7.1 Programming from the Bootloader
Upon each reboot of the InSpec you will see the following text.
InSpec bootloader version 2.04
Press the space key to abort application booting
The ‘press the space key’ prompt offers the ability to interrupt the boot sequence to access the
bootloader command shell. You may wish to do this to review and manage the contents of the SD flash card prior
to application load or to reprogram the application manually from the bootloader command with a file on the SD
card. After pressing the space key, you should see the following bootloader command prompt:
Note: If the SD card is not present a warning will appear prior to application start as follows:
The application will then attempt to start. The following conveys this:
At this point, if the application flash bank is programmed then the application will start, and you will see
the usual command prompt as follows:
Enter password to access shell:
In the event that the application flash bank is not programmed, or a fault exists, the bootloader
application will cyclically reboot until the sequence is either interrupted by pressing the space key or an SD card
is inserted containing a valid application image called ‘FLASH_APP.ONE’.
7.1.1 Automatic Software Update via the bootloader.
To automatically update the version of your application, you simply have to rename the latest
binary release file, e.g., rename SAMPLER_XX.BIN to FLASH_APP.ONE Now simply reboot the
machine. Upon reboot the bootloader will detect this file as follows:
InSpec bootloader version 2.04
Press the space key to abort application booting
