is there some #arm cheatsheet for all #assembly instructions?

preferably for multiple ISA revisions (v7/v8) specifically.

#armv7 #amv8 #embedded

A tout hasard : quelqu'un à une idée de pourquoi en C++11

```C++
thread_local static QObject foo;
```

Ferait un segfault sur Armv7 mais pas sur x86_64 ?

QT5.15 ici. Pour le fluff, je rencontre ce cas dans qt5base/src/corelib/time/qtimezoneprivate_tz.cpp

dans QTzTimeZonePrivate::staticSystemTimeZoneId()

Is there someone that #crosscompile #linux #kernel with #rust for #armv7 or 32bit architecture?

Ich lerne gerade dass meine #Odroid #XU4 #SBC nur 32 Bit sind und #ARMv7 wird in #paperlessngx nicht mehr unterstützt. So habe ich erst mal die letzte Version 1.17.4 am laufen.

Das Ganze läuft auf einem dietpi.com Image im Docker mit Portainer.

anyone know a cheap server I can rent to compile #rust code on for #armv7? some reason I cannot feel like I can trust the cross-compilation on my usual x86 amd.

Anyone interested testing #RunCPM on #Android >=5.x (because of the Termux-App)
with #ARMv7 CPU?

Little roadblock on the way, I can't install a #poudriere jail of #FreeBSD 13.2-RELEASE #armv7 using ftp ... the required dist files just aren't there on the mirrors 😞

But hey, you can always build yourself from source 😎 so ... waiting again. I expect this to work as well, but we will see.

Awesome, this works 🥳

So, the #aarch64 VM running #FreeBSD I got for free from #Oracle now has yet another purpose besides testing #port builds: Build #armv7 packages! Might need them when I finally turn my #BananaPI into a thin client 😎

So, the GENERIC #kernel config for #FreeBSD on #aarch64 contains COMPAT_FREEBSD32.

Does that mean some #armv7 jail will just work there? Gonna give it a try, would be great for building armv7 packages 🤔

With #AlmaLinux I can now employ another family of linux distros to compile my sources.
I haven't heard about #Redhat since Y2K, when I ran too often into broken packages and scripts, so I grew up with #Debian and #SUSE derivates.

The Redhat compatible Alma works out of the box and `dnf` installs all without problems. I just needed to enable one additional repo for some libs.

The only thing I miss is an #ARMv7 #docker image for my good old #Raspberry Pi ... but that's just for fun.

@Toasterson @josephholsten @marcan @lina @AsahiLinux @Raspberry_Pi @geerlingguy O.O

But it's not an actual UEFI, so you may not assume regular #aarch64 / #ARMv7 + #UEFI imeges will just run, as the #UEFI also initializes [not only PCIe] devices and provides the OS with basic access and device descriptors (just like #BIOS did).

Whereas the SoC is stupid or rather mute and requires the OS to know it.

@josephholsten @Toasterson @marcan @lina @AsahiLinux @Raspberry_Pi beyond that the #Pi4 / #CM4 / Pi400 is just an #ARMv7 #aarch64 machine.

Fortunately there is extensive #documentation on the #RasberryPi [unlike basically all #clones like the #BananaPi] so #porting it works fine...

And as people like @geerlingguy can attest, their custom #Linux #Kernel howto should be accurate to get started:

I've done a benchmark between Rust, C, Common Lisp and Python on my SBC which has ARM processor and here are the results:

#FreeBSD supports #ARMv7 so well that this old #RaspberryPi 2 got a dedicated case today

Ich könnte Schwarmwissen gebrauchen. Kennt sich hier jemand mit #hardwarehacking aus? habe eine #heimvision #hm311 #cam. Seriell #uart Verbindung steht. Hab sowas noch nie gemacht. #SigmaStar #ssc325 #armv7 #uboot201501 #kernel 4.9.84 #buildroot 2017.08-g239d7d0 ist drin. Würde die #firmware gerne #dumpen und ein #backup zu erstellen, bevor ich weiter damit rum spiele.

#x86_64 and #i686 builds are provided, it is technically possible to compile for #aarch64 but I couldn't get the resulting binary to work on my device. It's a #Windows #EXE that runs fine in #Wine on #Linux (where I do my coding). #armv7 builds seem to be blocked on what might be a bug in a third party library.

I am unreasonably excited about a new #openbsd #armv7 snapshot being released.

that means I can spend another 6 weeks poking and prodding at the build, hoping it actually works this time.
