Flashing custom FTDI board (discuss.tchncs.de)
submitted 4 weeks ago by [email protected] to c/[email protected]

I'd like to know if anyone has succesfully flashed a board using their own FTDI chip and not a commercial debug probe.

I want to get into using Rust and I have these STM-based boards where I put an FTDI chip on them so I get a convenient USB-port for power and debug and flashing. I'd really like to get some Rust-software running but I've just hit walls so far with flashing the boards. They work fine when using platformio/openocd and C++ but nothing has worked so far for using "cargo embed" even though it seems to find the FTDI chip correctly and start flashing but then times out.

I'd love to know if anyone has a similar setup working or can give tips on what I could try.

Well expecting people to know that exact part from the episode number is expecting a bit much. Being salty about it doesn't help your case. It's just not that funny either.

Does 'hand to mouth' mean it's being sent away and used as soon as it's produced?

This seems really bad. Debris high up is the worst from what I've read as it will decend into the orbits of everything below it. Anything below it is at risk. Debris at lower orbit has less in its path and will more likely just fall down and burn up. This seems so irresponsible.

As always, nothing will happen

By allowing Russia to expand it further provokes the west to use nuclear weapons. Huh, guess we're at a deadlock. I guess Russia could give back what they stole.

No, you can't short the pads. If there's no capacitor there then there likely never was unless you can see obvious damage. Not all components are placed when manufacturing. A picture would help but it could be a decoupling capacitor which has been deemed unnecessary or not required for the model. So it's unlikely to be the issue. It could still be other capacitors that are getting old but it would be the electrolytic ones.

There was one time when I put a mold filled with liquid water in a cold container and made solid water.

Is it all of them?

How do you mean? Like cracking the knuckles or snapping the fingers?

What does that have to do with countries recognising the illegal annexation?

I believe I see a relay, capacitors, diodes and an inductor. Nothing beepy

So it was difficult to detect but it's by radar that they were detected? No other explanation for how they were detected was given.

I'm changing the PTFE in my heatbreak, I didn't realize these seem to be consumables. It started causing blockage.

A guy sent me a piece of PTFE from his Prusa MK3S+ that I could try as i was having trouble finding any PTFE quickly.

I realized I couldn't just cut a piece and put it in, that caused a lot of filament leakage and underextrusion. The end of the PTFE toward the nozzle was a bit jagged and I believe that's where the leakage happened. Now I'm wondering how the heatbreak and nozzle normally interface inside the heatblock, should they be touching? Should the PTFE protrude a bit from the heatbreak so there's a bit of pressure against the nozzle when I screw it in?

I'll sometimes filter based on "most popular" and the result will be that the top item is som expensive thing that makes me wonder if it's really the most popular. It seems obvious that this might just be a way for the store to manipulate buyers. Does anyone have insight into how these work and is there any real function behind them?

This was the last object I worked on before I took a break. I think I got a total of about 8 hours of HaRGB. I used an NEQ6 mount and William Optics Zenithstar 73
