ESP32-S3R8 - flashing problem
Posted: Mon Dec 23, 2024 3:38 pm
Hello,
I try to flash my board with PlatformIO either with a serial adapter (CP2102) or directly with USB. I get this:
The trace shows the last messages, after this, communication stops. I tried various upload speeds from 19200 - did not help.
GPIO0/3/45/46 are floating if that makes a difference. Enable pin is pulled high with 10K
When I connect to serial I get steady messages:
Any other data I ned to add which could be helpful?
Cheers
JB

When I connect to serial I get steady messages:
Edit: could it be a problem, that there is no FLASH available - only PSRAM?invalid header: 0xffffffff
Any other data I ned to add which could be helpful?
