GKI_find_buf_start() accesses an uninitialized variable

We have found an issue within WICED Studio 6.6 where GKI_find_buf_start() appears to be accessing an uninitized variable. We noticed that following a soft reset the RAM contents are not zeroed. Therefore GKI_find_buf_start() interpretation of the data leads to unpredicted behavior. The behavior tends to vary with changes to our application code, which is why we say it is unpredictable. However, the behaviour remains the same for each build. For example, in one case we found the BLE would not report the BTM_ENABLED_EVT following init.

Our temporary solution, given that fixing the GKI_find_buf_start() function is not an option (black box), the only solution available was to ensure the data is initialised. The solution is then to write zeros in RAM during the initialisation sequence (_start()), which fixes the issue.

    /* Enable CPU Cycle counting */
    CoreDebug->DEMCR |= CoreDebug_DEMCR_TRCENA_Msk; /* Global Enable for DWT */
    DWT->CYCCNT = 0;                                /* Reset the counter */
    DWT->CTRL |= DWT_CTRL_CYCCNTENA_Msk;            /* Enable cycle counter */

    // Reset whole RAM
    memset((uint8_t *)SRAM1_BASE, 0, SRAM1_SIZE_MAX);
    memset((uint8_t *)SRAM2_BASE, 0, SRAM2_SIZE);

OTA2 Issues with AWS Presigned URL

Solved

I am currently working a project that requires OTA functionality. I am currently at a point where I have increased the sizes of the following buffers to account for the length of presigned URLs:

- WICED_OTA2_HTTP_QUERY_SIZE
- WICED_OTA2_HOST_NAME
- WICED_OTA2_FILE_PATH

Updating via OTA 2 has been tested via a locally hosted web server (non HTTPS) with long (2k) URLs. This works as intended and ensures that the length itself is not resulting in any issues downloading the image.

The device has been loaded with the Starfield signer used to generate the signing information used in the presigned URLs using wiced_tls_init_root_ca_certificates(starfield_cert) prior to initializing OTA2, which should be significant for verifying the URLs. However, when attempting to download via a presigned url, I get the following output (private info redacted):

It seems to me that verification of the presigned URL is failing at some level, but I am struggling to see where. This issue holds true with the standard OTA2 example, with the prementioned buffers increased to accommodate the URL in wiced_ota2_service.h . Wondering if anyone has any ideas here, or any previous experience using AWS presigned URLs on the WICED platform. Any ideas are greatly apprecieated.
