Got my oscilloscope and there was not a clock pulse at all. I have reason to suspect it's a soldering error so I've ordered another 3 prototype boards and I'll give it another shot

Just reset it manually. You have a watchdog connected via a jumper to the EN line of the ESP32, right? Simply ground the ESP32 side of that jumper.

Gotcha, will do when I get the chance

Your schematic itself looks good to me. A few things to check: - Does the chip get 3.3V? - Does the 40MHz oscillator actually oscillate? - Did you cross-connect Tx and Rx to the ESP-Prog? - What happens if you start a terminal on the serial port and manually reset the chip? Can confirm I didn't mix...

I recently designed from the ground up an ESP32 board for use in small model rockets. However, after soldering the boards I have no luck trying to program them, and due to the small QFN package I honestly can't tell if it's a soldering issue or a design issue I can see the green Bridge TX led light ...

Esp-prog. You don't want to use esp32-pico? You wouldn't happen to know which pins connect to which on the ESP-W4WHD? (Just realized the D2WD uses 1.8v on the VDD_SDIO) I can guess all of them except ESP_IO0, which I want to assume is GPIO0, but I may be wrong Manual I'm looking at is linked here: ...

I'm currently planning on using an ESP32-D2WD for a small model rocket telemetry board, hence why I need to use the standalone chip(everything needs to fit in a 10mmx60mm rectangle). I'm just curious what programmer I should use to write to the chip: I have a basic understanding of the software, jus...
