you ran:

./sgx_build_modules.sh

What did it say.. ???

btw, according to my directions:

http://elinux.org/BeagleBoardDebian#SGX_BeagleBone.2FBeagleBone_Black

it's "./sgx_create_package.sh"

the sgx "modules" are pre-built and in the apt repo..

Ok that seem to have doe the trick. Thanks Robert.

I worked from this one https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-SGX
It says ./sgx_build_modules.sh
I did try ./sgx_create_package.sh as well before I posted. It did not work either.

I installed the 32bit libs now and recompiled. Will the 32bit libs cause trouble on the 64bit Ubuntu?

both scripts require the 32bit lib's, it's just the way the *.bin was
packaged....

From the eewiki.net site, we assume you build the kernel, thus you
need to build the modules via 'sgx_build_modules.sh'..

Whereas, from the elinux site you are using everything pre-built, so
you can the modules in the apt repo and thus only use
'sgx_create_package.sh'...

No, just wasted space :wink:

pre-gcc5 the kernel script would have installed them anyways, as the
linaro 4.9 gcc was built for 32bit users too...

Yes I built everything from source so that explains then why it is different.
