MicroGEA STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam. 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. Add support for it.

If STM32MP157AAC is soldered onto this board, you should include SoC dtsi here and no into MicroDev 2.0 board. No ? +#include "stm32mp15-pinctrl.dtsi" +#include "stm32mp15xxaa-pinctrl.dtsi" Regards Alex
