Re: Unable to program/Boot loop custom ESP32-C3-MINI board

Hi, sorry for the late answer. Busy days. Yes, by pulling the bootstrapping pins correctly I managed to enter the correct download mode and flash a test sketch. It worked, thank you very much! I won't forget to properly double check the datasheet ever again. I didn't find much on the datasheet about...

Re: Unable to program/Boot loop custom ESP32-C3-MINI board

I mean V2, as in, version two of the board that you're going to make. (Assuming you're going to respin it instead of bodging the corrections in and calling it a day.) Ah yes, I will re-design a correct and improved version. There's nothing in your flash, but if GPIO9 is high, the ESP32 tries to boo...

Re: Unable to program/Boot loop custom ESP32-C3-MINI board

Hi, Your board looks similar to one I've created, the Rust Board . This board uses the embedded USB for flashing and debugging. For the first time, you need to enter into BOOT MODE manually by the GPIO9 to GND (use a pulldown resistor!) and reset the C3. After that, you need to flash and manually r...

Re: Unable to program/Boot loop custom ESP32-C3-MINI board

So, em, the C3 has a built-in USB-to-serial-JTAG converter... you just had to hook up the data lines to GPIO18/19 pins and you would have a completely integrated programmer. May still be worth looking at for V2. And you may need a V2, as the C3 uses GPIO9 to get into download mode, not GPIO0.Try to...

Unable to program/Boot loop custom ESP32-C3-MINI board

Hi everyone, I'm currently tryin to develop a custom board based on the super compact ESP32-C3-MINI-1-N4. This is (or it should be, at least) an improved version of another board of mine, based on ESP32-WROOM-32 that was tested and working. I wanted to make a smaller board, with USB charge functiona...
