default firmware

Postby davidbeccue » Fri Dec 23, 2022 6:33 pm

When I buy a real of ESP32-S3-MINI-1-N4 processors, is there any default firmware and/or bootloader on this hardware? In particular, I'm wondering if I can load my firmware via OTA or off of SDIO or something besides UART or JTAG for my first time I flash.

No and in fact the flash is loaded with garbage. If you try to boot it, it will repeatedly output "invalid header" messages.
