flink on Phytec PCM032 Board (mpc5200)
flink was tested with the FPGA on the mpc5200io module as well as with an external FPGA connected through a SPI interface.
Onboard FPGA connected through Local Plus Bus
The following example describes in detail how a Phytec PCM032 Board containing a mpc5200 and a FPGA is configured to be used with flink. The FPGA will contain a single channel PWM module and a single channel GPIO modul.
Setup
- Configure the board with a working Linux kernel and root file system or use the system described in Installation von Emdebian Grip auf den Phytec phyCORE-MPC5200B
- Make sure that the device tree blob is up-to-date. It must contain a node for the FPGA sitting on the local plus bus.
- Get necessary sources for the flink project.

Configure the FPGA
Proceed as described in VHDL.
- In 5: add a block gpio and a block pwm to the system. Also add a lpb_mpc5200b_to_avalon module. Leave the standard values as they are except for the PWM module, whose base clock should be 33000000.Invalid LinkAdding an interface block
- After 9: the System should now look like:Invalid LinkComplete system
- In 14: choose the pins as follows:
