The i.MX6SL-EVK will need both custom U-Boot and kernel. My message was really for Nitrogen6X customers that might be interested in evaluating the performance of Solo or Dual-Lite CPUs. > I think it did work for your board because Boundary's U-Boot already > handles it however we currently use U-Boot 2013.01 by default here and > this still doesn't cope with the other variants of i.MX6 SoC. > Yep.

We did this by creating "pads-mx6_sabrelite.h" and including it twice: once for Dual/Quad and again for Solo/Dual-Lite: https://github.com/boundarydevices/linux-imx6/blob/boundary-imx_3.0.35_1.1.1/arch/arm/mach-mx6/board-mx6q_sabrelite.c#L124 This allows us to boot all of our SD cards on all of our boards. We even have a boot script for Adeneo's Windows CE7 to make it easy to swap. Regards, Eric
