CB-CV-SOM FPGA default project

Synopsys

Simple almost blank FPGA project for CV-CE-SOM (aka BlueSoM) board.

Description

This project makes avaible to turn CB-CV-SOM board orange LED on blinking with given period. Duty cycle = 50%

The register to control period:

• CPU address : 0xC000_1000
• 32-bit register, but only lower 16 bit are accessible; writing at higher 16 bit has no effect.
• Period unit is milisecond
• Minimum value 0x20 (protected)

All memory mapped items in FPGA (Base bus address/end bus address):

• System ID Peripheral (the ID is 0x01000001) (0xC000_0000/0xC000_0007)
• Avalon-MM interface (named fpga_regs) (0xC000_1000/0xC000_13ff)
• On-Chip-Memory (4KB) (0xC000_2000/0xC000_2fff)

Learn more about this system via qsys.

If orange LED doesn't work, make sure you use the appropriate preloader binary.

Build

Use Altera Quartus-14.1 (build on other versions not tested) Launch it, open top.qpf and push "start compilation".

Your .sof, .rbf will be ready in output_files/

Build preloader:

• This stage shall be done only after fpga firmware building complete
• cd hps_isw_handoff
• <your quartus path>/embedded/embedded_command_shell.sh
• bsp-create-settings --type spl --bsp-dir build --preloader-settings-dir soc_hps_0 --settings build/settings.bsp
• make -C build
