Modifying the contents of the RAMdisk

The contents of the RAMDisk for the ARM Linux (uramdisk.image.gz) can be extracted to a local directory for you to modify:

make ramdisk-open

The RAMDisk is extracted to ramdisk/ in fpga-zynq/zedboard. Note that the default user in the ARM Linux is root, so use sudo when revising the files.

You can repack the RAMDisk using:

make ramdisk-close

The extracted RAMDisk remains at ramdisk/. It can be removed with:

sudo rm -fr ramdisk
