Desperate for Help with Pulsivo ESP32 Flashing Issue – invalid header: 0x0000000 & Failed to Communicate with Flash Chip
Posted: Tue Jun 11, 2024 6:15 pm
Hi everyone,
I'm reaching out in desperation as I've been struggling with an issue while trying to flash my ESP32. I've followed multiple troubleshooting guides and tried various solutions, but nothing seems to work.
The Issue:
Whenever I try to flash the ESP32 using esptool.py, I encounter the following errors:
What I've Tried So Far:
Connections:
Red (VCC) to 3V3 (Pin 2)
Black (GND) to GND (Pin 1 or Pin 15)
Green (TXD) to RXD0 (GPIO3, Pin 34)
White (RXD) to TXD0 (GPIO1, Pin 35)
GPIO0 (Pin 25) to GND for boot mode
Entering Bootloader Mode:
Press and hold the BOOT button (GPIO0 low) while pressing and releasing the EN (Enable) button.
Driver Installation:
Installed CP210x Universal Windows Driver v11.3.0.
Flashing Process:
Attempted to erase flash and flash firmware using:bashCopy codeesptool.py --port COM3 erase_flash esptool.py --port COM3 --baud 115200 write_flash -z 0x1000 your_firmware.bin
Power Supply:
Used a powered USB hub to ensure sufficient power.
Added a Capacitor:
Connected a 10 µF Tantalum Capacitor (16V) between the EN pin and GND.
