Why data loss may happen during PC to ZedBoard UART Communication?

#UARTDataLoss #Zedboard #USBtoUARTBridge
In this video we discuss why data loss may happen when we transfer large amount of data between the PC and the ZedBoard through the UART interface although we configure correct Baudrate.

Good video
How can we increase the buad rate of transmission from 115kbps to 921600 bps or similar? Can this be done at SDK end and at TeraTerm end so that data can be transmitted at much higher rates.
Thanks

The maximum baudrate supported by PS UART is 921600. Easy way to set is to configure it in the block design. Double click PS under PS-PL configuration, you can modify it for UART1. Through software also you can modify it but will have to use XUartPs_SetBaudRate() function available in the xuartps.h header file. It is discussed in the subsequent videos. Teraterm yes you can just set the same baudrate configured for the board.

But you didn't insert delay when transmitting data from PC to Zynq and the data is correctly transmitted. So, does it mean the bridge takes no time to convert from USB to UART?

I think that's where the XUartPs_Recv comes in I think it handles that delay
