**** BEGIN LOGGING AT Thu Jul 26 02:59:56 2007 Jul 26 15:42:27 anyone alive ? Jul 26 15:55:09 hi Jul 26 16:04:27 yes, and stuggling with jtag Jul 26 16:04:58 bflash has just acquired xilinx-type dongle support Jul 26 16:06:15 bflash ? Jul 26 16:06:37 jtaging software that can handle multiple chains, and emulate intel's jflash Jul 26 16:06:57 (in terms of command line) Jul 26 16:07:26 it's what we use on balloon because Dave Bisset reckoned none of the existing things were extensible enough Jul 26 16:07:45 once we have explunged the last bits of intel code it can be released GPL Jul 26 16:08:03 ah Jul 26 16:08:24 and it handles other flashtypes then strataflash ? Jul 26 16:08:34 I am having trouble with a selfmade wiggler interface... now i am wondering if i haev more success with the simpler xilinx cable... but this is using 5v, so are all jtag ports able to handle this ?? dont want to blow up my microcontroller ? Jul 26 16:10:31 the xilinx cable uses a buffer with the outputs powered by the target Jul 26 16:11:04 i meant the clone without the buffer... Jul 26 16:11:19 well actually the traget is a mips32 core Jul 26 16:11:48 p2-mate: it probably only handles what is on balloon2 and 3 so far Jul 26 16:11:49 I wouldn't skip the buffer Jul 26 16:12:11 if there's no buffer, it's not a wiggler Jul 26 16:12:12 I don;t think that is strataflash Jul 26 16:12:54 wookey__: you did the kernel support, so you ought to know those things :) Jul 26 16:13:04 i know... the wiggler cable i built has a buffer, but when i use ocd-commander it complains about "target not connected" Jul 26 16:13:10 I'm using this circuit: http://balloonboard.org/hardware/JTAG/xilinx/jtag_dongle_schematic.PDF Jul 26 16:13:23 that is equivalent to a wiggler isn't it? Jul 26 16:14:54 similar Jul 26 16:15:19 I believe so yes Jul 26 16:17:45 and is it better to call that 'wiggler' or 'xilinx' in a command-line option identifier? Jul 26 16:17:55 or perhaps allow both? Jul 26 16:18:29 different cables use different parport signals for different things Jul 26 16:18:49 I know - its a right pain in the bum Jul 26 16:20:33 we've been using LART/JTUX dongle on CPU channel and wiggler on CPLD/FPGA channel for last few years which is ridiculous state of affairs - now fixed this week :-) Jul 26 16:22:16 because of software incompatibilities? Jul 26 16:23:00 wookey__: so you needed a PC with 2 parallelports ? :) Jul 26 16:23:45 that's not hard to do Jul 26 16:24:54 on a laptop ? :) Jul 26 16:25:18 the built-in and a pcmcia card Jul 26 16:25:53 if the laptop still has pcmcia Jul 26 16:26:27 if it still has a parport, it still has pcmcia Jul 26 16:26:44 or a parallel port switch Jul 26 16:30:54 i wouldn't bother with a switch; just plug and replug. if that got too annoying, i'd use two laptops Jul 26 16:34:56 the problem with constantly pluging in and removing things is you get contact wair , and replacing the connector can be an expencive job, usualy after 1000 to 2000 insertions Jul 26 16:36:08 not if you use a 30cm parallel port extender that can be replaced Jul 26 16:36:54 oh, wait. you meant the male end Jul 26 16:37:52 no the female end suffers Jul 26 16:38:09 the extender fixes that Jul 26 16:38:14 true Jul 26 16:38:50 actually, it could fix either situation Jul 26 17:15:41 * drath wonders if blasti99 knows about the connection between two parport pins that are used to identify "genuine" wigglers Jul 26 17:16:48 d'oh! **** ENDING LOGGING AT Fri Jul 27 02:59:56 2007
