I powered the esp32 using 3.3V voltage

Would the people at ESP32 Forum - Index page know more about their product and asking them might get to the root a bit faster?

I have a standard ESP32 board and here is what I do to program it with FTDI adapter

  1. your 3.3V must be good with enough amps , or else ESP wont flash

  2. I keep holding down both EN(sw2 in your case) and BOOT(sw1 in your case) keys, I hit upload button, when the word 'uploading...' shows up, I let go of EN key, while keep holding down the BOOT key, till writing starts...

It works for me all the time

Thanks for your comment. I'll send the same question in that forum. I probably found the solutions on Google. When I try it (and works), I'll update and close this topic

I found some photos on Google about my problem. I'll try to solve it soldering some wires on my esp32 and put them on breadboard. I want to solve this problem bypassing my custom circuit. I'll program the esp32 using an external circuit
