TMS320F28P650DK: FSI HW control

Part Number: TMS320F28P650DK
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi TI Team,

I can't find the CLB configuration file for FSI HW control method mentioned in FSI multi-node application nodes. My case is to connect multiple nodes via FSI and have the least amount of delay and overhead on the CPU. so want the CLB to forward the frames to the next node if the frame type is PING or USER frame with no match on the tag.

Regards,

Reza

    Hi Reza,

    Do you mean the following CLB config files? They are generated by sysconfig when you build the _node project.

    Let me know if you are still missing any files.

    Regards,

    Yes I checked those, as far as I can see, they configure the CLB to sync FSI with a PWM, I can't find the one that does the HW control. I need the config file which referred to in the application node which does the HW control and bus arbitration. so using CLB for FSI, requires the CLB logic to decide when to short the TX and RX to just forward the frame and when disconnect that since the node itself has something to send.

    Discussion taken off forum. Adding high-level details for future reference:

    In F28P65x device we do not have the option for CLB to control SEL_TDM_PATH. It instead can be controlled by FSI RX TRIGGER. TRIG_WIDTH0 should be configured based on max pkt size configuration for the specific use case.

    Best,
