Linux Hellow World!

Intrermission: sdk(necessary files for Vitis)

In order for Vitis’ application to compile, the necessary libraries need to be installed. This can be done from Petalinux:

$ petalinux-build --sdk
$ petalinux-package --sysroot --dir /path/to/empty/destination/sysroot
^ (this will populate sysroot with /lib).

Platform

Create a new platform with “linux” as the operating system.
(Alternatively, expand an old platform with a “new domain”).
Also: No need for “boot artifacts”:

Link the petalinux .bif file, located either at petalinux’s: my_project/images/linux directory (FIXME: After config?) or the tftp/dest (if a tftpserver was used).
Link the “pre-built image directory” (either my_project/images/linux or tftp/dest).
Build [the platform].

FIXME: Prebuilt fsbl ?: No

Application

Create a new application from templates(Linux Hellow World) (under File/New Component/From Examples).
Set the sysroot directory (previously generated through petalinux(--sdk)) to the (inner) sysroot/sysroots/*-gnueabi folder:
Build [the application].
- Note the generated .elf file[!].

Take Five 🎹🎷🎷🎶

From this point on, the hellow_world.elf file can be [copied to, and] run from any partition on the SD card.

(As usual, copy BOOT.bin, boot.scr and image.ub to FAT32 partition, extract rootfs.tar.gz to ext4, and copy, for example onto ext4, the hellow_world.elf).
(The latter can be run like $ ./hellow_world.elf😎).

Troubleshooting

[Newly created [Linux]] Domain [at previous [standalone] platform] [is] not visible: Restarting [Vitis] might work.
