AWS freeRtos "failed to provision device certificate error:48"

Question

I am new to AWS IoT and working with STM32L475 Discovery kit board and trying to run the AWS freertos demo for the board based on the AWS getting started guide.I followed all the steps provided in the AWS documentation but encountering the following error.

I had checked the AWS credentials and they are correct. I used the quick connect method to register my board and create the Iot Thing. I also Erased the flash memory before debugging the project thinking that might be causing the issue.

I am using System workbench on windows 10 (64 bit) for the project and Teraterm serial terminal with speed setting 115200

Could anyone please let me know how to resolve this issue? Thanks is advance.

It looks like (from the second and third log messages) your credentials are incorrect.

Quick Connect should provide you with a Credentials.zip file to download. After unzipping it, you should place the aws_clientcredential.h and aws_clientcredential_keys.h files in the demos/include directory of the Amazon FreeRTOS project (replace the same files already in that directory).

it looks like you might not have the "STM" version of the WiFi firmware (There was a recent change to check for that version specifically).

Have you tried updating the firmware using the instructions found under the troubleshooting section here --> the console should say that the version is C3.5.2.5.STM after doing that.

Yes, I updated the firmware as mentioned on the Aws site and the version is C3.5.2.5 – Govind Kalyankar Oct 08 '19 at 05:06
It needs to be C3.5.2.5.STM --> if the .STM is not there it is not the right version of the firmware. – rose Oct 14 '19 at 22:23
Thank you for your help.It was my mistake that I did not read the version name right at first and used C3.5.2.5 instead of the .STM one. I updated the firmware and now it is connected to aws. – Govind Kalyankar Oct 18 '19 at 05:20

Would you please double check that you downloaded the correct firmware from the Inventek website: https://www.inventeksys.com/iwin/firmware/

The one you need to download is the third link marked as "New STM32L4 Discovery kit IoT node (B-L475E-IOT01A) ISM43362-M3G-L44-SPI-C3.5.2.5.STM SPI Firmware (unzip for bin file)". Here is the direct download link for the same: https://www.inventeksys.com/iwin/wp-content/uploads/ISM43362_M3G_L44_SPI_C3.5.2.5.STM_.zip

Note that you do not need to rename any file or change script if you download the correct firmware.

Thanks.
