[nslu2-linux] Re: Help with IceS - PERL quesion

 

http://trac.nslu2-linux.org/optware/changeset/11582

(took a little hack in adding the perl support because of cross compilation)

Our autobuilder is having some problem. So the ipkg won't appear in the feeds for a few days.

If you cannot wait, try setup a build environment and build the ipk binary yourself. Or ask some one to build it for you.

Regards,

-Brian

[nslu2-linux] Accessing the on-board GPIO

 

I am using Slugosbe v5.3 in a slug.

The Xscale chip provides 16 GPIO connections, and nominally these are all used by the slug. Each provides facilities for input and/or output of one bit, plus the facility to cause a user-catchable interrupt upon input.

However, we know perfectly well that slugos does not use them all. For a start, the two 'disc' leds are not used, and are in principle available for other hacks. Moreover, I am planning to implement the ForcePowerAlwaysOn hack, which means the power button and its green light are also available (indeed, by the time my slug has been embedded, there will be no way to press the power button even if you wanted to). I also intend to bring out the i2c bus, and what I want to do is to arrange that an interrupt can be sent back from the i2c bus (a facility provided by the bus expander ship I intend to use) so that, when a button is pressed an interupt will be generated and caught, avoiding the need to run a continuous polling loop.

So the question is: is there some way within Slugos to interact directly with the GPIO (there must be some such mechanism somewhere, because the publicly accessible i2c interface must use it, but it might be well concealed within the system). For sure that would be the neatest way to implement what I want.

But if that is not possible (without writing special Slugos drivers, which I would prefer to avoid), would the following ghastly hack work?

The plan is to connect the interrupt signal from the i2c bus so that it effectively "presses" the unused power button (The INT signal is just a simple 'pulldown'). Currently, when that button is pressed, the ensuing interrupt is caught and causes a call to 'shutdown -h now'. So I shall simply remove shutdown (specifically shutdown.sysvinit) from /sbin and replace it with a script of my own choosing.

Indeed, I have tried this, and pressing the button duly called my script, and the slug continued running regardless.

And finally, if I do shut down the slug (by pulling the power plug, or when there is a power cut), is there some way to cause it to die graceffully. Presumably, a large capacitor across the 5V supply would be neede to buy time, but would I also need to tell it what was afoot, or would the cpmplicated power control system automatically do that for me (maybe that would simply call my "script", but I could probably detect that somehow)?

[Java] Re: Facing issue with BufferedWriter

 

My apologies,

I was thinking backwards flushing before the write call. Changing the event
order solved my issue.

[Java] Facing issue with BufferedWriter

 

Hello,

I'm facing an issue while playing with BufferedWriter: got a loop with ten
iterations. Debugging through the console via System.out.println, I can see
the 10 lines it was supposed to display. But when I call the
BufferedWriter's write() method, the last line isn't written.

I'm not sure where the problem is. Can anyone help me with a workaround?

Current Output:

> Case #1: 2 3

Case #2: 1 4

Case #3: 4 5

Case #4: 29 46

Case #5: 11 56

Case #6: 4 5

Case #7: 40 46

Case #8: 16 35

Case #9: 55 74

Desired Output:

> Case #1: 2 3

Case #2: 1 4

Case #3: 4 5

Case #4: 29 46

Case #5: 11 56

Case #6: 4 5

Case #7: 40 46

Case #8: 16 35

Case #9: 55 74

Case #10: 7 9

The message is telling the truth :) So either your network cable is
damaged, or the NSLU2 is not on the same network as your host (the
upgrade protocol will not pass through firewalls or through routers
(this means *through* a router, it passes freely between the various
ports on the switch built into the typical home router/firewall
appliance)) -- or your NSLU2 is not, in fact, in upgrade mode.

How did you enter upgrade mode?
-Mike (mwester)

 
Powered up with reset button depressed.

The two machines are attached to different interconnected switches. This may be at the core of the problem and I will investigate this as soon as I get a chance.

Thank you very much for the information. I'll update the list as soon as I get the chance to try both machines on the same switch.

Re: [nslu2-linux] Help with IceS - PERL quesion

 

   I'm guessing whoever compiled Ices 0.4 for the unslung ipkg feed may not get these messages from the Yahoo group.

I've successfully installed Ices0 (0.4-1) from the ipkg feed for unslung. However, when I attempt to use ices with the PERL module I have, I receive this message:

A quick search on this error reveals that I may be looking at a re-compile:

I know Ices does work on my Slug without attempting to use the PERL module, as I've tested it with Icecast, and it works fine.

Please, please - would it be possible for the maintainer of the ipkg feed to add in support for PERL to Ices0?

It all feels so very, very close...
