We understand you're looking for the stand-alone firmware update packages in order to update your firmware through alternate methods. Unfortunately, we do not provide these firmware binaries to end-users, as this would be considered a privileged/sensitive resource.
If you need these files for a development purpose, we can recommend for you to contact your Sales or Field Representative, as they will be your main resource in this type of scenarios. You may also reach out to our Resource & Design Center.
Thanks for the clarification. I'll go through / evaluate the channels you mentioned.
