[General] esp_ota_begin fails in simple example

[diegoacuna]

Hi, I'm trying to use OTA firmware updates with Amazon FreeRTOS but so far I haven't been able to get it work. When using the esp_ota_begin function, the platform crashes.

System information

• Hardware board: Hardware board: ESP32-WROVER and ESP32-WROOM
• Operating System: Ubuntu 20.04
• Code version: 202107.00-75-g8710a1b23
• Project/Demo: custom

Code/Steps to reproduce the current status

Here you can find a sample application with only the code to run a esp_ota_begin in the board, for reference these are the relevant lines:

const esp_partition_t *next_update_partition = esp_ota_get_next_update_partition(NULL);
  if (next_update_partition == NULL) {
    ESP_LOGE(TAG, "[E] update_from_file: Invalid OTA data partition or no eligible OTA app slot partition was found\n");
    return -1;
  }
  ESP_LOGI(TAG, "[I] update_from_file: Got OTA partition!\n");


  static esp_ota_handle_t handle = 0;
  ESP_LOGI(TAG, "[I] update_from_file: Begin OTA process\n");
  esp_err_t ota_begin_status = esp_ota_begin(next_update_partition, OTA_SIZE_UNKNOWN, &handle); // HERE THE APP CRASHES

and in the logs I get:

Thanks in advance.

Hello @diegoacuna,

I shall ask my colleagues @dachalco and @mahavirj to take a look at this questions.

Thanks for your patience, Aniruddha

[mahavirj]

@diegoacuna What happens if you try the OTA demo that comes with AFR? Do you see similar issue?

[diegoacuna]

@mahavirj I can try that but is not what I need. We need to use the original OTA functions (because of the way we are fetching the firmware to upgrade). Using those functions is this not supported in amazon-freertos?
