Firmware update using SD memory card

To perform a firmware update using a SD memory card, follow the steps:

1. Copy the firmware image on a SD memory card. The name of the firmware typically looks like “v3-9.bin”. You find the latest version later on this site. Usually, the downloaded firmware is zipped – use your preferred unzip program.
2. Create a file “autorun.txt” on the same SD card. This file contains commands to be executed after power up. Fill this file with the following commands:
   
         loadfw v3-9.bin
         progfw
3. Switch power off the Avisaro module. Insert the SD card.
4. Switch on the Avisaro module. The process will be started by first loading the firmware into the module (loadfw) and than performing the firmware update (progfw). The process can be supervised by observing the LEDs on the base module. A flashing red LED signals a ongoing process. A solid red and green LED signals finished process.
5. Switch off the module, take out SD Card. Remove the files to avoid an accidental firmware update.
6. Alternatively to using the autorun.txt file, the commands can be entered directly using the command line interface.
