Armvh6 LibDRC Illegal Instructions (Core Dump)

[Marco Grießbach]

Hi guys thank you for this nice Library ;)

Currently iam running Libdrc on armhv6 device with Archlinuxarm.

The Gamepad is connected to the WLAN-Stick and runs smoothly (hostapd, netbook). The LibDRC contains some Demos but all of them won't start -> Illegal Instruction (Core Dump). I've write my own small SDL Application. It runs until i initialize the Streamer. What's the problem? Compiled all Libs without any errors!

Can anybody help?

Ok, i dont see what your problem, Illegal Instruction? what does that mean, does the gamepad not accept your pc? oh and this off topic, but how did you install the kernal (sorry for asking you on an error but if i can get it installed, i could proberly help you, also can you go more indeapth about what the error is)

On Archlinux Arm you need the latest Kernel --> Pacman -S linux-kernel-3.13-1-rpi linux-headers-3.13-1-rpi.

That's all (activate your Kernel in config.txt). You need also the latest source for the arch linux kernel and rewrite mac80211 (iface.o) -> see official source and you are good to go.

The Gamepad is connected to my PC and the Handshake is succesfully. If i run 3dtest or tsdraw the app starts and hangs on demo::init (at line g_streamer = new drc::Streamer(); ) if i run it at terminal i became the error "Illegal Instruction (Core Dumped) at the Position. Is this a problem with codec drc-x264 or with LibDRC self?

Thanks for reply!

Okay problem solved :)

In your configurationfile for the drc-x264 is the Cortex-A8-Processor standard. That's an Armv7 Device and not an ArmV6. I started configure again with --disable-asm. Compiles and runs flawlessly.. but very,very slow..
