Microsoft buys Express Logic

Microsoft just bought Express Logic, which makes the RTOS ThreadX. This is important because ThreadX is the operating system that runs on the Raspberry Pi VideoCore GPU. I don't think much will change immediately for the Pi, but overall, interesting.

All part of the plan to gain ownership of the IoT market and have all the worlds devices dependent on MS Azure cloud services.

Perhaps soon you won't be able to buy an IoT thing without it using this OS and being tied to Azure. Rather like buying a PC and getting tied to Windows.

Getting youngsters and educators locked in by means of the Raspberry Pi is a bonus.

Could be a good move, with MS's push to open thing up and use and contribute to open source now.

Who knows, it'll certainly be to get used with 'cloud' which is where their money is.

I don't think we have upgraded the threadx version on VC4 in years. So I don't expect this to be any sort of issue.

A LONG time ago we moved from, I think, Nucleus, to ThreadX, so its not impossible to move from one RTOS to another (the vcos abstraction layer was designed to help with that).

Okay, I'm actually curious... what benefits would there be (if any) to upgrading ThreadX, and what benefits were there to move from Nucleus to ThreadX?

None, and I think pricing.

If you cannot beat them, buy them?
Amazon/FreeRTOS, Microsoft/ThreedX.
IoT is getting very interesting.

FreeRTOS is open source?
ThreadX is not?

So Pi's will have MS code inside them from now on ;)
Time will tell if this makes a difference to the IoT market.

Well, we already have Minecraft, so MS is not totally unknown.

ThreadX is closed source.

In fact, Broadcom bought the source code for ThreadX, not sure of the exact agreement, but somewhat more than a licence. So no issues will arise from this. Interesting that ThreadX was actually a new RTOS by the same guy who did Nucleus, who had sold that on to Mentor.

Sorry that’s old old news - just because LTT have finally found it. See https://www.youtube.com/user/tuxreviews ... _polymer=1

Given we know Broadcom have a licence+ for the code maybe it’s time to close the thread?
