Crui 3.12 on ARM 11 (Raspberry Pi model 1)

I have been trying to get Criu running on ARM11 architecture (so I can freeze processes on Pi ZereoW IOT devices). It looks like there is a bug in the bitops.S assembler code. ARM 11 is a classic ARM architecture and executes all instructions "in order". This means that the instruction dmb ish (set ...

Re: Csh script to bring up wireless lan

Here is a sister script which automatically attempts to re-connect network interfaces when the connection fails. Again, apologies for csh script. The usage is simple: iface_reconnect <interface> <poll time> <interface> is wlan0, eth0 etc, <poll time> is the time in seconds between successive connect...

Csh script to bring up wireless lan

Here is a relatively simple script which I have been using to control my RPI WLAN over the last few months. Sorry its a csh script - I've never liked sh (in all my 30+ years as a UNIX programmer!) - but it should be easy enough to adapt should anyone wish to do so. The script can set up managed and ...

Re: raspbian: ifconfig <interface> down - does nothing

Ok - I have an ad hoc network running - I found that if you do a sudo apt-get install iw and then run the following (tcsh) script, you can bring up an ad-hoc node on the rpi. This has been tested with the dongle supplied with the Maplin rpi kit and a Netgear ath9k dongle. For some reason, iwconfig d...

Re: raspbian: ifconfig <interface> down - does nothing

I am having exactly the same problem. It looks like the problem may be low level. As you say there are no error messages. I have tested the WLAN dongles I am using on other (x86 based) machines running a variety of Linux distros and evryhting works fine. Is this an issue with the rpi chipset or the ...
