I swear if I need to `petalinux-build -c rootfs` one more time…

How’s your Friday going?

Very useful guide by #WhitneyKnitter on @hackster_io

👉 https://www.hackster.io/news/an-fpga-take-on-the-raspberry-pi-petalinux-on-the-zynqberry-67dd421d25aa

A few updates though:

• Apparently, you don’t export an hdf-file anymore, it’s an .xsa file; so for --get-hw-description simply use the directory into which Vivado spat your .xsa file upon hardware export.
• A couple of petalinux config options have changed. E.g. you can now select an ext4 fs explicitly.

Oh, and a general hint: upon installing #petalinux, the docs state, that --dir sets the installation directory. Yeah, but only if said directory exists. Otherwise it’s silently ignored and installation goes to current working directory. Because, duh, I guess -.-

As the occasional #petalinux -user (which sits on top of yocto if I see this correctly) I’m happy to hear about the funding!

It's amazing how much of Computer Science is actually about learning yet another package management system.

For me (in that order): #FreeBSD ports, libtool user-land madness, #Debian packages, and now #Petalinux recipes.

Never getting boring...

The #XKCD comic "Compiling ⚔" was probably inspired by development with #petalinux.

Any #uboot (the #bootloader) experts here? I’m trying to boot a #PetaLinux image, but I get

Verifying Hash Integrity ... sha256 error!
Bad hash value for 'hash-1' hash node in 'ramdisk-1' image node
Bad Data Hash
Ramdisk image is corrupt or invalid
Booting using Fit image failed

even though when I extract the image (no matter whether with dd or dumpimage), the resulting SHA256 _does_ match the checksum listed in the #FIT. What’s going on?
