9.6.1. Firmware Update

Firmware updates are performed through the MagnaWEB software, available for download on the Magna-Power Electronics website. MagnaWEB and firmware are released together, where newer versions of MagnaWEB will sometimes require upgrading the firmware. Firmware is forward upgrading only. Review previous MagnaWEB change logs before replacing firmware, since the older firmware can not be restored. Both forward and backward installation paths are supported for MagnaWEB software. When MagnaWEB establishes communications with the Accessory, it queries all board hardware revisions and firmware versions, to determine compatibility. If the Accessory is not compatible with the software, the option to downgrade the software or upgrade the firmware is provided, as shown in a pop-up dialog in Fig. 9.7. Before upgrading firmware make sure sources are disconnected and the Accessory is is in standby.
