Hi,
thanks for the answer. This is my kernel config:
developer at ubuntu:~/beaglebone/debian-fw/bb-kernel/KERNEL$ grep
FW_LOADER_USER_HELPER .config
developer at ubuntu:~/beaglebone/debian-fw/bb-kernel/KERNEL$ grep DRM
.config
CONFIG_DRM=y
CONFIG_DRM_KMS_HELPER=y
CONFIG_DRM_LOAD_EDID_FIRMWARE=y
CONFIG_DRM_GEM_CMA_HELPER=y
CONFIG_DRM_KMS_CMA_HELPER=y
# CONFIG_DRM_I2C_CH7006 is not set
# CONFIG_DRM_I2C_SIL164 is not set
CONFIG_DRM_I2C_NXP_TDA998X=y
# CONFIG_DRM_UDL is not set
CONFIG_DRM_TILCDC=y
# CONFIG_DRM_OMAP is not set
I am quite sure that in the end kernel finds firmware because otherwise the
display isn't working. I only get a image on the display if my edid file is
used.
