disconnect the magnetometer and see if the ESP starts ok

I removed the magnetometer from the PCB, but the problem remains.

Do you think it could be that the flash is not correctly connected?

I tried it and figured out that the ESP is constantly restarting. The reset cause is 2 which as far as i know stands for reset pin.
