QNX At the time of this writing, only the 7″ Parallel RGB display is supported in QNX. Known issues There is a known bug in the HDMI driver which causes display corruption if an HDMI monitor is either disconnected and reconnected or powered down and back up during operation. A customer just reminded me of an outstanding bug related to Ubuntu releases and the 7″ display. Biblioteki otechestvennih komponentov dlya diptrace. It appears that something in the startup of X decides to re-configure the display and in the process, bit 17 of the IPU1_DI0_GENERAL register gets cleared to zero.

This bit defines the pixel clock polarity and this will result in visible artifacts on the display.

Hi Eric, I am trying to install Linux on our custom board similar to the I.MX6Q SabreLite board.

I am using linux-imx6-boundary-imx_3.0.35_4.0.0 and linux-imx6-boundary-imx_3.0.35_1.1.1. On the SabreLite HDMI uses I2C2, and on our custom board HDMI uses I2C3. How to move HDMI from I2C2 to I2C3? I am move I2C_BOARD_INFO(“mxc_hdmi_i2c”, 0x50) from static struct i2c_board_info mxc_i2c1_board_info[] __initdata to static struct i2c_board_info mxc_i2c2_board_info[] __initdata in board_mx6q_sabrelite.c What else it is necessary to make? (excuse for my bad English). During u-boot loading time I see the image on the monitor, and during Linux operating time – no. I am looking for some video assistance on a custom i.MX6Q board we have in development.

Currently I have HDMI and LVDS displays connected. When I boot our Ubuntu Linux kernel, only the video source which is attached to mxcfb0 displays the GUI. I can still utilize both displays using gstreamer. Should I be able to use both displays to extend the Ubuntu GUI? If so is the xorg.conf file used to set this up?

Earlier in the boot cycle only the selected display displays the Linux penguins while the other display isn’t even in sync. Once the file system starts to load both displays get in sync. Following is the u-boot environment variables: bootargs=console=ttymxc0,115200 video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24 video=mxcfb1:dev=ldb,1024x600M@60,if=RGB666 If I switch the fb0 and fb1 variables, then the LVDS display works and the HDMI display does not. Is there something within my custom board files that control which display gets enabled? How do I get both displays to work during the early boot cycle? I would expect to see penguins on both displays.
