is it possible / are there BSP that support MQX alternatively booting
from an SD Card ?
Currently no bootling from SD card.
On our MCF54418 family we can boot from NAND flash.
If you are using a microprocessor with enough memory resources, you can create a FSLMQX image to be a SD Card bootloader that will erase and re-program your FSLMQX application.
is there any example code / project for this purpose?
SW update via SD Card is often announced in the Freescale kinetis leaflets.
So there should already be an out of the box solution.
