Hi, Simon:
Most of the SGX test programs including sgx_init_test will not work anymore because we have switched to DRM-based EGL Window Systems.
Have you tried other SGX test programs at the file system?
-
Weston?
-
QT programs ion top of Weston?
-
Without Weston
o
Kmscube
o
/usr/bin/SGX/demos/Raw/
OGLES2ChameleonMan
o
…
Best regards,
Eric

Subject: [meta-ti] BeagleBone Black - ti-sgx-ddk not working on yocto Krogoth, what is missing
Hi,
I'm trying to use sgx driver for EGL application on BeagleBone Black. I build a minimal image to test it and it is not working.
I got this:
root@beaglebone:~# sgx_init_test

Here my configuration:

local.conf:
PACKAGECONFIG_append_pn-qemu-native = " sdl"
PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"
CONF_VERSION = "1"
PREFERRED_PROVIDER_virtual/egl = "ti-sgx-ddk-um"
PREFERRED_PROVIDER_virtual/libgles1 = "ti-sgx-ddk-um"
PREFERRED_PROVIDER_virtual/libgles2 = "ti-sgx-ddk-um"
IMAGE_INSTALL_append_pn-core-image-minimal = " packagegroup-base-vfat packagegroup-base-usbhost dropbear linux-firmware ti-sgx-ddk-km ti-sgx-ddk-um libdrm"

What am I missing?
I try other configurations, like core-image-weston. After "adjusting" mesa so it won't install gbm, weston won't boot and I still get the previous error.
Thank you.
Simon
