XUartPs compatible FT230X devices

Jump to solution

Hi,

 

I'm trying to bringing up a custom board with a FT230X USB-Serial Converter. I'm testing the board with the xUartPS_Hello_Word Example from Xilinx SDK, but i only receive garbage on the Serial Port Term of my PC, like when the baudrate is wrong. I'm using the XUartPS Standalone Driver, but i certainly don't know if it is compatible with FT230X devices. I have only fount FT230X drivers over operative system, so i don't know other way to implement it on a standalone driver if it is not compatible. Any idea?

 

Thank you in advance

Ok i have solve it, it was a reference frequency problem. Thankss for the help!

Hi @eduardoparra,

 

Did you with different baud rates?

 

Thanks & Regards,

No, i used the default Baud rate : 115200. I have opened the serial port console with all baud rates posible and i only keep unreadable characters.

@eduardoparra Can you get an oscilloscope onto the signal and check the data and the speed? The obvious risk with an FPGA is that the clock configuration is wrong, so that the baud rate is not any of the standard options. An oscilloscope can tell you the true speed instantly, as well as identifying issues like incorrect polarity, incorrect byte length, parity, etc.

The frequency of the signal is 100.000, when my configuration is 115200BaudRate, which i think is not very accurate.

What did you set the reference frequency to?
