How to port imx8m mini quad evk to dual lite

[Dhevan]

Hi,

     Currently i am using imx8m mini evk board for our development it contains quad code processor.

     Our custom board contains dual lite processor.

     How to properly port imx8m mini(quad) evk to imx8m mini(dual lite) processor ?

     What are the things we needs to change from yocto, uboot, kernel, device tree to work on imx8m mini dual lite ?

Thanks & Regards,

if your design is based on the imx8mm evk, you can use imx8mm evk source code directly, all of yocto bsp is based on the imx8mm evk board, when you build the bsp, you just use the name imx8mm evk to build

Hi @joanxie 

      Thanks for your reply,

          imx8m mini evk board processor - MIMX8MM6DVTLZAA (i.MX 8M Mini Quad)

         Our custom board imx8m mini processor - MIMX8MM3CVTKZAA (i.MX 8M Mini DualLite)

         Because of evk contains quad core and our custom board contains dual core.

         Operating cores no need to modify ?

         Uboot and kernal, device tree code anything needs to modify ?

Thanks & Regards,

uboot should detect what chip you use, you can use the default uboot and kernel first, if you get any issue, pls forward to me, let me double check this
