MicroGEA STM32MP1 is a STM32MP157A based Micro SoM.
General features:
- STM32MP157AAC
- Up to 1GB DDR3L-800
- 512MB Nand flash
- I2S
MicroGEA STM32MP1 needs to mount on top of Engicam MicroDev carrier
boards for creating complete platform solutions.
Linux dts commit details:
commit <0be81dfaeaf8> ("ARM: dts: stm32: Add Engicam MicroGEA STM32MP1
SoM")
Add support for it.
