backports

Post by zmemw16 » Fri Dec 29, 2017 5:53 pm

the debian linux sites have a backports repo, ok so maybe not quite correct.

so what if anything could be backported from say f4 to f1, f7 to f4 or f7 to f1 ?
maybe something above and beyond sdio/dma etc
something that could be commonized :-)

Hmmmmm...

Well that is an interesting question.

Generally, evolution of code and support libraries are forward evolving as new h/w has new features but old peripherals must be dragged into the new architecture.

Going backwards with code designed from the ground-up for an advanced processor sounds like lots of work! :shock:
Likely the sensor/device that would benefit from the effort would just be supported better natively on the F4 with existing code. The exception would be a commercial implementation where the dekta-cost would become significant with quantity units.

Any examples?

suppose i rewrite it as thinking of 'some bleeding edge you could really, really use saving you masses of time.'

example sdio/spi/dma f4 to f1, i know i asked the question :-)

We had some backports from F4 to F1 (see the SDIO lib).
But it is always difficult as you have to deal with different registers/hardware structure.

as i recall the surprise was not how bad/hard it was, but that it wasn't :D
