This was posted 24 hours ago but it only was approved right now. Since then I have solved the issue on the Stretch Imagination Technologies image.
- I updated the kernel using these options: ./update_kernel.sh --ti-channel --lts-4_14 --sgx - I had to install an additional package: apt install libdrm-dev - I had to do a custom GBM library install, outlined here <https://elinux.org/BeagleBoneBlack/SGX_%2B_Qt_EGLFS_%2B_Weston#The_GBM_Library>. Seems not everything was set up correctly as part of the image. After that it started working. Hope this helps someone Does anyone know if there is any work being done for a similar image for Debian Buster and kernel 4.19? On Monday, March 1, 2021 at 11:02:55 AM UTC-5 eb wrote: > Hi all!
