This command performs the file transfer to the GPS Receiver. You will see a file transfer progress
message while it is performing the transfer. Next, issue the following command to the Meridian II
console to reset the GPS Subsystem (and Receiver):
subsysreset
After it completes, wait about 60 seconds and issue this command to check the GPS Receiver ver-
sion:
rcvrversion
You should see a message like this:
F/W 6010-0081-000 Ver 1.04 - FPGA 6020-0014-000 Ver 01 - JAN 28 13:08:52 2013
The firmware version should match that of the binary file that you uploaded.
Problems with the GPS Receiver Upgrade
Should you have difficulties with the upgrade due to a corrupt file, power failure during upload, or
other accident, do not be alarmed. Even though you may have lost the existing application program,
the GPS Receiver bootloader program will remain intact. Correct any problem with the binary file
and retry the upload procedure. If you are still unable to successfully perform the GPS Receiver
upgrade, you should contact Customer Support at EndRun Technologies.
Performing the GPS Receiver FPGA Upgrade
This section has instructions for upgrading the Field-Programmable Gate Array (FPGA) resident
on the GPS Receiver. This is rarely, if ever, used so is not an option on the HTTPS interface. If
you want to upgrade the GPS Receiver, see the section above called
Performing the GPS Receiver
Upgrade
.
First you need to download the FPGA image from the EndRun website to a place on your network
which is accessible to the Meridian II. The link to the Meridian II upgrade page is shown above.
You may transfer the file to your Meridian II using either
ftp
or
scp
. If you are using
ftp
to per-
form the upgrade, transfer the previously downloaded file using
binary
transfer mode from the remote
host to this specific file on your Meridian II:
/tmp/rcvrfpga.rbf
. The FPGA image will be named with
the image part number and version like:
6020-0014-000_02.rbf
. When following the instructions be-
low, substitute the name of the actual FPGA image that you are installing for
6020-0014-000_02.rbf
.
You will be transferring the file to a temporary file,
/tmp/rcvrfpga.rbf
on your Meridian II.
ftp remote_host
{
perform ftp login on remote host
}
bin
{set transfer mode to binary}
get 6020-0014-000_02.rbf /tmp/rcvrfpga.rbf
{transfer the file}
quit
{
close the ftp session after the transfer
}
If you are using SSH to perform the GPS Receiver upgrade, you may open another command window
on the remote computer and securely transfer the FPGA image to
/tmp/fpga.bin
using
scp
from the
remote computer. A command like this could be used:
