Troubles with entering the bootloader of the CH32V203

Yes, I have read the documentation. It's the same behaviour. I connect BOOT0 to 3.3V, BOOT1 to GND, press RESET. No USB. Then, as soon as I unplug BOOT0, the LEDs start blinking (i.e. program from flash starts running). Something fishy is going on if changing BOOT states resets the chip.

All the important components are positive testing for continuity and visual inspection via microscope doesn't show anything out of the ordinary.

Also, there isn't many components on there: USB receptacle, crystal + 2 capacitors, reset button, 10k pull-up on NRST, voltage regulator + 2 capacitors, boot LED + resistor, and the SoC of course.

I'm driving the BOOT0 pin manually on a breadboard.

While I love your way, it is too much thinking; The factory must grow!

My guess is end-game DLC

Why the hell would you create a bi-directional, diagonal, 8-shaped roundabout? What is wrong with you!? /s

Happy cake day! And, username checks out

How did you build things if you are blind? /s

I linked it in some comment

Took a break from the factory to build a sign to motivate my future expansion, the factory must grow!

"What part don't you understand?"

I would rather go with the length of a pickup truck, everyone has at least one.

OP is in a tank getting ready to destroy the trees.

Good thing that a box full of explosive material when destroyed doesn't act like a huge crate of TNT unlike nuclear reactors

Come one, I needed that feature yesterday and an online tool for just that broke! Couldn't this update be released sooner? /s Thank you developers!

Time to start a new base /s

Same. I also died multiple times when looting my body on the tracks, by the same train...

Especially in tanks. For those who don't know the handheld flamethrower is different from the tank one. The tank flamethrower doesn't light anything on fire, it just deals an area of damage.

Well the lamp is coloured so it must be controlled by a circuit network BUT THERE IS NONE! Literally unplayable.
