Confirm below process info ：
· i.MX 8MQuad
· 4x Arm Cortex-A53 @ 1.5 GHz
· 1 MB L2 cache
· Arm Cortex-M4 @ 266 MHz
Confirm below supported OS info:
Tools & OS support
And check whether we can get datasheet and HW schematics?
And can NXP provide LPDDR4 memory latency and memory bandwidth, L1/L2 cache status, and PCIe throughput, and whether PCIe can work as host device?
The power is together with the board. About the camera module it depend on your need, if you need you can buy it
All the documents and software tool are here i.MX 8M Evaluation Kit | NXP .
Hope this can do help for you.
Have a nice day
