If you don't want to mess with the ZYNQ you can always use a 3V TTL USB UART cable or breakout board from Adafruit or Sparkfun connected to PMOD pins. They are cheap and worth having around.

Actually we are using TTL USB UART cable, the uartlite txd and rxd pin are connected to Y11 and AA11

Make sure stdin and stdout are set to your axi uartlite ip in the BSP settings of your hardware platform.

Yes i verified and stdin and stdout are set to  axi uartlite ip in the BSP settings of  hardware platform.

We are trying to test our I2C IP (microblaze image) on zedboard, for debugging purpose we want to enable the printf fuctionality so we integrated Xilinx Uartlite in microblaze design but when we run the sdk software code the content of printf is not getting printed, it is printing some vague characters(WE tried to print "Hello World" via sdk code). The baud rate of UArtlite is set to 9600. We verified if signal is coming on UARTLITE txd pin using ILA . The clock and reset coming to the microblaze design is coming from the  RCC in the CPUSS. The board clock is coming to RCC , the I2C and UARTLITE signals are ported on the board pins . Can anyone help me resolving the issue  ?
