  1. Checkout whether your module is enabled in the petalinux rootfs config menu
  2. Make sure that you've properly modified the Makefile of the module

If everything goes well, the output file will locate at ./build/tmp/sysroots-components/plnx_zynq7/axidma/lib/modules/4.19.0-xilinx-v2019.2/extra/axidma.ko after compilation. Here I'm using petalinux 2019.2, the path may differ as you may have a different version of petalinux.
