11 SR1 Software and Firmware Upgrade
The SR1 internal Flash (non volatile) memory stores 2 images of software, 2 images of
firmware and an image of the Boot Loader.
The images can be managed to provide field upgrade of the SR1.
For each type of image (Software or FPGA) there is an active image and non active. The active
image is the one to be used in next cold reboot or power cycle.
Images are uploaded using TFTP protocol. When loading a new image it is replacing the non
active image.
Specific hardware versions of the SR1 support only Firmeware version management.
Note:
The SW release upgrade may delete the current configuration. Please make sure you retrieve
and save configurations form the SR1 prior to upgrade
When upgrading to new Bootloader the recommended order is as follows:
• Upgrade the application and reboot the SR1 with the new Application
• Upload new BootLoader, Activate it and reboot with new Boot loader
• Upload FPGA file and Application
Telnet and TFTP share same resources, it is recommanded that during the TFTP seassion,
Telnet will be disconnected.

FPGA Image Management
At boot, either after a power cycle or cold reset, the SR1 loads the firmware image to the
FPGA. This process takes less than 5 seconds. The SR1 stores two images of the Firmware,
where one is set to be active and used to configure the FPGA at the boot or restart. The file
type for Firmware upgrade using TFTP is XXX.afp
Note:
The functionality of the SR1 is not interrupted during the FPGA image TFTP process
To load a new image using the Trivial File Transfer Protocol (TFTP):
Select the FPGA upgrade menu from the system menu.
Define the following:
IP address of the TFTP server
Filename of the image to load,
Select 0 to save the parameters to the NV RAM.
From the FPGA upgrade menu select the Start the upload procedure option to begin the
download process.
The example below shows the setting of FPGA image download menu:
