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
----------------------- Start -----------------------
Try calling PVRSRVConnect with an invalid argument:
PVR:(Error): PVRSRVConnect: Invalid connection. [0, ]
PVR:(Error): PVRSRVConnect: Unable to open connection. [0, ]
 OK

Try calling PVRSRVEnumerateDevices with invalid puiNumDevices:

Here my configuration:
bblayes.conf:
POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
  /path/poky2.1/meta \
  /path/poky2.1/meta-poky \
  /path/meta-ti2 \
  "

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.
