Yes, it works fine.

I think you meant  "mx28evk_config"

On my board I don't have to press the power button in order to get the
console output.

Please check your MX28EVK settings:

- Boot Mode Select: 1 0 0 1

- JTAG PSWITCH RESET: To the left (reset enabled)

- Battery Source: Down

- Wall 5V: Up

- VDD 5V: To the left (off)

- Hold Button: Down (off)

Also, I have only tested this on a MX28EVK rev.D board.

I haven't tried this yet.
