ESP32 Forum

Hello,
I have 2 ESP32-CAMs. The first to the version "Chip is ESP32D0WDQ5 (revision 1)", the second to the Chip is ESP32D0WDQ6 (revision 1) version.
The first one works very well. The second no. The boot starts indefinitely. I am using the Arduino IDE to load the code. Here is what it displays at boot:
rst: 0x3 (SW_RESET), boot: 0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP: 0xee
clk_drv: 0x00, q_drv: 0x00, d_drv: 0x00, cs0_drv: 0x00, hd_drv: 0x00, wp_drv: 0x00

Can you help me please ?
Thanks

From memory, the 5 and 6 indicate the physical package the chip is in; electrically both are identical and should act entirely the same. That suggests your problem is elsewhere.

Thank you.
I close this post. There is indeed an electrical difference between these 2 versions of the chip. In IDE Arduino config, the V6 works with Flash Mode = "DIO" and not with Flash Mode = "QIO". The V5 works with Flash QIO mode. Why ? I don't have the answer.

Hi MikeBee59, i just bought 7 board with chip esp32d0wdq6. Ive tried everything and i saw that you found the answer to my problem. Can you please explain what do you actually didi to the boards? Thank you!
