Engicam MicroGEA STM32MP1 Linux-5.10, U-Boot-2021-01-rc2


Amarula Solutions has partnered with Engicam Srl and started a project to push Engicam SOM’s and Carrier board’s BSP onto Mainline U-Boot, Linux Kernel, Yocto/Buildroot, and Multimedia Open source projects.

We have supported PX30-Core in Mainline as posted before PX30-Core, now we have another project-based STMicroelectronics STM32MP1 SoM, Engicam MicroGEAM STM32MP1

For this specific SoM, Engicam is providing a Capacitive Carrier board and a 7” LVDS interfaced Open Frame board

Now, both these combinations are running Linux-5.10 and U-Boot-2021-01-rc2 and ready to send upstream patches.
