Hello all,

Since a couple of days now I'm trying to get SGX running on my
Beagleboard Rev C4 with Ubuntu 11.10. I followed the Instructions on exactly:

the first run of after install worked and after each boot
all SGX modules are loaded (see dmesg on

Then I tested the SGX acceleration with the EvilSkull demo as user
ubuntu (root makes no difference) with the immediate result in a
kernel panic (see

Doing a pvr restart after reboot also leads to panic (see

Here's my Xorg.log:

This try was my last try after many attempts with ubuntu 11.04, I also
tried pre installed Ubuntu Images from
doing "sudo apt-get install libegl1-sgx-omap3 libgles1-sgx-omap3
libgles2-sgx-omap3", that didn't work either.

Does anyone has an idea?



dmesg: on a fresh reboot, before running any demos on my c4..

dmesg: after trying to run a demo, boards locks up...(c4)


Works fine with v3.0.8-x3

fail: v3.1.6-x6
fail: v3.1.0-x3
fail: v3.1.0-rc9 (rebuilt)
fail: v3.1.0-rc8 (rebuilt)
good: v3.0.8-x3

fun: looks like a v3.1 merge/change

Kernel v3.0.8-x3 works!

Thank you!


fail: v3.2.0-x1 (same omap3_l3_app_irq issue)
fail: v3.2.2-x3 (same omap3_l3_app_irq issue)


fail: v3.2.17-x11


Hi fangstar, the easiest way is:

git checkout v3.0.8-x3 -b tmp

And it'll checkout the tag for that version...

But can you actually do a quick favor for me, as i really haven't had time to test my C4's in awhile with this bug.. Please do:

git checkout origin/v3.0.x -b tmp-v3.0.x

and run "./"/etc.. and basicly test "v3.0.42-x4" against this bug to see if it works exactly like v3.0.8-x3..



Hi Robert,

Is it possible to run the v3.0.8-x3 kernel with SGX on Gumstix Overo FE (OMAP3530) with Angstrom?



Ignoring the Overo part, yes linux is linux, so you could run it on Angstrom.. But back to the Overo part, it may or may not work, as that was never a tested target...

Hi Robert,

Negative result with v3.0.8-x3 kernel on Overo FE (OMAP3530-ES3.1)

I just tried running 'sgx_init_test' and it hardlocked the system.
The last output message on the console is:
Misc Info API: Query the SGX features from host driver
<--[hardlock here]

Is there a specific suite of test applications to run through to ensure that the SGX is working?
