Out of 512 KB of Flash in the
ATWINC1510, the first sector (of size 4 KB) is used by the WINC for storing the file
information for host file download feature. Which means that a total of 508 KB size
of Flash can be used by application to store the host file.
The feature is only supported in
ATWINC1510 since the ATWINC1500 only has 4 Mbit of Flash memory, which means there
is no space to store a file.
There is no file system and only one
file is stored at a time. When the get file is called again, the previously stored
file is erased and a new file download is initiated.
The WINC OTA firmware download and
the Host OTA file download cannot run concurrently.
The WINC interprets 404 Not
Found error when application attempts to download a broken or dead link
and provides the OTA_STATUS_SERVER_ERROR error status. The WINC
does not interpret any other message for broken link. The WINC downloads the error
message into SPI Flash and indicates Host as file download. It is the application’s
responsibility to check if the file is valid.
