Avoid Early LOG "Pro cpu up" "App cpu up"

[davdav]

Hi,

I have setup on sdkconfig file a DEBUG level for logs in my application.

The first thing I do on my program is

Code: Select all

esp_log_level_set("*", ESP_LOG_NONE);

to stop logging. However I got

Code: Select all

I (416) cpu_start: Pro cpu up.
I (416) cpu_start: Starting app cpu, entry point is 0x40081290
I (402) cpu_start: App cpu up.
I (417) heap_init: Initializing. RAM available for dynamic allocation:
D (422) heap_init: New heap initialised at 0x3ffaff10
I (427) heap_init: At 3FFAFF10 len 000000F0 (0 KiB): DRAM

I (437) heap_init: At 3FFCDC08 len 000123F8 (72 KiB): DRAM
I (442) heap_init: At 3FFE0440 len 00003BC0 (14 KiB): D/IRAM

D (37) intr_alloc: Connected src 24 to int 9 (cpu 0)
I (41) esp_core_dump: Init core dump to UART
I (45) cpu_start: Starting scheduler on PRO CPU.
D (0) intr_alloc: Connected src 25 to int 2 (cpu 1)
I (4) cpu_start: Starting scheduler on APP CPU.
D (66) heap_init: New heap initialised at 0x3ffe0440
D (71) heap_init: New heap initialised at 0x3ffe4350
D (75) intr_alloc: Connected src 16 to int 12 (cpu 0)
D (159) intr_alloc: Connected src 34 to int 13 (cpu 0)
D (160) intr_alloc: Connected src 35 to int 17 (cpu 0)

Those are generated by "cpu_start.c" and other code which are run by ESP32 before calling main program. How can I disable those "ESP_EARLY_LOGx" logs?

Thanks

Unfortunately, I think the only way to disable ESP_EARLY_LOGx calls are to lower your log level in sdkconfig. However this will mean that the rest of your application will also be restricted to the sdkconfig level or below as esp_log_level_set() can only lower the log level and not raise it.

Hello @ESP_Dazz,

I will change the calls "ESP_LOGD" to "ESP_LOGW" in my application and setup a WARNING level in sdkconfig even if it's a pity to lost informations for debugging.

Otherwise, I could modify cpu_start.c (and other files which call that function before main() is started) and remove the ESP_EARLY_LOGx. Is it correct?

Thanks

Im not sure, but did you try to change this option in menuconfig:

Code: Select all

 Bootloader log verbosity (Info)

 Bootloader log verbosity (Info) 

These lines are logged by the app during its early startup code, after control is handed over from the bootloader binary. So the bootloader log level won't change it, unfortunately.
