Beaglebone Black EGL Screen rotation

[zir...@gmail.com]

Hi,

Os: Linux beaglebone 4.14.108-ti-r108 #1 SMP PREEMPT Tue Jun 18 05:11:38 UTC 2019 armv7l GNU/Linux
Egl :EGL vendor string: Imagination Technologies
EGL version string: 1.4 build 1.14@3699939 (MAIN)
EGL extensions: EGL_IMG_client_api_ogl EGL_KHR_image EGL_KHR_image_base EGL_KHR_gl_texture_2D_image EGL_KHR_gl_texture_cubemap_image EGL_KHR_gl_renderbuffer_image E
GL_KHR_vg_parent_image EGL_IMG_cl_image EGL_KHR_fence_sync EGL_IMG_context_priority EGL_IMG_hibernate_process EGL_IMG_image_plane_attribs EGL_KHR_surfaceless_contex
t EGL_KHR_wait_sync EGL_KHR_create_context EGL_WL_bind_wayland_display EGL_EXT_image_dma_buf_import
EGL client APIs are: OpenGL_ES
.. and much more

I cannot get over with display going in portrait mode when rendering EGL full screen.

I want to make the change permanent portrait mode.

 echo 1 > /sys/class/graphics/fbcon/rotate_all  

does rotate the fb as text and linux fb mode, but when using the QT on eglfs or EGL app;s like gles1test1 is allways landscape.

Though the

 export QT_QPA_EGLFS_ROTATION=90

does nothing.

Any help would be appreciated.

Just said in the post, if you read it all, it just rotates the fb not the EGL context.
