Guru Meditation Error while doing http_client_perform

[DawidGurdzinski]

Hi,
I have currently problem with http_client_perform function, when i try to call http_client_perform function i have "Guru Meditation Error: Core 0 panic'ed (Instruction access fault). Exception was unhandled." error.
there is solution to that. I tried disable NEWLIB_NANO_FORMAT but in VS Code extension for esp idf skdconfig file is always generated with enabled NEWLIB_NANO_FORMAT even if i disable it in config.
Below is part of my code for http_client_perform

Code: Untitled.c Select all

_Bool OTA_IsUpdateAvailable(){

    DEBUG_LOG_OTA("Looking for firmware");

    esp_http_client_config_t http_client_config={.url=FIRMWARE_INFO_URL,.event_handler=_http_event_handler};

    DEBUG_LOG_OTA("Creating http client");

    esp_http_client_handle_t client=esp_http_client_init(&http_client_config);

    DEBUG_LOG_OTA("Client perform");

    //DEBUG_LOG_OTA("Firmware%s",http_client_config.url);

    esp_err_t error= esp_http_client_perform(client); 

    if(error==ESP_OK){

        cJSON * json=cJSON_Parse(Otadrv.RCV_Buff);

        if(json==NULL){

            DEBUG_LOG_OTA("Invalid JSON");

        }else{

            cJSON * boot_hash=cJSON_GetObjectItemCaseSensitive(json,"boot_hash");

            cJSON * firmware_hash=cJSON_GetObjectItemCaseSensitive(json,"firmware_hash");

            cJSON * file=cJSON_GetObjectItemCaseSensitive(json,"file");

            DEBUG_LOG_OTA("boot_hash:%s\n",boot_hash->valuestring);

            DEBUG_LOG_OTA("firmware_hash:%s\n",firmware_hash->valuestring);

            DEBUG_LOG_OTA("file:%s\n",file->valuestring);



        }

    }

    esp_http_client_cleanup(client);

    return false;

}

when this part of code is executed i'm connected to wifi.
I'm using esp-idf 5.1.1 version.
Thanks in advance.

Trivial suggestions but is difficult seeing only those few lines of code
Otadrv.RCV_Buff contains the correct answer ?
can you share also _http_event_handler code

if you copied from the client example the event handler HTTP_EVENT_ON_DATA copy RX data with this line

Code: Select all

    memcpy(evt->user_data + output_len, evt->data, copy_len);

You must define in your client config the target buffer adding

Code: Select all

.user_data = Otadrv.RCV_Buff
