I have made a custom board using ESP32-D0WD-V3. Since this model needs an external FLASH memmory, I have chosen the 16Mbit MX25V16066M2I02 from Macronix. I am being able to flash it with my firmware, but it seens that the ESP32 is unable to recognize the memmory during its boot. In the same PCB, I have tested other memories, like the W25Q16JVSNIQ from Wirebond, which worked fine. So, the problem doesn't seen to be related to the PCB design/schematic. Could someone help?
