Im using esp8266 freeertos sdk. esptool.py v2.4.0.
I already do step from this link "https://www.esp32.com/viewtopic.php?t=1658".
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)
But, im unable to fully suppress all msg during startup. The device still printing as below at baud 74880.
