ESP32 Forum

I was testing FLASH TOOL and when I clicked start (to get the information from the chip), it appeared on the console that the "CONSOLE_DEBUG_DISABLE eFuse" was burned.

I went to the Datasheet and apparently it does not seem to be anything serious, just that it will not drop LOG's from the bootROM. What can this fuse, now burned, possibly influence my plate? What is it for? And what is this "bootROM" for?

eFuse CONSOLE_DEBUG_DISABLE: disables serial output from the BootROM when set 1.

It disable the rom basic console. No effect on firmware.

Where can I find more information about this bootrom? In the Datasheet there are not many things.

Can I use all features of esp32 yet? Even secure / flash boot?

Yes. The ESP32 has a feature that when it doesn't see any flash, it drops you into a Basic console. We had some issues with it interrupting customers boot sequences, so I think nowadays we disable it in the ATE process. It was half an internal debugging tool, half an easter egg anyway, so it won't affect your ESP32 experience in any way.
