CRC.pm error on ARM

[BasvanH]

Hi Lieven,

I’m busy integrating your xpl-plugwise work on a QNAP NAS (with ARM cpu). I think I’m almost there, but I’m bumping on an error when starting the xpl-plugwise. The perl environment meets the prerequisites and XPL-Perl is compiled. I start the xpl-hub and xpl-logger and then I start the client like “/opt/bin/xpl-plugwise –verbose –plugwise-tty /dev/ttyUSB0”. Then I get this output: Listening on 192.168.1.253:59326 Sending on 192.168.1.255 Use of uninitialized value in subroutine entry at /opt/lib/perl5/site_perl/5.10.0/arm-linux/Digest/CRC.pm line 264. WR>STICK: 000AB43C

When I want to list all the connected cicles, the xpl-plugwise outputs this: Use of uninitialized value $address in substr at /opt/lib/perl5/site_perl/5.10.0/xPL/Dock/Plugwise.pm line 954. Use of uninitialized value in subroutine entry at /opt/lib/perl5/site_perl/5.10.0/arm-linux/Digest/CRC.pm line 264. WR>STICK: 0026000D6F0000000000B034

I get no xpl-stat back. (hub see’s everything’s connected, xpl-logger see’s the request going by). So I think the CRC.pm is the problem. Do you have any idea’s what could be the cause?

This is the part round line 264 of CRC.pm: sub crc { my ($message,$width,$init,$xorout,$refout,$poly,$refin,$cont) = @_; _crc($message,$width,$init,$xorout,$refin,$refout,$cont,_tabinit($width,$poly,$refin)); <<<THIS }

Thanks in advance (have a great 5th of May liberation day).

Best regards, Bastiaan

Hi Lieven,

via your website you asked me to do a perl trace on the CRC module and capture the parameter uninitialized. I'm not very familair with Perl debugging, so could you give me some direction perhaps?

Thanks and regards, Bastiaan

Hi Bastiaan,

the most easy way is to add a

print "$variable\n";

statement just in front of the function call. If you do this for all variables that are passed to the function then you should get an error on the line where you try to print the variable and then you know who the culprit is.

Kind regards, Lieven.

Hi Lieven,

I got it solved. I used the cpan of the IPKG repository, but it was kind of out dated. So I updated it and run a re-install of all modulles. Now I can get readings out of the plugwise network. So thats very great!

I stil do have the CRC.pm errors on the xpl-plugwise side. Don't know if they can be safely ignored?

Hello Bastiaan,

good news that you can retrieve values from the plugs. What version of the firmware are you running, because the 'unknown response' messages you get at the end of the log are new to me.

Kind regards, Lieven.

[BasvanH]

Hi Lieven,

Most of my plugs are fw dated 2011-05-13, some are 2011-06-27, and i got a Switch, Sense and Scan module also. Perhaps those sensor module are giving these 'unknown response' messages?

Regards, Bastiaan

[hollie]

Hello Bastiaan,

aha: I have only circles, so probably the 'unknown' messages indeed originate from the switch/sense/scan modules.

If you are able to decypher the messages, we can add support to the xpl-plugwise module for them.

Kind regards, Lieven.

Hi Lieven,

Well, I started the project because i wanted to develop on PHP, and not the builtin webserver of plugwise. I'm kind of lucky that I've managed to get the xPL working on my NAS. I'm ok with PHP and MySQL. But perl and reverse enginering of the plugwise protocol via RS232 ext is not my cup of tea.

I take it you are dutch to, so if you want I can capture some stuf for you to analyze. We can mail if you want b.vanhaastrecht( a )gmail.com . Otherwise goedemiddag :-)

Thanks for the work, Bastiaan
