Hi, dear elites,
In ZYNQ, it can enable UART-0 and UART-1 on the PS side. While we install the v2.4 image on PYNQ-Z1 or Z2 FPGA, how can user check if the version of image already include UART-0 and UART-1 in the device tree?
Thank you

Thank you
First install device-tree-compiler
on your board:
sudo apt-get install deivce-tree-compiler
Then run
dtc -I fs /sys/firmware/devicetree/base > mydt.dts
Check mydt.dts
to find out if you have UARTs in your device tree.
Hi, Rock,
Thank you for the information.
It works. After check, I can see both uart-0 and uart-1 in the dts log of pynq v2.4.
If that’s the case, does it mean the device driver of UART is already installed in the pynq v2.4 under Ubuntu18.04 ?
Thank you
