Looking at the TCP packets, it is trying to download the bin file but for some reason stops relatively early. The bin file is 400KB but it looks like only about 20 or so TCP frames of 1500 bytes are passed before the failure.
I am using HFS.exe as the documentation describes and it starts but just never finishes. I see the HTTP GET issued from my device and a number of TCP packets but not enough of them.
Is there a setting that I missed? Anyone have any idea why it might be failing?
The chip is a ATWINC1500-MR210PB, so according to the datasheet it should have the 4MB of flash that the documentation says it needs to do the OTA update.
