DSP Firmware Upgrade:
The DSP program file extension is “.out” and it is stored in the Flash memory of the M2TE and
activated in the DSP at the system start-up.
To update the DSP firmware, the user needs to enter the file name (under File Name text box) of the
DSP program file (*.out) and the Program Number to load it into, and if the file contains a Boot
Loader it can optionally be programmed into Flash by checking the box. When done, press the
Upload File and Program Flash button to begin.
The Boot Loader boots from Program 2 if it is present, otherwise it will boot from Program 1.
Program 1 is designated as the Factory program and should never be upgraded in the field. Program
2 is designated as the Field Upgrade program and should be used for all field upgrades. Should the
field upgrade process ever fail, the Boot Loader will revert to loading the factory program ensuring
that a good image is always available to load and run. Rarely, if ever, should a Field Upgrade require
updating the Boot Loader and this choice should not be selected unless specifically instructed to do
so.
Note: If upgrading new DSP firmware ensure to load the corresponding Xilinx firmware (if there is
one to be upgraded) as discussed in the next section before re-powering the transmitter.
Xilinx Firmware Upgrade:
The Xilinx program file extension is “.bit” and it is stored in the Flash memory of the M2TE and
activated at the system start-up.
