[meta-freescale] [meta-fsl-arm] SabreLite and u-boot-scripts-boundary

[Sébastien Taylor]

I ran into the same issue but was able to get the u-boot-fslc layer to work correctly which is the default when MACHINE=imx6qsabrelite.  Some oddities though are that it stores the environment on the MMC card even though u-boot is stored on SPI for this device, and compared to the nitrogen board you need to use the bottom full size sd slot and not the top side micro-sd slot.  Detecting the mmc card also is highly unreliable and nearly always fails the first time, using run bootcmd twice seems to work around this issue.

As far as phasing out support for sabrelite, what does this mean?  Support in u-boot or yocto or …?
