Suppress Boot messages

[Wilberforce]

Hi, how can these boot messages be suppressed?

There was a reference here:
viewtopic.php?t=299#p1306

but that would then turn off all printf output?

Thanks

You can set the log levels to none and use efuse to turn off ROM output.

Bootstrapping GPIO15 to ground will also disable initial output from the ROM bootloader.

How do youdo this? It sounds like this is on a per board basis and can it be undone?

So there is no way to do this in firmware?

Ideally I want to suppress bootloader output, but allow informational debug output.

This does not appear to work for me. I have read GP015 state and it is ready zero with my jumper, but has no affect on boot.

[ESP_igrr]

Could you please paste the output you get with GPIO15 is connected to ground? Thanks.

Ok - there is a difference!

With GPIO15 grounded:

Remaining part comes from the second stage bootloader and the application. You can configure logging level for bootloader in Bootloader config in menuconfig, and for the application — under Component config, Logging.

I had the same problem, the need to suppress boot messages to the terminal. I've found the complete solution. It consists of 3 steps.

1. As mentioned in earlier posts (> 2.5 years ago), strap GPIO15 to ground.

In "make menuconfig"

2. Bootloader config -> Bootloader log verbosity -> (no output)

3. Component config -> Log output -> Default log verbosity (no output)

Not doing any of these steps enables a different set of boot messages. For instance, not strapping GPIO15 to ground enables messages on reboot from deep sleep. The others enable different sets of boot messages.

Hi genius,

Im using ESP8266 freertos sdk. I have done three step to suppress boot msg but Im still unable to suppress fully boot msg. Below is the msg that printed at baudrate 74880.

Thanks in advanced
