Re: First kernel compilation: undefined instruction: 0[#1]PR

Sorry for the late reply. My kernel is still working properly (I haven't recompiled any updated kernel versions though) and my Raspberry Pi is happily working as our local printer server. As requested I'll share the compiled kernel. I think I managed to get all the correct files together, but if som...

Re: First kernel compilation: undefined instruction: 0[#1]PR

Problem solved. I managed to compile the 3.6.11+ kernel and it works perfectly fine.

@Licaon_Kter: I need the module that adds USB printing (usblp) it is not included in the normal kernel. then add an issue here: https://github.com/raspberrypi/linux/issues?direction=desc&sort=updated&state=open I think this is not an issue. This is a choice, since usblp is a module that very few pe...

Re: Kernel 3.2.27 panic !

Hey guys, I tried to first compile the 3.2.27 kernel with gcc on ubuntu with the usb printer driver embedded into the kernel. This led to produce the same kernel panic in mm/slab.c (2878). then again I recompiled the kernel with building usb printer driver as module and the kernel booted successful...

Re: First kernel compilation: undefined instruction: 0[#1]PR

The ARM kernel uses undefined instructions to implement BUG/BUG_ON(). This leads to problems where people don't read one line above the Oops message and see the "kernel BUG at ..." message and so they wrongly assume the kernel has hit an undefined instruction. So the bug is not the Undefined Instru...

@efflandt: Prior to compilation I had updated my Raspbian to the latest version available, and used the config file that was supplied with it.

Re: Wake from halt

I'm confused. I thought that to reboot the Pi, I'd simply create NC switch on the power supply. Pushing it would cycle the power and reboot the pi. What is the added value of this new method?

First kernel compilation: undefined instruction: 0[#1]PREEMT

EDIT: I've no idea whether power users is the right place to ask this. I'm definitely not a power user, but various threads urge us to keep the 'scary' things like kernel compilation away from the first time linux users. The troubleshooting forum seems to be for actual problems with the Pi. Mine run...

Re: FATAL: Module usblp not found.??

Thanks for all the help. A note to future readers: The previous post mentions the command make menuconfig However when cross-compiling for Rpi one should take care to use: make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- menuconfig instead, otherwise the build will fail.

Re: FATAL: Module usblp not found.??

Ah, thanks a lot. I had no idea something like 'make menuconfig' existed. I was going to manually edit the .config file.
Should I enable 'parallel port support'? Or is that reserved for 'real' parallel ports?

Re: FATAL: Module usblp not found.??

I followed these instructions up to: cp arch/arm/configs/bcmrpi_cutdown_defconfig .config but I can't find the right configuration option. I searched for USB_PRINT, USB and PRINT but I can't find the USB _PRINT option. Can I add it to the config file? If so, what's the exact name I should add? Thank...

Re: Use Pi to switch on/off Wii remote buttons

A friend of mine recently did something similar. He automated a remote. To switch the buttons he simply soldered a transistor (emitter ground oriented) across the button pins. These were physical push buttons with pins, so it was very easy. I imagine the Wii only has a contact surface on the PCB, wh...
