Yes, this is especially important issue for SME and one-man-army folks, just like me and you and many other folks here, who directly feels the pain of additional maintenance costs and trust gained or lost :-) > --- My test farm idea --- > NXDART sounds very interesting!

Yes, start small, with what you have, and only what you need, that should give fastest results :-) I am using modern laptop that consumes ~20W of power peak and ~6W idle, rPi0 takes ~5W peak and ~1W idle. But my desktop and build server takes 175W idle and ~300W peak. This is important when machine is about to run 24/7 and build times are not that important (i.e. 20s vs 400s). > --- Cheap STM32H7 --- > The H7 is kinda top of the line so far I know. > I have heard the F7 is compatible "enough".

Yes I have STM32F769I-DISCO board, but in order to have reliable tests for H7 which one can you recommend? Is there one with all possible peripherals in one chip or all of them have different exclusive peripherals? NUCLEO-H755ZI-Q ~38EUR NUCLEO-H753ZI ~46EUR NUCLEO-H723ZG ~38EUR NUCLEO-H7A3ZI-Q ~38EUR In the currently supported boards I can see: stm32h747i-disco ~150EUR stm32h745i-disco ~140EUR nucleo-h745zi (obsoleted by nucleo-h755zi-q) stm32h750b-dk ~$87 linum-stm32h753b ~$28 <- NUCLEO-H753ZI nucleo-h743zi (obsolete) openh743i ~$70 nucleo-h743zi2 (obsoleted by NUCLEO-H753ZI) > --- PR reviews --- > I don't mind reviewing some PRs here and there.

Please keep an eye especially in subjects / boards / MCUs that may affect you. If you can also test and review other PRs that would be great! :-) The best way would be to setup your own automated local build and test farm that works on real world hardware that you care most. > --- Pico USB --- > The Pico does not require you to drag and drop your UF2 binaries. > In case your USB works; you can use the "picotool" from Raspberry pi.

Didn't rPI consider UART control lines to drive boot input just as ESP32 chips does so esptool can reset and switch to bootrom on its own? :-) Another board is cool for playing with the board on its own, but when you have 32 ports / boards, adding debug probe for one board means removing another board to be tested.. also that may cause problems with usb iteration and identification etc. I am looking for a single board-single usb connection and full automation as the ultimate scenario no manual interaction required :-) If you could find a way to do this we could update make flash so full automation is possible on this target :-) Thank you! :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
