ST Microelectronic released new interesting device it’s Cortex-A7 and Cortex-M4 in one package. This solves two problems – the connectivity and ample amount of DDR3 memory to run Linux on Cortex-A7 core and the additional co-processor with Cortex-M4 for Real Time tasks. On top of this it’s -40+125C operating temperature and with 10 years supply longevity warranty from ST.
The prices starts around USD 5, which is in same range as Allwinner/Rockchip.
Their top model STM32MP157C has 3D openGL ES2.0 and CAN. There will be finally properly documented Secure boot (we hope 🙂 ):
From recent Twitter post I see than Bootlin already works on Linux support for STM32MP1.
Overall STM32MP1 looks like very promising SOC for Industrial grade Linux computer.

Included GPU is Vivante, which means a Free Software driver for it (etnaviv) is already included in mainline Mesa – according to https://bootlin.com/blog/stm32mp1-system-on-chip-bootlin-member-of-st-partners-program/

…but check also the comments section of referenced Bootlin article – existing etnaviv support might not cover this particular model, but might not take long to have it covered when based on an already mainlined core design.

It’s not only CAN, classic CAN, it has two of the new CAN FD modules, which improves CAN bandwidth a lot.

Definitely a great candidate! I’d go for one, as it seems to be a perfect base for industrial control.

Industrial application without Secure Boot?
Nowadays, Smart Home products have Secure Boot as a bare minimum. For the industrial variant of this board the STM32MP151Cxx is a must.
SecureBoot is not rocket science, since the days of Freescale’s i.MX6 (HAB) it has become a mainstream thing. Feel free to reach out if you need assistance.
STM32MP1-Olinuxino would be a nice hobby board and variant with 151C would be a good industrial SBC.
ps: Tsvetan, I could put you in contact with ST, they could be interested in adding STM32MP1-Olinuxino as a reference OSHW design for their customers. I wish the team best of luck with the development!
