Is anyone interested in helping to make an Arduino Due which uses [edited:] a 100-pin STM32L471

Sorry I missed it, what is the F030 for?

USB to serial converter I guess.

yehyeh. i also wired it up to the SPI interface as on the F030 that maxes out at 18mbit/sec and the USB interface @ 12. so you could... once the software's written sigh... theoretically upload firmware / files @ around a megabyte per second over that.

maybe st-link, compare with nucleo boards ?

yehyeh, i always got confused, why does that second st-link processor even exist, i always bypass it, wiring up a USB cable to the appropriate pins, directly. then i realised, of course, it has SWDIO etc. wired to it. unfortunately getting SWDIO/CLK across as well on this revision would be too much, even though there's two spare pins on the 030.

so... yeh, a cut-down version of st-link, advantage being it would have software support. i've not used it before though.

the nucleo's show up as 3 interfaces, st-link, memory drag and drop & a serial cdc;
they also show up as pin options in CubeMX or are options in the functionality tree ( left side in pin mode )

There is cmsis-dap, which I understand is open source and similar capabilities to ST-Link.
I have seen it used in some Nucleo clones coming from China, but can't confirm if it provides the exact same capabilities (debugging, serial, mass storage).

Giving the board a built in debug interface would have been another advantage compared to a DUE.
Probably in V2 ?

yehyeh. i just couldn't face another overnighter ripping up around 50 tracks and doing them again by hand (no push/shove or autorouting in eagle 6...). also i'm on a deadline for Shenzhen Maker Faire, which is the 10th-12th next month. i'll likely give it a shot when i've less time pressure.

thx victor i've made a note to investigate cmsis-dap.
