Since the image for uboot is chip specific, there should not change anything on this, but the uboot image should consider what chip would use.</P><P></P><P>Regards</P><P>Jorge Alcala</P></BODY></HTML> Mon, 03 Jun 2019 17:48:09 GMT https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/How-does-core-clock-affect-uboot-kernel/m-p/919828#M3528 jorge_a_vazquez 2019-06-03T17:48:09Z
