Unable to update firmware WINC1500 19.5.4 or upload SSL certificates

[antellus]

I've gone through the instructions a few times. It seems like the board cannot be updated to 19.5.4. Along with that, I am receiving errors trying to upload a new ssl certificate. I'm guessing all would be Ok to keep using 19.5.2, as long as I can add new certificates.
