Subject: signed HDMI firmware in imx8mq image
Date: Wed, 16 Jan 2019 08:48:40 +0000	[thread overview]
Message-ID: <a47578bb-9855-9645-e48b-fc9d3478a173@data-modul.com> (raw)

Every one,

In order to build a Barebox image to boot imx8mq-evk with HDMI, I have tried to
tell Barebox about the embedded signed HDMI firmware, which is necessary for
provided kernel image by NXP.

for this matter, I added the below line into the
arch/arm/boards/nxp-imx8mq-evk/flash-header-imx8mq-evk.imxcfg

  soc imx8mq
  loadaddr 0x007E1000
  dcdofs 0x400
+ signed_hdmi_firmware firmware/imx/signed_hdmi_imx8m.bin

And placed the firmware into the build-directory/firmware/imx


By checking kernel boot message, it seems the HDMI FW is running, but no access
to the HDMI:
[drm:hdmi_phy_init_t28hpc] *ERROR* HDMI mailbox access failed

What should I do more in Barebox to make HDMI accessible by kernel?

Best,
Reyhaneh
