Different files will be loaded onto each partition that you created on your SD card. Be careful that files are being loaded on the correct partition.
In a terminal navigate to the folder we cloned from github 'OcPoC_Zynq_Mini_Files' and execute the following command.
cp uImage devicetree.dtb uramdisk.image.gz BOOT.bin /media/<username>/boot/
In a terminal navigate to the folder you cloned 'OcPoC_Mini_Zynq_Files' and execute the following commands.
cd PX4_rootfs sudo cp ubuntu-rootfs1.tar.gz ubuntu-rootfs2.tar.gz /media/<your_username>/rootFs/
cd /media/<your_username>/rootFs sudo tar xvf ubuntu-rootfs1.tar.gz sudo tar xvf ubuntu-rootfs2.tar.gz
sudo rm ubuntu-rootfs1.tar.gz sudo rm ubuntu-rootfs2.tar.gz
Navigate back to the PX4 Firmware directory (the top directory of the PX4 code). The first time you run PX4 on OcPoC, you'll need to copy a few folders in addition to the PX4 executable. These directories are already included in the root file system copied from OcPoC_Mini_Zynq_Files, but it's a good idea to copy the directories from your working PX4 directory. Execute the following commands:
sudo cp -r ROMFS/ /media/<your_username>/rootFs/root/. sudo cp -r posix-configs/ /media/<your_username>/rootFs/root/. sudo cp -r test_data/ /media/<your_username>/rootFs/root/. cd build/posix_ocpoc_cross/ sudo cp px4 /media/<your_username>/rootFs/root/.
NOTE: after you have the ROMFS, posix-configs, and test_data folders located on the SD Card, you only need to copy a new PX4 executable to the SD Card when you build a new PX4
