Well, for those who are interested - adding pull-up resistor to gpio0 solved the problem. Other circuit elements in my scheme are quite OK, but still theres A LOT to improve

If anything, the FT232 is a 3.3V device so there's no need for the level shifter (?) around VT1/VT2. (I'm not even sure what those circuits are supposed to do, simulating gives me nothing on the output.) But my ft232 module has 5v jumper (mb I misunderstand smth). Anyway I'm going to redesign my bo...

Let's focus on that board then. Schematics would be useful. Also, if you run a standard serial port terminal program on the FT232s COM-port and you turn on the ESP32, do you get anything?

schematics in attachments. If i monitor my board theres a clear terminal

If you're using a devkit, the on-board USB-serial chip already is connected to those pins. Connecting an external FT232 leads to a conflict between those two. yeah, there is cp2102 on my devboard. but I tried to flash a code on my custom pcb and there is the same problem I described above, I can sh...

i'm designing a pcb based on esp32 chip, first i want to test uploading the code with ft232 module, so I took my esp-wroom-32 devkit and ft232 and stuck into a problem - the code is not flashing with error "A fatal error occurred: Failed to connect to ESP32: No serial data received.". my wiring now ...

Hi! I want to use Lora lib in my esp-idf project, I followed instructions of building arduino as a component project but I still have build error. I attach screenshots with error, project tree, etc. Please help! Screenshot from 2023-06-20 16-45-57.png[attachment=0]Screenshot from 2023-06-20 16-47-43...
