Everything is just getting weirder. No, I didn't place any special order. I used stock ESP-WROOM-32 sourced from DFRobot (TEL0111). I checked the power rails as you suggested and could not find any glitches. I'm now using 22uF + 4.7uF + 100nF as decoupling. All capacitors are less than 1 cm away fro...

Alright, I checked both things. I've tested with two power supplies, one of them should be able to provide 500mA (LDO from USB) and the other one 2A (external power supply) and both gave the same errors. I also added the 22uF capacitor with no success. I tried changing the flash mode to DOUT, but th...

There is a 4.7uF and a 100nF capacitor on the power rails... I would also add bigger uF value decoupling capacitors following Espressif's reference designs, see ESP32-DevKitC Reference Design . The design contains 22uF and 100nF capacitors for the ESP32 module, not counting 22uF nearby on the outpu...

What power supply are you using? Is it capable of putting out a stable 3.3V at give-or-take half an amp? Thanks for the answer. Yes, It's capable of providing 2A and there seems to be no drop in the rail voltage while programming when checked using an oscilloscope. I'm simply measuring the voltage ...

Hello, We've been developing a solution using ESP32-WROOM modules, however I could only flash the modules randomly. Most (>95%) of the time I've been getting either RAM errors (when using esptool to read the chip_id) or Flash Memory errors (when trying to actually flash it). The board is now populat...
