2 Memory organization

2.1 Serial Rescue Kit / Web Update

Two different procedures exist to upload the “Streaming Client” firmware into the

device:

The “Serial Rescue Kit” using the serial cable will upload the firmware files, the boot

loader and the “factory defaults configuration” which will erase the current

configuration. The “Web update” using a browser will upload the firmware files and

the “factory defaults configuration” but will not alter the current configuration. For

factory defaults and memory usage details see the following two sections.

2.2 Flash Memory usage

The “Streaming Client” firmware is using the built-in Flash memory as described in

the table below.

A page uses 64 kilobytes of flash memory. Flash memory of 2MB is assumed.

Please note: 0xC00000 is mirrored to 0xE00000 and 0xD00000 to 0xF00000.

Both update procedures (Web update & Serial Rescue Kit) respect the above

memory usage.

The above memory usage table must be used accordingly when loading single files

using advanced web update.

The target has to be in capital letters (i.e. WEB4).

The remote firmware update feature splits the FLASH into two partitions where one

contains the running firmware image and the other is reserved for the remote

upload and is normally empty. The partitions are automatically switched. The

complete firmware with all extension modules and resources must fit into 14 pages

(the fifteenth page is reserved for the bootloader).

The compound WEB update overwrites the whole FLASH with and stores the

Streaming Client firmware into the FLASH first partition (pages 0 to 14). If the
