I have been using the arty z7 and kria som’s… i want to make use of these other alchitry boards i own, but i need to find a way to use the alchitry serial connections. is there some way already known for how to use the usb connection in the fpga fabric with vivado? some module i can copy from the alchitry bitstream? ok, im commencing the inquest to find the module from github… give some step by steps please… i dont want to reinvent the wheel. i am considering a method to implement a dfx mode for my os on non-zynq pl’s fpga’s. im doing the microblaze mcu instead of zynq. ptv2 is good for this, lots of room. there must be a better way (usb connection) than using tx and rx to my other au board as the ‘serial’ interface.
oops, should have looked in the project tree and found the vivado project and I see the rx and tx modules. looks complex to read, but i can just re/set the baud and clock freq params … that will be ok if thats all? thanks for your patience on my slow learning curve.
ok, i only have questions regarding the way the schematics show 8 bits for usb data on the pt board? but only use the d0 and d1 for now? what way is possible for the onboard serial bus here to use all 8 bits and we make a new pt v2 tx and rx modules into the base project list?
See Serial Interface for a tutorial on using the serial port.
The Pt has a lot more connections to the FT2232 than are needed for the default serial interface. This allows you to use the FT2232’s FIFO interface which is faster but requires other work (custom PC side software).
