Package: 324-FBGA (19x19)

Obtain firmware source code

Source code of firmware distributed under GPLv3 license and available on github:

git clone https://github.com/aospan/NetUP_Dual_Universal_CI-fpga

Firmware compilation

  • Install Altera Quartus II Web Edition (free). Current version 14.1
  • Open project (File->Open Project) Dual_Universal_CI.qpf
  • Run "Processing -> Start Compilation". Compilation will take about 6 minutes on fast CPU
  • Resulting firmware placed into out/netup_unidvb_top.sof file

Firmware preparation to upload into NetUP Universal Dual DVB-CI card

netup_unidvb_top.sof file should be converted to netup_unidvb_top.bin. Below commands tested on Ubuntu Linux 14.10 with Altera Quartus II installed into /mnt/sdb/altera/14.1 and openjdk-8-jre package installed

  • setup environment
$ /mnt/sdb/altera/14.1/nios2eds/nios2_command_shell.sh
------------------------------------------------
Altera Nios2 Command Shell [GCC 4]

Version 14.1, Build 186

  • conversion to srec
$ java -Xmx512m -jar /mnt/sdb/altera/14.1/nios2eds/bin/sof2flash.jar --input=netup_unidvb_top.sof --output=netup_unidvb_top.srec --compress --epcs --offset=0

Upload firmware (netup_unidvb_top.bin) to NetUP Universal Dual DVB-CI card

  • load m25p80 if not already loaded
$ modprobe m25p80
  • reload netup_unidvb.ko with spi_enable=1
$ rmmod netup_unidvb.ko && modprobe netup_unidvb.ko spi_enable=1)
  • check mtd file for proper mtd device number
$ cat /proc/mtd
dev:    size   erasesize  name
mtd0: 01000000 00040000 "fpga_04:00.0"
  • write firmware to flash
$ flashcp -v netup_unidvb_top.bin /dev/mtd0
Erasing blocks: 2/2 (100%)
Writing data: 387k/0k (100%)
Verifying data: 387k/0k (100%)

DONE

Remember to POWER OFF card (reset not enough) to new firmware take effect !

FPGA Simulation

Simulation files available in folder testbench. Some parts of firmware can be simulated (without real hardware).

  • start modelsim
$ /mnt/sdb/altera/14.1/modelsim_ase/bin/vsim
  • Open (File->Open) dvb_unici.mpf
  • In "Library" remove "work" and create it again (workaround for problem in modelsim)
  • Run "Compile->Compile All"
  • Choose Project (for example, "ci_control_tb") and run "Execute"
  • Do simulation with "Simulate -> Run"
