FPGA loader

On this page, you will find all the informations needed to use the Linux FPGA loader driver. This driver allows you to load the FPGA of your APF board from Linux userspace/shell (ie FPGA reprogrammation after Linux boot).

Driver installation

Driver is installed in default Armadeus rootfs.

For the hackers, code is located in target/linux/modules/fpga/dev_tools/fpga_devtools/.

Driver usage

 # modprobe fpgaloader
 fpgaloader v0.9 loaded

• The FPGA loader driver is usable through the standard Linux filesystem interface. To read the available configuration, do:

 # cat /proc/driver/fpga/loader
 spartan slave serial

• To upload a new firmware (here bramtest_top_apf.bin), use:

 # dd if=bramtest_top_apf.bin of=/dev/fpgaloader
