Any more people think that it would be a good idea to create a i.mx233 or i.mx28 sucessor?
Just update it with a more modern core (A7). Keep the integrated PMU.
Any other NXP solutions (for example i.mx6ul) needs a lot of external components that leads to a more expensive product, nearly double price and space than i.mx233/i.mx28 solution.
It would be a real winner for IoT solutions.
