Open Source Hardware Linux board with industrial grade -40+125C temperature STMP1-OLinuXino-Lime2 prototype is live


We have progress on this board software. It now boots, we have been fighting the hardware and of course the issue was RTFM in this case RTFE (Errata) where STM well documented thar this chip requires oscillator and will not work with only crystal. We were misleaded by their kit schematic where they made provisions for both crystal and osciallator and being cheap we first bet on the crystal 🙂 .

Anyway after replacing the crystal with oscillator STMP1-OLinuXino-Lime2 got alive and here is the boot log: https://pastebin.com/ev94Jbk0

Our design is quite different from STM demo kit, we use different PMU, PHY HDMI so many things have to be done on the Linux support, but the results so far are very good.

    Congrats. Which is the final variant of the SoC chosen for the industrial version?

    Full part number if possible 🙂
    Thanks!

      this board will be produced with three main SOCs STM32MP151AAAC, STM32MP153AAAC, STM32MP157AAAC, there is fourth option STM32MP157CAAC which is subject to export limitations as contain crypto technology, so we will cover everything STM produces

        LOL I thought crypto wars were long over… Seems I was wrong.
        What fancy crypto tech does that P/N have on board? AES?

        Have you seen, that STM has also introduced variant with 800 MHz base frequency (I think they have letter D instead of C the part number)? So your list does not yet cover all variants. 🐣

        I check these are add recently, the catch is that they have reduced temperature range, I guess A/C letter can do the same if overclocked and used in less temperature range. it would be waste of money to stock all variants which to have almost same features.

    This can be really nice weather station board.

    Good Work. It is good to see Olimex Open Source boards, transparent process.

    If you could provide a variant with WIFI [not USB] with provision to connect Antenna, that would be awesome.

    Does this board support UEXT?

    Can the Arm Cortex useful to program MicroController independently, will they able to control the GPIO pins? This provide real-time GPIO controlling by MicroController.

    Do you have open USB pins [not ports] exposed that can be useful to connect WIFI over USB or 4G LTE over USB or USB to PCI port possibilities?
