I tried to use petalinux2021.2 to build “BOOT.bin, boot.scr, image.ub” for my Pynq-Z2 board, and I used .xsa built by Vivado 2021.2. My Vivado project is inherited from a project of Vivado 2019.1, which runs well with pynq v2.7 image.
My question is that my uart port can’t print nothing on Putty after I switch on my Pynq-Z2.
My Baute rate is 115200, and inside my petalinux project and my Vivado project, I opened only uart0, and I used it in “Serial Settings”.
