V4 Firmware 1.5.1 build 66
3.1.1 New linux image
We have upgraded the linux kernel to version 3.2.43. This is to support 4 GB SD card. The start sequence for the new linux has been improved and we have added the possibility to activate a service mode before the SD card is mounted. During the startup of this new linux kernel we have added a tone signal to indicate a special position in the startup sequence.
3.1.2 Service mode during startup of Linux
We have added the possibility to activate a service mode before the SD card is mounted. This service mode is for service technicians that support the embosser. If you are an authorized service technician you can contact Index Support at email@example.com for a description of this new service mode.
3.1.2 Synthetic speech interface in Linux kernel
We have also added a synthetic speech interface to the Linux kernel and therefore the embosser can report error messages before the SD is mounted. This synthetic speech is in English and cannot be localized.
3.1.3 Automatic restore of the SD card
If the SD card is crashed and not possible to mount the embosser will start a sequence for restoring the SD card from Index web-site. It is also possible to startup the embosser without any SD card. In this case the embosser will wait until a SD card is mounted to the Embosser. The embosser will then start to restore the SD card from Index Braille website. IMPORTANT NOTICE is that a network connection with DHCP and internet connection is required for this function to work.
