We are struggling with an esp32s3 that randomly blocks in bootloader.
After a long power off, the blocking behavior occurs often at its first boot (≈1/5 boots)
And almost never when the CPU is powered off during a short time.
The previous hardware revision is working fine (tested on 50 boards).
On the 2 boards of the new revision, one of our esp has the booting problem.
Do you have any idea how to deal with this problem ? Thank you

Steps we did to reproduce this bug :
- Use an esp32-s3-wroom-1u m0n4
- Reproduced with esp-idf v5.2.1 and v5.1.2
- Use a HelloWorld example from esp-idf v5.2.1 (available here https://github.com/espressif/esp-idf/tr ... ello_world)
- Use a default sdkconfig.

Flash voltage (VDD_SPI) determined by GPIO45 on reset (GPIO45=High: VDD_SPI pin is powered from internal 1.8V LDO
GPIO45=Low or NC: VDD_SPI pin is powered directly from VDD3P3_RTC_IO via resistor Rspi. Typically this voltage is 3.3 V).
Red GPIOs are floating (used for a daugther board, we did not connect it).
All other GPIOs are rooted, mainly to IC.
