[SOLVED]Load spiffs_image.img after OTA

[Ritesh]

Hello,

Thanks you Ritesh for your help. Finally I resolved the problem. It was always writing at the beginning of the partition. I had to implement a offset because my buffer was 1Kb.

Code: Select all

int offset=0;
    /*deal with all receive packet*/
    while (1) {
        int data_read = esp_http_client_read(client, ota_write_data, BUFFSIZE);
        if (data_read < 0) {
            ESP_LOGE(TAG, "Error: SSL data read error");
            http_cleanup(client);
            task_fatal_error();
        } else if (data_read > 0) {
            /* 3 : WRITE SPIFFS PARTITION */
            err= esp_partition_write(spiffs_partition,offset,(const void *)ota_write_data, data_read);
            
            if (err != ESP_OK) {
                http_cleanup(client);
                task_fatal_error();
            }
            offset=offset+1024;

Great work. Thanks again for your effort to resolve that issue.

Code: Select all

esp_partition_write(spiffs_partition,offset,(const void *)ota_write_data, data_read);

You write length data_read

So

Code: Select all

offset += data_read

Thank you for this post. I needed to update SPIFFS from OTA and I managed to do it thanks to you.

You may find the code for Arduino IDE below. I took most of code form this post to make it.

For me it works great. Bye!
