Software Start-Up
When the radio is turned on, the following processes are carried out on the
main board:
Note This process describes the normal software start-up into normal
radio operation mode.
1. The FPGA image, which includes the RISC processor and the cus-
tom logic, is loaded from the serial flash to the FPGA.
2. The RISC processor executes the boot code, which carries out an
initialization and auto-calibration, and—in case of a fault—generates
an error code for display on the control head.
3. Normal radio operation starts with:
■ the RISC processor executing the radio application code,
including application software for the analog and/or digital modes
■ the DSP executing the DSP code for processing of digital signals
in analog and digital mode
■ the custom logic executing additional digital signal processing
