i.Core MX8M Mini is an EDIMM SoM based on NXP i.MX8M Mini
from Engicam.
General features:
- NXP i.MX8M Mini
- Up to 2GB LDDR4
- 8/16GB eMMC
- Gigabit Ethernet
- USB 2.0 Host/OTG
- PCIe Gen2 interface
- I2S
- MIPI DSI to LVDS
- rest of i.MX8M Mini features
i.Core MX8M Mini needs to mount on top of Engicam baseboards
for creating complete platform solutions.
Linux dts commit details:
commit <470d6dad5ddd> ("arm64: dts: imx8mm: Add Engicam i.Core MX8M Mini
SoM")
Add support for it.
