AT91FR40162S Preliminary
Note that in the event that the Flash Memory Uploader is erased from the first sector while the
new final application is not yet programmed, and while the target system power supply is
switched off, it leads to a non-recoverable error and the AT91FR40162S cannot be re-pro-
grammed by using the Flash Memory Uploader.

Programming System
Atmel provides a free Host Loader that runs on an IBM
®
compatible PC under Windows95,
Windows98 or Windows2000 operating system. It can be downloaded from the Atmel Web site
and requires only a serial cable to connect the Host to the Target.
Communications can be selected on either COM1 or COM2 and the serial link speed is limited to
115200 bauds. Because the serial link is the bottleneck in this configuration, the Flash program-
ming lasts 110 seconds per Mbyte.
Reduced programming time can be achieved by using a faster programming system. An AT91
Evaluation Board is capable of running a serial link at up to 500 Kbits/sec and can match the
fastest programming allowed by the Flash, for example, about 40 seconds per Mbyte when the
word programming becomes the bottleneck.
For more details about the Flash Memory Uploader protocol and the Host Loader Programming
System, see the application note page of the AT91 Products at www.atmel.com.
