Are there any plans for WICED to support the cortex-m7? I am developing with the SDK v3.7 and don't see any support yet.
I am not aware of any of our partners that are working on Cortex M-7 solutions, but I'm sure several will eventually migrate to the platform.
M3/M4 is predominantly what's supported on WICED, then A9 is what's supported on Linux.
There's additional details on the partner offering here in the IoT Solutions Guide
