| 13:46.22 | prpplague | man openocd is really gone to hell in a hand basket |
| 13:47.43 | Kebianizao|work | prpplague: what do you mean? |
| 13:50.17 | prpplague | Kebianizao|work: the current openocd is completely bloated, over engineering with useless features, and just about completely unusable |
| 13:50.42 | Kebianizao|work | prpplague: heh! I find it useful |
| 13:50.52 | Kebianizao|work | what useless feature you can think about? |
| 13:51.30 | prpplague | Kebianizao|work: it would take me an entire week to go over it all |
| 13:51.54 | Kebianizao|work | I have the time :) (just kidding) |
| 13:52.10 | prpplague | yea but i don't, atleast not this week |
| 13:52.43 | Kebianizao|work | prpplague: have you expressed your opinion in the ML, I think opinions like yours are welcome |
| 13:53.06 | Kebianizao|work | and you don't need to give the full list, you can start with what you find worst |
| 13:53.33 | Kebianizao|work | it's clear that they won't change it upside down, but still some comments may be useful |
| 13:53.50 | prpplague | Kebianizao|work: yes i have, i've given up on that |
| 13:54.39 | Kebianizao|work | oh, could you point me to that? I would like knowing. I guess approx date is enough |
| 13:55.11 | prpplague | august/september of 2008 |
| 13:55.32 | Kebianizao|work | I see, thanks |
| 13:55.54 | prpplague | drath been in the channel lately? |
| 13:56.10 | Kebianizao|work | quite new here, sorry I couldn't tell |
| 13:56.17 | prpplague | ahh |
| 14:01.45 | Kebianizao|work | a pity but I've bee unable to find your e-mail in the ML archive :S |
| 14:03.57 | prpplague | oh well doesn't really matter anyway, we have a fork of one of the older versions |
| 14:04.35 | prpplague | just that we get inquires every once in awhile about using the yagarto openocd version |
| 14:08.11 | Kebianizao|work | prpplague: is that fork available? |
| 14:09.17 | prpplague | http://www.elinux.org/images/8/80/Openocd.tar.gz |
| 14:14.08 | Kebianizao|work | do you maintain that as open source? I mean do you have a tracker, repository? do you snapshot openocd or also add some changes? |
| 14:16.35 | Kebianizao|work | at first sight I miss tcl which I guess is part of you define as bloat |
| 14:17.43 | prpplague | Kebianizao|work: yes we have a repo, and yes tcl is a major part of the bloat |
| 14:18.59 | Kebianizao|work | I don't want to abuse your time, but if you consider your fork world (re)viewable I'd like having a link. I'm quite curious about it |
| 14:20.33 | prpplague | Kebianizao|work: not as of yet, thats the reason i joined the channel today, i used to hang out here with drath in the good old days, and i need to double check with him a few things before making it available |
| 14:20.54 | Kebianizao|work | ah, that's ok |

| 18:11.59 | drath | "completely sick" is probably among the nicer things i could say about the current openocd state ;) |
| 18:12.05 | prpplague | drath: what cooking over in your neck of the woods? |
| 18:12.15 | prpplague | drath: hehe |

| 18:15.05 | drath | prpplague: is it ok if we discuss this topic here? or would you prefer an email? |
| 18:15.21 | prpplague | drath: here is fine for me |
| 18:16.33 | prpplague | drath: basically we are looking at rolling back to around the end of 2007 for version |
| 18:16.59 | prpplague | drath: fix all the know issues with that rev so it is stable |
| 18:17.22 | prpplague | drath: do a release, and then use that as a basis for improvements/changes |
| 18:17.59 | drath | prpplague: yeah... it's been far too much "reworking" for questionable reasons, and dozens of new features/technologies without caring about improving the existing codebase... |
| 18:18.42 | drath | prpplague: did you or the other folks you mentioned try to express your concerns on the list? |
| 18:19.16 | drath | prpplague: the situation has been rather problematic for me, as i don't have time to contribute myself, so it's hard to stop those who are contributing |
| 18:19.50 | prpplague | drath: yea back in august/september of 2008 when i was doing some of the work on the cortex-a8 and icepick dev |
| 18:20.51 | prpplague | drath: i had a couple conversations with the current maintainer |
| 18:21.40 | prpplague | drath: it's just that i think all the changes, new features and re-works have gotten out of control |
| 18:26.39 | drath | prpplague: yeah, definitely... i don't think you'll be able to convince oyvind to change the current development, so a fork might really be necessary... it would be nice if you could keep me posted, maybe we can eventually bring both lines of development back together one day |
| 18:27.27 | prpplague | drath: right, i was considering using either the linuxtogo.org site or getting a repo up and running on the elinux.org site (CELF sponsored) |
| 18:27.37 | prpplague | drath: you have a preference? |
| 18:28.24 | drath | prpplague: whatever suits you best |
| 18:28.59 | prpplague | drath: probably go with the linuxtogo.org site if it isn't too difficult to get setup |
| 18:29.37 | drath | prpplague: i suppose a branch on the original openocd site would cause too much confrontation, otherwise i'd offer you admin access there |
| 18:30.48 | prpplague | drath: yea i think that would be problematic, and based on the incidents with the GPE stuff, it might make more sense to be seperate |
| 18:43.55 | drath | prpplague: allright, gotta go... i'll try to check by every once in a while |
| 18:44.01 | drath | prpplague: bye |
| 18:44.14 | dirk2 | sorry, but any hint about which target architecture/board you are talking here |
| 18:44.22 | dirk2 | ? |
| 18:45.37 | prpplague | dirk2: hehe, openocd in general |
| 18:46.58 | dirk2 | yes, ok, I got this ;) Any special target in mind? Seems that Dave is helping a little with TI stuff, btw |
| 18:48.36 | prpplague | dirk2: dave who? |
| 18:49.10 | dirk2 | David Brownell |
| 18:55.58 | prpplague | ahh |
| 18:56.11 | prpplague | dirk2: no special target in mind |
| 18:56.25 | *** join/#openjtag _julian (n=quassel@dslc-082-083-153-168.pools.arcor-ip.net) |
| 18:56.36 | prpplague | dirk2: just a number of us are very unhappy with the overall direction that openocd is headed, including drath |
| 19:02.56 | prpplague | dirk2: when the TCL stuff was added and they started changing the config file structures, thats when everything started going down hill |
| 19:07.08 | dirk2 | ok. my hope is that it will calm down some time and that somebody with the time and knowledge will help |
| 19:09.20 | prpplague | dirk2: for which item? the cortex-a8/icepick stuff? |
| 19:10.50 | dirk2 | prpplague: Yes, OMAP3. Icepick seems to be basically solved. Cortex A8 is missing, though. There are some scripts that can do already a lot with Cortex A8, but converting them to some legacy OpenOCD (C-) code and adding the missing stuff (cache, MMU) is still missing |
| 19:11.10 | prpplague | dirk2: ahh |
| 19:11.30 | prpplague | dirk2: i've lost all interest in the beagle |
| 19:11.44 | prpplague | dirk2: (not that i had that much to start with) |
| 19:12.11 | dirk2 | prpplague: and, you are right, as soon as we have something working, it is broken by some new changes again, and the comment is then "your previously working code was wrong" |
| 19:12.24 | prpplague | dirk2: yep |
| 19:16.27 | dirk2 | unfortunately, none of the core developers seem to be here often. Instead, you get sometimes ~100 mails from mailing list per day, not able to track them |
| 19:16.37 | prpplague | yea |
| 19:17.08 | prpplague | dirk2: mailing list has it's usage, but for something that is moving as fast as openocd has been, interactive conversation tends to be better(IMHO) |
| 19:18.48 | dirk2 | anyway, good luck with your fork, bye |
| 19:20.45 | prpplague | dirk2: later bud |
| 19:20.52 | prpplague | waves bye to dirk2 |

| 20:57.33 | Zoiah | Is there any JTAG tool that supports FT2322 (Olimex ARM-USB-OCD), Motorola MPC8245 and 2 Intel Strataflashes 8x wired in 16x, using the memory mapped flash instead of having to figure out which pins the flash is attached to exactly? |
| 20:59.09 | prpplague | Zoiah: i'm not familiar with the MPC8245, what is that a MIPS core? |
| 20:59.40 | Zoiah | It's a PPC core. |
| 21:00.11 | Zoiah | I often found it in networking equipment and some small storage things. |
| 21:00.35 | prpplague | Zoiah: ahh, you will probably have trouble getting that to work via jtag without some serious docs |
| 21:00.57 | Zoiah | UrJTAG supports MPC824x just fine, but not the 2 x8 in x16 setup. |
| 21:02.13 | prpplague | Zoiah: ahh, was unaware of that |
| 21:02.51 | prpplague | makes a note to get the latest UrJTAG |
| 21:03.00 | Zoiah | I got pointed at TopJTAG which is a closed-source Win32 application, but that uses pintoggling directly to the flashchip. |
| 21:03.17 | prpplague | ahh |
| 21:03.23 | Zoiah | And I do not have schematics of my devices (3com 3870, edgecore es4549, dell powerconnect 3324), so this is probably not feasible for me. |
| 21:04.19 | Zoiah | All these devices use the same OEM and basic structure (MPC8245 behind JTAG COP pinuot and 2 PLDs behind PLD JTAG pinout). |
| 21:05.31 | roxfan | urjtag only does boundary scan, but i guess you don't need debugging here |
| 21:05.56 | Zoiah | UrJTAG does flashing through memory i/o in the cpu core. |
| 21:06.11 | Zoiah | So if you know where your flash is mapped into memory, you can flash that way. |
| 21:06.32 | roxfan | hmm it does? that's new |
| 21:07.21 | Zoiah | Openwince also did this. |
| 21:07.27 | Zoiah | http://buffalo.nas-central.org/wiki/JTAG_Software/Openwince |
| 21:08.41 | roxfan | this looks to me like boundary scan... |
| 21:10.39 | Zoiah | Yes, it uses boundary scan to do memory i/o to the CPU. |
| 21:12.42 | Zoiah | I am new to these kinds of things, so I might be using the wrong terms. :) |
| 21:12.52 | roxfan | i think it just toggles pins connected to the flash |
| 21:13.16 | roxfan | at least that's what was happening when i tried it a year or so ago |
| 21:13.22 | Zoiah | How would it know to which pins the flash is connected? And why would it require the location in the memory of the cpu? |
| 21:14.12 | Zoiah | Because if UrJTAG knows to which pins it's connected, I could feed that information to TopJTAG maybe. |
| 21:15.43 | roxfan | well, the pin descriptions are specified in the BSDL file |
| 21:16.34 | roxfan | so you basically need to mimic the signals on them as if the cpu is reading or writing data |
| 21:16.44 | Zoiah | The pins of the cpu, but i can imagine there's more than 1 way to wire a flashchip to a chip. |
| 21:17.20 | roxfan | yeah, often it gets tricky |
| 21:18.36 | Zoiah | So, because the location of the flash chip in the memory is defined, I assumed it was doing memory i/o on the cpu. |
| 21:18.48 | Zoiah | That should be possible, right? |
| 21:19.04 | Zoiah | http://www.youtube.com/watch?v=JhojoT1o1M4 |
| 21:19.09 | Zoiah | Sorry, did not mean to paste that. |
| 22:11.32 | prpplague | man o man i wish i could find an old copy of openocd for winblows |

| 22:19.24 | prpplague | oh dandy, thanks |
| 22:19.35 | prpplague | roxfan: you have anything closer to R734? |
| 22:20.08 | roxfan | not at the monent |
| 22:20.12 | roxfan | but i'll look around |
