Yes, both CPUs are compatible. The only difference regarding the
toolchain/platform is that the Cortex-A7 on the MX6UL supports vfp-v4,
while the Cortex-A9 on the older i.MX6 variants only supports vfp-v3.
The generic arm-v7a toolchain will not use the newer vfp version by
default, but it's something to keep in mind. Just don't add vfp-v4 to
the platform toolchain options in the BSP and you should be fine.
Regards,
Lucas
