Linux Kernel Modul for Loading Designs into Altera FPGAs

Linux Kernel Modul for Loading Designs into Altera FPGAs

Use the dd command to load RBF files:

# dd if=design.rbf of=/dev/fpga_loader bs=5M

The current module supports the Colibri modul from Toradex (iMX6 processor). The loader uses the GPIO subsystem. For other platforms you simply have to adjust the GPIO pins numbers.

Building

Choose the target plattform and find its appropriate kernel configuration together with the kernel headers.

• arch: target plattform such as powerpc or arm
• comp: cross compiler such as powerpc-linux-gnu- or arm-linux-gnueabi-
• path: path to kernel headers (path to root of kernel repository)

Example for ARM

user@hostn:~/myproj/fpga_loader$  export ARCH=arm
user@hostn:~/myproj/fpga_loader$  export CROSS_COMPILE=arm-linux-gnueabihf-
user@hostn:~/myproj/fpga_loader$  make KERNELDIR=~/kernels/linux-toradex

Using a compiler which is not installed on the system, the corresponding path must be added to the environment variable:

user@hostn:~/myproj/fpga_loader$ export PATH=~/compilers/gcc-linaro/bin/:$PATH 
user@hostn:~/myproj/fpga_loader$  export ARCH=arm
user@hostn:~/myproj/fpga_loader$  export CROSS_COMPILE=arm-linux-gnueabihf-
user@hostn:~/myproj/fpga_loader$  make KERNELDIR=~/kernels/linux-toradex
