New ContributorI am having issue with UART (RS-232 Serial Port) Intel FPGA IP v19.2.0 generation on Quartus pro 22.4.
The the RX path dose not receive any data. Generated code for the core seams wrong in module "dproc_qsys_uart_0_altera_avalon_uart_1920_tpslhhy_rx_stimulus_source" see attached generated code. Replacing UART Core IP with Uart LW IP solves the problem so I will rule out wrong connections on my part.
ContributorHi,
I will comeback to you soon
ContributorHi,
What device are you using now?
New ContributorAgilex
ContributorHi,
It seem i cant to reproduce the error.
may i know do you using GHRD or nit on your project and can you share the link?
Contributorhi any update?
New ContributorHere is a new test project that has noting but the qsys with uart IP. take a look at the RX signal and how it is been processed by the model.
ContributorHi,
After i open your design, I need to create my own top file right?, Because its does not here
ContributorHi,
I open your design and i saw error while opening the top file.
I would like to have a call with you to look more deeper
may i know when do you free?
what is your GMT, my GMT is +8.
New ContributorThe example project is there to allow you to generate IP source code. The only think you need to do is to generate qsys. Then you can analyze the source code that it generated.
ContributorHi,
Yes, we can generate the uart from qsys.
I would like to suggest to you, using the GHRD(https://github.com/altera-opensource/ghrd-socfpga
) then generate the uart instantiate IP, porting over to top level. im not sure if you doing that already for your project.
New ContributorIs generated code resembles the code that I have attached? If so can you take a look at the data RX path and in specific module "dproc_qsys_uart_0_altera_avalon_uart_1920_tpslhhy_rx_stimulus_source" and how we can remove "SIMULATION-ONLY CONTECTS" sections and replace it with the synthesis translation? I really do not want simulation only contents I need to simulate normal UART RX behavior!
ContributorHi,
Apologies for being late as im try to debug your case and attending other case.
We using GSRD and modify it. By using this method it should nearly accomplish the customer project.
The code generated maybe difference from what you provide.
