Maybe I'm ruining the joke, but... Did you notice the 10 Ohms resistor connected parallel to the diode?

Great! Safety is kinda important right?
Have a nice day. (And peace of mind)

again. With the increased temperature, you've put more thermal power in your board than your soldering iron can deliver. Hope this helps.

Not to be that guy. But please consider the safety aspects. Your soldering isn't fully flowed through. That can result in increased resistance and with a high current, a lot of heat. Maybe fire.
You could "pre-heat" your board with a hairdryer or a convection oven. Get it hot (80°C to 100°C) and try

Heb je toevallig ook een ESP32 liggen?

Hmm.. I'm now looking at the software. You're right. It doesn't support passive sniffing, but I can do a "SPI Trace". So that way you can sniff, but the emulator has to be the target. Sorry, my mistake. But if your intended target has a serial flash, then you can use the emulator in its place.

I know about a piece of hardware (that does more). Bit pricey, though: Dediprog EM100Pro-G3. I've picked up an older version from eBay. But that doesn't support QSPI.
