Software Image Management
The SR1 software contains two software components.
Boot loader: Small and robust code that starts after power up or reset and launch the
application. For more information about Boot Loader update see paragraph 11.3 below
Application: Stored in the Flash memory and is field upgradeable.
At boot time the SR1 boot loader verifies whether a new software image was selected as active
and performs the following:
If a new image is selected, the boot loader copies the image from the on board flash memory,
to the CPU flash memory.
If no new image was selected, the boot loader uses the image already stored in the CPU flash
memory.
If a new image fails to run properly on the CPU, the boot loader automatically replaces it with a
previous running image.
11.2.1 Software Image Upgrade using TFTP
Note:
Before performing the procedure described below, please contact support@ayecka.com.
Note:
Before upgrading software – make sure to write down all configuration of the device
Before performing the procedure described below,
A software image upload by TFTP is very similar to the process of uploading an FPGA file
using TFTP. Refer to paragraph 0 for further details:
After uploading a new software image using TFTP it is required to be activated in order to be
loaded after the next Reboot or power cycle.
When the SR1 reboots and detects a new image on the Flash memory, it copies it to the CPU
internal Flash memory (indicating the copy of each sector with a dot on the display):
