Hi,
The i.MX6 DualLite and Solo shares practically all, including the datasheet:
http://www.nxp.com/assets/documents/data/en/data-sheets/IMX6SDLIEC.pdf
Therefore, you could design the hardware and software for any of the two and it should work in both, just considering the performance difference due to the missing core on the Solo.
Hope this will be useful for you.
Best regards!
