[in work to solve/pull] nvs_flash_init() let hang up the boot (pinnedToCore) process

[ no hurry! will look after a week here again]


hi

Stumble straight over a problem with
nvs_flash_init ();

It seems the code hangs at this point.
I use the hello world example
It has changed a little
Use on both cores freertos
And have a task pinned on each core.

Here the first part of the code is always the same:

Code: Select all

/* Hello World Example

   This example code is in the Public Domain (or CC0 licensed, at your option.)

   Unless required by applicable law or agreed to in writing, this
   software is distributed on an "AS IS" BASIS, WITHOUT WARRANTIES OR
   CONDITIONS OF ANY KIND, either express or implied.
*/
#include <stdio.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "esp_system.h"
#include "nvs_flash.h"

#define core_0 0
#define core_1 1

void hello_task_core_1(void *pvParameter)
{
	
	while(1){
    printf("Hello world from core:%d!\n", xPortGetCoreID() );
    vTaskDelay(872 / portTICK_PERIOD_MS);
    fflush(stdout);
	} 
}

void hello_task_core_0(void *pvParameter)
{

	while(1) {
    printf("Hello world from core:%d!\n", xPortGetCoreID() );
	vTaskDelay(1323 / portTICK_PERIOD_MS);
    fflush(stdout);
	}
}
And the changed code in the app_main
Is listed in the 5 tests.

have make on each test

-> make erase_flash
-> make clean
-> make -j8 all
-> make flash monitor

uses the last esp-idf ( without the spi pull request )


please have a look:


Test 1: with nvs_flash_init
reboots..

Code: Select all

void app_main()
{
nvs_flash_init();
// printf("printf in app_main [before taskCreate]\n");
xTaskCreatePinnedToCore(&hello_task_core_1, "core1_task", 1024*8, NULL, configMAX_PRIORITIES - 1, NULL, core_1);
xTaskCreatePinnedToCore(&hello_task_core_0, "core0_task", 1024*8, NULL, configMAX_PRIORITIES - 1, NULL, core_0);
// printf("in app_main [after taskCreate]\n");

Hi rudi, thanks for sharing.
we have a fix for this, which should make it into master today.

Re: nvs_flash_init() let hang up the boot (pinnedToCore) process

ESP_Sprite has found a couple of bugs in FreeRTOS scheduler which happen to cause this. I'm not sure why this issue didn't happen before, probably because nvs_flash_init (and the first flash operation) used to be called as part of esp_phy_init before freertos scheduler was started. Now nvs_flash_init happens after the scheduler has started, which is what possibly triggers the bug.
This does indeed only happen in dual core mode.

thank you Ivan, this sounds plausible.
have wounder me for next logical step to search in freertos scheduler too.
thank you jeroen for figure it out!
will change status to solved.

Re: [in work to solve/pull] nvs_flash_init() let hang up the boot (pinnedToCore) process

hi ivan

please, if you get small time on it, can you reply on this? ( no hurry )

runs!

Code: Select all

	nvs_flash_init();
	printf("printf in app_main [before taskCreate]\n");
	xTaskCreatePinnedToCore(&hello_task_core_0, "core1_task", 1024*8, NULL, configMAX_PRIORITIES - 1, NULL, core_0);
	xTaskCreatePinnedToCore(&hello_task_core_1, "core0_task", 1024*8, NULL, configMAX_PRIORITIES - 1, NULL, core_1);
rebooting

Code: Select all

	nvs_flash_init();
	printf("printf in app_main [before taskCreate]\n");
	xTaskCreatePinnedToCore(&hello_task_core_1, "core1_task", 1024*8, NULL, configMAX_PRIORITIES - 1, NULL, core_1);
	xTaskCreatePinnedToCore(&hello_task_core_0, "core0_task", 1024*8, NULL, configMAX_PRIORITIES - 1, NULL, core_0);
it is important how we create the pinned to core task in enumeration
if we create core 1 at first, it hangs
if we create core 0 at first, it runs
