ESP32 How to turn off automatic log of system output
The system defaults to output a lot of logs, you can set the shutdown, only output my own definition of the log.

1. Disabling ROM bootloader output: pull down GPIO15.

2. Disabling 2nd stage bootloader output: make menuconfig, go to "Bootloader config" and set "Bootloader log verbosity" to "No output"

3. Application: make menuconfig, go to "Component config", "Log output", set "Default log verbosity" to "No output".

This should remove all log output.

Thank you. It's trying to set up

How to disable ONLY 2nd stage output? Setting "no output" in menuconfig disable all output, including my code. I tried to set new level (esp_log_level_set("*", ESP_LOG_INFO);) in start of code, but obvious, this doesnt work (spected).


Edit:
Disabling logput in menuconfig and use "#define LOG_LOCAL_LEVEL ESP_LOG_INFO" worked.

2nd stage boot output = OFF
my code output = ON

Hi:
How to close the log(printf/esp_log) in "main.c". I want to change the UART GPIO1 and GPIO3 to IIC SCL and SDA, so uart must be turned off to avoid conflicts.

请问如何在主程序关闭log，不去改动硬件，只做软件修改。需求是需要把UART的GPIO1和GPIO3改为IIC口，所以必须关闭uart，以免冲突。

I have disabled all this setting's but still getting logs. please see following logs.

Rebooting...

How to disable this?

That is not a log, that is a crash dump. 'Easiest' way to get rid of this is to make sure there are no errors in your code but you can also change if this is printed out in menuconfig: iirc components -> esp-32-specific -> panic handler behaviour -> set to 'silent reboot'.

Ok. Thanks.

Helllo, I'm trying to do the same for the esp32C3, instead of pulling down GPIO15, witch one should I pull down?

Hello - just wondering if there is some way to set the panic handler behaviour to "silent reboot" in Arduino framework? is there a register or similar in the ESP32 which controls this output, which can be set or cleared during run time?
