Re-sent cos this PC defaults to Rich Text. Sorry Admins. From: keithjamieson(a)hotmail.co.uk To: main(a)lists.alug.org.uk Subject: RE: [ALUG] JTAG Date: Thu, 28 Apr 2011 18:05:28 +0100 Mark JTAG is used to use a PC to program an embedded device. I have made one the parallel port of a PC to recover my Linksys WRT54G. It also, I think, can be used to debug the device. Its a "standard" which is adopted by manufactured, althought I have not heard of the newer one you mentioned. But I have not been in this field for some time! In the older times you would remove an EEPROM and pur it into a programmer, then put it back into your device. This is the lead to illiminate that need. Keith

Changing the location of an SVN repo
by Mark Rogers 10 May '11

10 May '11

Assume I have an SVN repo accessed via http at http://svn.example.com/svn/myapp. The URL http://svn.mycompany.com/svn/myapp is an alias for the above (ie same server, same login details). How do I tell an svn client that's already checked out a working copy to use the new URL given that nothing apart from the URL is changing? As an aside, if the new URL was on a different server with different user/pass but contained an identical repository (with a view to moving to a new host), how would that affect things? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Is there anything 'ready made' to add suffixes to ordinal numbers (in dates in particular)?
by Chris G 09 May '11

09 May '11

I'd like to output dates like:- 1st September 2009 23rd August 1967 I.e. I want the 'st' and 'rd' suffixes for the day. It doesn't look like strftime() offers an option to do this. I can obviously do it myself with a switch/case or some if/then/else statements but I was wondering if there's anything ready-made that I've missed. -- Chris Green

The 'Elite' Man
by Chris Walker 09 May '11

09 May '11

If anybody here remembers David Braben, he's active again with something different from Elite. Take a look at http://www.raspberrypi.org/ When I looked at it, I had in mind Chris Greens webcam on his boat and whether something like this could be used. -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:cdw_alug@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

TCP/IP logging
by Mark Rogers 09 May '11

09 May '11

I have a simple application which connects to port 50000 on a Linux box, communicates, then disconnects. I'd like to log the entire communication in each direction in an easy-to-read format so that I can see what is going on. The protocol is ASCII but with a few control chars thrown in (eg STX/ETX/ACK/etc, and I wouldn't like to rule out NULL chars ever appearing in the data). I can easily run the server side at (say) port 50001 instead and have "something" listen on port 50000 and connect to port 50000 and pass the data back and forth between the two, logging it as it goes, although I don't know what to choose for "something". Or I could look at Wireshark, which I've played with in the past but never in anger, and my general feeling is that unless I learn how to sort the trees from the wood then this is going to give me too much information and I'm going to spend more time sorting through it than I do resolving the issues in the protocol. Or maybe there are better alternatives altogether! [If it's relevant: the Linux server has no GUI but is a VirtualBox virtual machine on another Linux server that does have a GUI where I could run Wireshark. The device connecting to the server is not a PC and has no diagnostic capability built in.] -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

where is allegro?
by Chris Walker 06 May '11

06 May '11

Perhaps somebody can point me in the right direction as I'm getting nowhere searching online. I'm trying to compile rpcemu as per this site - http://www.riscos.info/index.php/RPCEmu_Linux_Guide I grabbed everything before the marutan site disappeared. The error I'm getting is ./configure: line 4557: ` AM_PATH_ALLEGRO(, , as_fn_error "building RPCemu requires Allegro to be installed" "$LINENO" 5)' My system is Mandriva 2010 64 bit in case that's important. If I do 'urpmi -a Allegro' it tells me 'Packages lib64allegro4.4-4.4.1.1-1mdv2010.1.x86_64, allegro-jack-plugin-4.4.1.1-1mdv2010.1.x86_64, allegro-4.4.1.1-1mdv2010.1.x86_64, lib64allegro-devel-4.4.1.1-1mdv2010.1.x86_64 are already installed' but looking for the cause of the error, I found this 'This comes about because aclocal cannot find allegro.m4.' on here - http://wiki.allegro.cc/ If I look in the places pointed to by that error, allegro.m4 is nowhere to be found and it's not found by Dolphin when I do a search. What am I doing wrong? -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:cdw_alug@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

Scammers – google them and you get several forum posts about them (after their actual page natch) See http://www.domainscams.co.uk/domain-name-scammer_42_Domain-Renewal-Group.php They probably sell ‘domain theft’ insurance as well… ☺ Regards, Mark Fernandes http://codingscience.blogspot.com/ http://bbn.ifrn.bbsrc.ac.uk/gary/main.html http://www.ifr.ac.uk<http://www.ifr.ac.uk/> When you can measure what you are speaking about, and express it in numbers, you know something about it.

JTAG
by Mark Rogers 28 Apr '11

28 Apr '11

Looking at some of the embedded Linux units, eg the GuruPlug that I have sat on my desk and have never got around to playing with, a lot of them mention JTAG. It's been a long time since I played with this type of kit and it seems that things have moved on from the days of UV lamps for wiping EPROMs, but I can't find anything useful but short about what JTAG is/does and whether JTAG is just JTAG or it's one of the standards that require you to pick the right JTAG programming kit to match the hardware. Anyone around these parts able to give me a quick intro, or point me to one? At this point I really just want to know whether it's even something I need to know about! The High Level guide here: http://www.xjtag.com/support-jtag/jtag-introduction.php .. looks great but is still a little to low level for me at this stage! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG
