Open source virtuous spiral

Discontinued products Shruthi
#1

4MS have released the firmware (and schematics, but not PCB design files) for their very interesting SMR filter module, under the same MIT open source licence which Olivier uses: see https://github.com/4ms/SMR

Interestingly, they have used Olivier’s clever audio bootloader code to permit firmware updates of their module in the same way that digital MI modules can be updated. That’s a nice example of the virtuous spiral which open sourcing of code facilitates. There is some interesting raw material in the SMR code base, as well.

yes thats so cool :slight_smile:

#3

excellent news :slight_smile:

#4

Great news! THanks for letting me know! This is a good info for my article on open source!

#5

Yeah, that’s nice. Though it must be said the SCM and RCD code has been on github for some 4 years now.

#6

ubiubu, the real game changer here is the bootloader I think. For previous modules (SCM, RCD and QCD), you had to have a special adapter; now it will be as simple as on Olivier’s modules.
Exciting times ahead!

#7

Sure, this now is more officially and formally open source; just mentioned SCM et al because, well, credit where credit is due.

As for the audio bootloader, well, maybe. It’s fairly tangential to things being open source, though.

#8

Well, if it weren’t made available under an open source license, then the bootloader code couldn’t be re-used by 4MS, obviously. But surely the point is that including a reliable, easy-to-use, end-user firmware update facility is a key enabler for creation of an ecosystem of alternative third-party firmware images for your product?
