So now I found out that my board doesn't even give a HDMI output on any TV
which is bigger than 32 inches. I have tried forcing different resolutions
but no luck. Its only giving display on a smaller size TV. What do you
think might cause this issue? Is it due to inverted colors?
Thank you

I have tried with latest 4.14 kernel and 4.9 both. Both of these kernels
have the flag added in their tilcdc files. I have tried adding
blue-and-red-wiring = "crossed" in am335x-boneblack.dts and I even tried
adding same in BB-HDMI-TDA998x-00A0.dts overlay. But none of these worked
for me. So

If nothing changed, either the flag might be wrong or you have a kernel version
that doesn’t support the
Hi Jason,
I have tried adding "blue-and-red-wiring = "crossed"" in my device tree,
but it doesn't change anything.
Is there a way I can look up if my display is RGB565 or BGR565?
Thank you

Which just leaves your hdmi switch connection..

I have the schematics and I followed them to come up with the clone.
Everything on the hardware side seems correct but for some reason I get
inverted red and blue.

Yes its not. On clone, the output from NXP TDA19988, is going to a HDMI
switch rather than going to micro HDMI port, and the output from switch
goes to HDMI connector.
Do TDMA pins invert somewhere from micro HDMI port to HDMI cable with
beaglebone?

Hi Robert,
I tested debian-9.6 from the link you provided, and the colors on my clone
board are still inverted.
I tested the same image on beaglebone and the colors were correct.
Please see my log below for the clone:

I am forcing hdmi resolution through uEnv.txt by un-commenting following:
cmdline=coherent_pool=1M net.ifnames=0 quiet video=HDMI-A-1:1024x768@60e
And I think its forcing display to 24bpp and it is inverting blue and red
color.
I can not get a HDMI display without forcing the resolution. Is
I am using 16bit with nxp tda 19988.

Hi All,
I have a beaglebone black clone and on the HDMI output red and blue color
are inverted. I am using debian 9.5 with kernel 4.14.71-ti-r80.
I have tried changing blue-and-red-wiring = "crossed"; in the device tree
and also un-commented "video-ports = <0x234501>;" in this file:
Hi Pro,
I am Beaglebone fan and I am trying to clone a board from _*Beaglebone*_
_*white*_(A6A). I have some questions need your help:
1). From schematic, CAT24C256W (U7) is to store variable mac memory,
do I need to write codes to this EEPROM in u-boot? Can I just download
u-boot.img from
Refer to my answer that I posted to on that other site.
