I designed custom esp32 c3 mini board. When I try to program it through Arduino IDE. I can select it and it shows on COM5 (on every usb port it shows COM5, when I plug devboard it shows diffrent COMport), when I click to upload it shows: Could not open COM5, the port doesn't exist
I can program my ...

Re: ESP32 C3 mini not programming
Before use I forced the board to go into the bootloader and then solder it on the board forgot to add IO8 pin on the board, so forcing it again means desoldering module (which I can do, if necessary). There is no RC delay circuit on enable (never needed it).
This is code after which it all broke ...

ESP32 C3 mini not programming
I have a custom esp32 c3 mini board and I was programming it and using it. Suddenly it stopped programming. It always shows on the same COM port, when I try to upload program it gets stuck on "Connecting...", then it shows:
"A fatal error occurred: No serial data received."
Nothing changed between ...

Re: Could not open COM4, the port doesn't exist
It turned out that I I needed to swap D+ and D- lines and it works. Without RC circuit on enable. I needed tho to enter bootloader mode at first power up.

Could not open COM4, the port doesn't exist
I am trying to program "esp32 c3 mini 1". I soldered usb wires directly to module:
IO18 - D-
IO19 - D+
3v3 and enable - 5V wire through 3.3V regulator (with 10uF capacitors on Input and Output)
Gnd - Gnd
When I try to program in Arduino IDE I see a port that the board is connected to, but I get:
