E (87) flash_parts: partition 0 invalid magic number 0x0, in a new device

[ihouses]

Hello,

I got new ESP32-WROOM-32 modules that I soldered in my prototype PCB. I tried to flash the hello world on that device but I get an partition error that I dont know how to fix.

I flash the same binary in a normal ESP32 development board and everything was working as expected.

Any idea what is the cause?

There are no errors when I flash this new device (I place the log in the last part of the mail)

Well,

I have tried another module from the same batch and it is working, therefore I think is a hardware problem.
But I am still surprised that the flashing doesnt return any error.
