very basics: how to use UART1 in zybo zynq-7000? in FPGA Posted January 10 16 minutes ago, jpeyron said: Hi @Avinash, Welcome to the forums! I have not used Microblaze in a Zynq design as of yet. Here is a non-digilent tutorial Hello World on Microblaze UART on PS in Zynq Processor that discussed doing this that should be helpful. thank you, Jon Thank you. This seems like a solution that could work. I am actually trying to get FreeRTOS on Microblaze in Zynq FPGA. Do you also have any references for me to achieve this.
