Flashing custom FTDI board (discuss.tchncs.de)
 

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.

Sea level rise is hardly the only problem

Okay, that certainly sounds like damage then. Most capacitors are pretty easy to solder and extremely cheap, you can buy them in small quantities. I would try a repair if you know what value capacitor

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.

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