I2C acknowledge bit not sent.

Hello everyone, I am trying to establish I2C communication between 2 microcontrollers. My colleague operates PIC32 as I2C master device and my job is to program ESP32S3 as I2C slave device. In my opinion our problem is synchronization but actually I have no clue. We both have written our codes separ...

Re: ESP32S3wroom1 chip flash error

Quick update. I have borrowed the USBdetector from my friend and tried to look how much current I am supplying during the flashing process. Current readings show absolute zero(attaching photo). Could this still be hardware related issue? Maybe my usb power supply cable is damaged?

Re: ESP32S3wroom1 chip flash error

I have followed your approach and left programmed plugged in and pressed reset button. These are the messages I am getting(*attaching photo). What can we make of this? To my understanding the chip is in SPI boot mode. It is not expecting more download commands. Any ideas?

Re: ESP32S3wroom1 chip flash error

I have tried pressing reset button after I unplugged the programmer, tried to hold the reset button for a couple of secs and then let go, but still the LED wont light up.

Re: ESP32S3wroom1 chip flash error

Thank you for your insight. I have measured the voltage between LM317 output and GND and I am getting 3.29 volts. Tomorrow I am going to order LM1117 and when I get those, changes will be made. Regarding the boot option, when the PlatformIO terminal says connecting I usually press boot and reset at ...
