eglinfo is not working about meta-mb HOT 7 CLOSED

The issue you are seing is that the sgx kernel module was not loaded: Either because the devicetree did not enable the device or because the module is not built into the kernel. Since everything works fine on my machine I'm gonna have to do some basic trouble-shooting with you:
Are you sure you used the commit from meta-ti that i'm now specifiying in the README.md? During my tests I also flashed the rootfs and definitely removed any pre-existing uEnv.txt. uEnv.txt is optional and Since it is not generated by yocto it is not necessary. Please remove your uEnv.txt beacuase it conflicts with the way I'm handling loading of the dtb files. Make sure that in your /boot directory on the rootfs there is a symbolic link "devicetree.dtb" that points to the dtb-file for the 7" touch screen.

Thanks for the tip. No I ported the 4.9 stuff to the rocko release.
I'm now checking out the commit which you mentioned in the readme, clean all and start a rebuild.

Hi Martin
after a clean build I recreated a new image.
Unfortunately it didn't boot.
Now the only difference could be in creating the image.
I made a script for that.
My partition looks like this:
Disk /dev/sdd: 14.7 GiB, 15811477504 bytes, 30881792 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000

Device Boot Start End Sectors Size Id Type
/dev/sdd1 * 63 144584 144522 70.6M c W95 FAT32 (LBA)
/dev/sdd2 160650 3132674 2972025 1.4G 83 Linux
/dev/sdd3 3148740 4192964 1044225 509.9M 83 Linux

Have you set any variables in the uboot or did you changed the GPIO55?
Any other ideas?
Thanks a lot.

Comparing sizes or checksums won't do any good. The results will vary because the date and sometimes also the name of the machine building it is compiled into the artifacts.

The logs you sent indicate that you still have the wrong version of u-boot. 2013.04 instead of 2017.01.
Please try running "bitbake -c cleansstate virtual/bootloader". Also clean sstate for the rootfs. Then rebuild.

Hi Martin
I have fixed the issue. It was on my side.
The script created a Fat32 boot partition instead of Fat16.
And there was also an old uboot and kernel on the emmc memory.
So the new stuff didn't boot correctly. Now the eglinfo worked correctly.
Now I will try to activate the HDMI port for some small test with QML.

One point is a little bit awkward, why have checked in two times defconfig in the recipes-kernel?
Thanks for your effort.

from meta-mb.

I'm glad you could solve the problem. Hope it works with HDMI. I patched the dts file for HDMI as well but never came around to testing it. Maybe you could share if it is working or not?

from meta-mb.

Keep you informed when I find it out.
Can you explain me why two defconfig in recipes-kernel?
