I am using ESP32-S3-WROOM-1U-N8 module. I am using UART0 to flash the module. I am able to enter into the download mode when I press & hold IO0 pin and press & release CHIP_EN pin, but I am getting following error in my Arduino IDE console ...
ESP-IDF: ESP-IDF has the immediate and obvious benefit of being maintained by Espressif, so it’s most likely to match the ins and outs of the hardware most closely. In my personal anecdotal experience, ESP32 is one of the more buggy platforms on Arduino, so using the ESP-IDF may be ...
Do I need to connect and ground all the GRN ESP32-WROOM pins, or is it enough to just ground one GRN pin</blockquote>While the GND pins are internally connected (meaning it would probably work with one connected), I'd still connect all of them, preferably to a ground plane of your...
