Invalid Header: Infinite messages.

[jpragazzo]

Hey guys. First post on the forum

I've been working with the ESP32-C3-WROOM-2, and currently been trying to simply run the program after flashing it. The issue is: It won't work, as i receive multiple messages of "Invalid header" while monitoring the COM3 port.

Output:

Code: Select all

Useful information:
Using the ESP32-C3-WROOM-2, correctly connected to a USB bridge plugged in COM3 port.
Monitoring using MobaXterm.
Method:
- Externally encrypting bootloader, partition table and app using a .bat.
- Utilizing a python script for flashing.
- Flash encryption enabled and Secure Boot V2 enabled. 3v3. Tested usign 80mhz and 40mhz, 4mb flash memory. Partition table offset of 0xD000.

This project has been discontinued five years ago and now is back on track. It surely has some deprecated commands and functions. I've looked into it in detail in the past month, and it should not be critical. If it IS indeed critical, please let us know.
Let me know of any additional info that might be required too!

Thanks!

Hey guys. Solved from reddit after asking there.
Forgot to burn the efuses. Everything correct, but the efuses. Double checked all adresses too, that is a good practice.

Thanks

That link you posted is no longer valid it seems? I would love to look as I've been struggling with this stuff.
