Hello,

I flahed all binaries on esp32 s3 and it does not boot is in boot loop. Esp board is not the problem.

Anybody faced this or have any idea?

Thx

Yes I have had this also, as I am no expert at all on ESP32 I managed to fix this by loading the image to 0x0 position. Thanks to Chat in helping out I used Python ESPtool to load it. First erase flash: esptool.exe --chip esp32 --port COM5 erase_flash, off course use your own COM port esptool.exe --chip esp32 --port COM5 --baud 460800 write_flash -z 0x0 SomfyController.onboard.esp32.bin That did the trick for me loading it to 0x1000 had mine going in boot loop. When rebooted you can connect to the ESPSomfy WiFi access point (default IP 192.168.4.1) to configure WIfi etc. Hope this helps!

On my s3 it does not boot when the power to cc1101 is connected. But with radio disconnected it boots ok. I have not been able to resolve this issue. So I just bought a regular older model esp32 and it's working great. I read somewhere that some esp32-s3 devices may use lower voltage like 1.8v so perhaps that is related? I don't know. I'm ok with my work around.

So I also encountered this problem on an S3, as well as C3 and the ESP32D. Turns out I was flashing the wrong .bin files for these devices. You need to download the zip packages and extract them and then flash that .bin file for the respective chipset and it works a treat. Not sure what the .bin files are that are not zipped up but don't use them they will cause boot loops and issues. I purchased all my chipsets on amazon. Here is a link to the two that are working great so far.

If anyone's still interested in flashing this on a C6, I made a fork specifically for it.
