Gibberish being displayed on the Serial Port

I'm kind of new to SDK development and working on the PS side. I have 3 designs for a certain Image processing application - one for DMA, one for HDMI interfacing and the final one combining these two.

The problem I am facing is that on rerunning the same code on SDK, sometimes i get legible text (that i have output using xil_printf() ), and sometimes I get just random rubbish symbols. My serial port is configured at a baud rate of 115200, and while the first two designs work even when this gibberish is displayed, the third does not.

What could be the reason I get random symbols on the serial port rather than legible data, especially when it works half the time for some designs and doesn't work at all for others?

Is this a custom board, or a development board. What clock are you providing to the UART?
