[BeagleBone Black] tda998x conflict: About error message

When BBB is booted, The following error messages appears.
I want to know what each means and how to solve it.

  1. [ 1.211465] tda998x 0-0070: Error -121 writing to cec:0xff

  2. [ 1.217056] tda998x 0-0070: set_page 000a err -121

  3. [ 1.426092] tda998x 0-0070: failed to read version: -121

  4. [FAILED] Failed to start Raise network interfaces.

Please, help me~


@taek8461, if this is BeagleBone Black with HDMI, it looks like you either have a conflict on the i2c bus with the build-in HDMI encoder. (check your wiring on the header)…


Thank you for your help.

What is the error as below
[FAILED] Failed to start Raise network interfaces

In internet, that message means network error.
After beaglebone black was booted, eth0 worked well.
Why does that message appear?
