ESP32 OTA failed saying image is corrupted

Postby sduddell6 » Thu Feb 10, 2022 7:22 am

I'm trying to implement rainmaker based OTA. OTA URL is successfully received from dashboard, but OTA image validation is failing.
Logs below:

Image validation is failing because of below error looks like:

Code: Select all

␛[0;31mE (32559) Dynamic Impl: alloc(16749 bytes) failed, free size: 3598822, internal ram available: 47159, spiram available: 3562963␛[0m
I debugged in the code and found that, it is failing here:

Code: Select all

    esp_buf = mbedtls_calloc(1, SSL_BUF_HEAD_OFFSET_SIZE + buffer_len);
    if (!esp_buf) {
        ESP_LOGE(TAG, "alloc(%d bytes) failed, free size: %d, internal ram available: %d, spiram available: %d", 
        SSL_BUF_HEAD_OFFSET_SIZE + buffer_len, heap_caps_get_free_size((1<<2)),heap_caps_get_free_size(MALLOC_CAP_INTERNAL), heap_caps_get_free_size(MALLOC_CAP_SPIRAM));
        ret = MBEDTLS_ERR_SSL_ALLOC_FAILED;
        goto exit;
    }
To check if memory was available or not , I have added

Code: Select all

heap_caps_get_free_size
, looks like sufficient memory is present in both external and internal memory.
I have also enabled external memory in config, not sure why it is still failing. Any help would be appreciated.
