#include <StreamUpdate.h>

Read a binary application image from an input stream and program flash memory.

Read a binary application image from an input stream and program the application image in flash memory. Flash memory will not be modified unless the entire application is received without error.

A reboot is required to run the new application. Before any reboot, the running application should free, close and clean up any items necessary to put the device in a safe state. For example, it would be better to close active TCP or FTP connections rather than just reset so that any connected clients can close normally. If you wish to reboot from a running application you can use the

void ForceReboot() 

function ForceReboot().

Parameters

fd	The File Descriptor to read the input data stream from
