Does petalinux compile the .hdf file into bitstream file itself?

Jump to solution

I used "petalinux-config --get-hw-description <path_to_hdf>" to initialize the new PetaLinux project, and there is only one file named "Z7020_LINUX.hdf" in the folder <path_to_hdf>.

After the importing, I found in the folder "./project-spec/hw-description/", there is a Z7020_linux.bit file which is identical to the one generated in Vivado, along with some ps7_xxx.c and .h files to make a fsbl, but I didn't put them under the <path_to_hdf> folder. Does this mean petalinux compiled the bitstream file Z7020_linux.bit itself?

Thanks.

when you use petalinux-config --get-hw-description to import HDF, it will copy HW design into your petalinux project <proj-root>/project-spec/hw-description/
HDF is just a zip file which contains HW information, bitstream, ps7_init*, etc.
