| 02:00.51 | flyback- | going to go wash down some old motherboards etc bbl |
| 02:01.04 | flyback- | but value your opinion |
| 02:03.36 | landley | prpplague: I just put out a tinycc-0.9.25-pre1 release. :) |
| 02:03.47 | landley | Alas, the arm target isn't enabled yet. |
| 02:03.55 | landley | Just i386. |
| 02:04.41 | landley | I should have arm working in the next few days, but getting i386 to both pass the test suite and build itself seemed like a good checkpoint. |
| 02:05.29 | flyback- | nice |
| 02:06.50 | prpplague | flyback- do not do that again |
| 02:06.58 | prpplague | landley greetings |
| 02:07.02 | flyback- | yes mam |
| 02:07.13 | prpplague | landley cool deal |
| 02:07.20 | prpplague | landley definetly looking forward to it |
| 02:07.37 | flyback- | landley: |
| 02:07.44 | flyback- | since you seem to know pc hw well |
| 02:07.53 | landley | Ooh, there's a dangerous assertion. |
| 02:08.00 | flyback- | how does a intel i845 chipset compare to a 440bx in terms of ide stability etc |
| 02:08.09 | flyback- | this is for a recovery pc |
| 02:08.13 | flyback- | for puilling data from old hd's etc |
| 02:08.30 | flyback- | i was just going to use a p2 and 440bx but that celeron board and cpu I have is ready to go just needs 5 cpu caps |
| 02:08.53 | landley | I've heard bad things about both. |
| 02:09.05 | flyback- | well 440bx is well tested :P |
| 02:09.10 | landley | Personally, I tend to buy the cheapest plastic crap I can, and then make it work via lots of growling at it. |
| 02:09.23 | flyback- | I don't trust that shit for this project :) |
| 02:09.49 | landley | If you're going for stability, buy something that runs cool. |
| 02:10.17 | flyback- | cooling I am not worried about |
| 02:10.29 | flyback- | it's ide controllers that "well sorta" work |
| 02:10.38 | flyback- | *COUGH* via's early S*** *COUGH* |
| 02:10.44 | landley | I mean something that doesn't need a fan on anything but the CPU. (And if you can get a fanless CPU, it's worth the performance hit). |
| 02:11.03 | prpplague | landley so you think getting the arm target up won;t take too much? |
| 02:11.09 | flyback- | ugh |
| 02:11.22 | flyback- | prpplague: |
| 02:11.23 | landley | I haven't heard of problems with an Intel IDE controller in... about seven years? |
| 02:11.24 | flyback- | quick question |
| 02:11.28 | flyback- | for small cell phone size lcd's |
| 02:11.29 | landley | Ever since Intel started providing good docs. |
| 02:11.34 | flyback- | how bad is stn driving |
| 02:12.10 | flyback- | sclk and sdata |
| 02:12.29 | landley | prpplague: it shouldn't. |
| 02:12.47 | landley | The main problem is that the configuration wants all upper case symbols and I've been giving it mixed case. |
| 02:13.08 | landley | It's mostly that cutting a -pre1 is cheap enough I don't want to delay it for something that could easily turn into a 5 day debugging session. |
| 02:13.19 | landley | Since I have no idea what shape arm is _in_, not having tested it in forever. |
| 02:13.33 | landley | That said, I have no reason to think it's broken from the last time it worked, except for bit-rot. |
| 02:13.54 | landley | This is why I'm ripping out the old build, by the way. |
| 02:14.10 | landley | "You didn't specify a target? Let me provide a default value, with no error!" |
| 02:14.33 | landley | The ./configure doing that is one thing. |
| 02:14.43 | landley | The C code doing it in #defines is something else entirely. |
| 02:14.56 | landley | So... much... cleanup. |
| 02:15.04 | prpplague | interesting |
| 03:10.58 | flyback | prpp? |
| 03:12.36 | prpplague | flyback yes? |

| 03:16.32 | prpplague | flyback you have me totally lost |
| 03:16.40 | flyback | ok |
| 03:16.53 | flyback | you remeber how we have discussed lcd driving before |
| 03:17.03 | flyback | and generally the stn ones are not worth the hassling |
| 03:17.13 | flyback | to generate all the signals and timing etc |
| 03:17.14 | prpplague | not sure that i said that |
| 03:17.20 | prpplague | but ok |
| 03:17.26 | flyback | ugh |
| 03:17.27 | flyback | nm then |
| 03:17.32 | flyback | I guess I am just senile |
| 03:18.22 | flyback | lemme put it this way |
| 03:18.22 | prpplague | flyback if you are refering to you lcd from a cell phone |
| 03:18.28 | flyback | yes |
| 03:18.30 | flyback | in this case |
| 03:18.39 | prpplague | flyback then yea, the pinout you posted is most likely a modified spi interface |
| 03:18.41 | flyback | signals are only sclkc and sata |
| 03:18.55 | flyback | how painful would it be to drive one from a parallel port |
| 03:19.04 | prpplague | no problem at all |
| 03:19.12 | prpplague | a standard jtag dongle will do it |
| 03:19.14 | flyback | the hadest part appeaes to be getting the 74xxx series chip to convert +5 to +3.3 :P |
| 03:19.23 | prpplague | just use a jtag dongle |
| 03:19.29 | flyback | don't have one :P |
| 03:19.40 | prpplague | flyback buy one, they are cheap |
| 03:20.01 | flyback | I wanna get this one going in the next fe days mabye even tomarrow |
| 03:20.21 | prpplague | are you sure its 3.3v? |
| 03:20.30 | prpplague | most of the cell phone lcd;s are 1.8v |
| 03:20.32 | flyback | well the vcc is 3.2 |

| 03:22.46 | flyback | already got the lcd torn down to just glass and the copper foil |
| 03:22.59 | flyback | have to figure out a) how to solder up like 4 wires to the foil without damage |
| 03:23.18 | flyback | and b) how to project bright light thru it say a halogen without biuling it |
| 03:23.21 | prpplague | uh, not gonna happen, why didn;t you save the connector? |
| 03:23.23 | flyback | probably just a big ass fan |
| 03:23.36 | flyback | the foil is the connector |
| 03:24.02 | prpplague | yea its got to have connected to the pcb somehow |
| 03:24.18 | flyback | the pcb is the foil :) |
| 03:24.39 | flyback | i;d show you a pic but my cam ran out of batteries :/ |
| 03:24.43 | prpplague | you telling me the pcb for the phone is a flex? |
| 03:25.04 | flyback | well the lcd pcb,chip is flex |
| 03:25.09 | flyback | once you removde it from the backing |
| 03:25.33 | prpplague | ahh you gonna have a rough time soldering to that |
| 03:25.51 | flyback | well I could use glue |
| 03:25.59 | flyback | conductive |
| 03:26.00 | prpplague | i'd have to see the flex to see a good point to solder to |
| 03:26.05 | flyback | only need 5 wires |

| 20:51.15 | hapchap | MothaWork: ? |
| 20:52.29 | MothaWork | we've got the kernel booting to a complaint about a lack of root filesystem (which makes sense: there is none), but no serial port output |
| 20:54.05 | hapchap | MothaWork: default console set in the kernel command line? |
| 20:54.08 | adyer | umm, where is the complain message showing up if there's no serial? framebuffer? |
| 20:54.21 | hapchap | MonMotha: what bootloader? |
| 20:54.34 | MothaWork | adyer: the only reason we know it's booted to the root fs panic is a remote debugger |
| 20:54.41 | MothaWork | hapchap: u-boot, which does work including serial output |
| 20:55.00 | hapchap | but once you execute the kernel, no more output? |
| 20:55.05 | MothaWork | correct |
| 20:55.25 | hapchap | can you change the kernel command line in uboot? |
| 20:55.33 | adyer | mothawork if you have a debugger can you look at the printk output buffer to seee what's logged in there? |
| 20:55.47 | MothaWork | hapchap: yes, and we've tried all 4 ttyS options |

| 20:57.27 | MothaWork | there's an option for "Install device as ttyATn instead of ttySn", which is not selected |
| 20:57.31 | adyer | look in the printk buffer for the serial driver registration msg |
| 20:57.56 | hapchap | also, make sure you dont put a path on the console=" |
| 20:58.08 | hapchap | i.e. "console=ttySAC0 root=/dev/ram0" |

| 21:30.44 | prpplague | landley: hehe |

| 21:32.09 | MothaWork | point taken |
| 21:32.12 | landley | Eh, that's probably a bit strong. |
| 21:32.32 | landley | Then again, "much" is already a qualifier... |
| 21:32.33 | MothaWork | s/good.*/much/ |
| 21:32.45 | MothaWork | or how about s/good.*/ever/ |
| 21:32.53 | MothaWork | or perhaps s/good/.*/useful/ |
| 21:32.59 | landley | Not going there. |
| 21:33.01 | MothaWork | er, I had a stray /, but you get the idea |
| 21:33.17 | landley | I wrote a replacement to udev once, and I need to revive it and make it do everything I want it to do. |
| 21:33.28 | MothaWork | I just finally redid my desktop to use it a few months back because I finally needed a driver that needed the runtime firmware downloading |
| 21:33.44 | landley | The downside of having six projects going at once is you can swap-thrash if you're not careful. |
| 21:33.52 | prpplague | MonMotha: hey, you done any circuits powered by a li-ion batteries that include in-circuit charging? |
| 21:34.03 | MothaWork | prpplague: can't say that I have, though Maxim has some app notes |
| 21:34.17 | prpplague | MonMotha: ahh, i'll have a look |
| 21:34.40 | adyer | I have one Li+ board and have looked at others |
| 21:36.22 | prpplague | adyer: oh? any references you can point me towards? |
| 21:38.28 | adyer | you'll need a battery spec to set max chage current and charge termination conditions and timeouts. I used ISL6253 as a charger, works well, but doesn't include much status or charge timers |
| 21:39.07 | prpplague | adyer: i'm more interested in how the switch over between battery powered and charger+external power |
| 21:39.49 | adyer | the ISL6253 has switching logic built in, just a couple of p-fets |
| 21:40.12 | prpplague | adyer: hmm, so the ISL6253 has the switch over built in? |
| 21:42.15 | adyer | we've also used LTC4007 and a maxim chip (forget which one) a while ago. |
| 21:42.37 | prpplague | hmm, whats the max charge current of the ISL6253? |
| 21:43.32 | adyer | mostly depends on external components, inductor, sense resistor, feedback. I think they had a 6A reference design |
| 21:43.50 | prpplague | hmm |
| 21:43.55 | prpplague | adyer: whats the cost of that part? |
| 21:44.13 | adyer | web price is $2.26/1K |
| 21:44.46 | adyer | intersil has pricing on the web site for 1K |
| 21:45.35 | prpplague | hmm |
| 21:48.51 | prpplague | adyer: so based on the schematics i'm looking at, the ISL6253 handles the switching |
| 21:53.51 | adyer | yes, when the incoming charging voltage gets above a user threshold, the two gate signals change and power the load from the charging voltage |
| 21:55.12 | prpplague | adyer: and the battery is isolated for charging |
| 21:55.43 | prpplague | the only issue we'd have with this chipset is that we had hoped for charging via usb |
| 21:56.45 | MothaWork | we has serial output |
| 21:56.56 | MothaWork | the struct that maps serial ports on at91 is a bit wonky... |
| 21:57.22 | adyer | there are other more integrated chargers for single-cell batteries that have USB support. Ours is a two cell, so we skipped USB support |
| 22:02.20 | prpplague | adyer: yea we need an odd combo, max charge of 2.5A and support for usb charging at 500mA |
| 22:03.46 | prpplague | adyer: which ones would you recommend for a single-cell ? forget the usb charge support |
| 22:04.58 | hapchap | MonMotha: yay! |
| 22:07.33 | adyer | there's alot more choices for single cell, hard to say. They all seem to have 'features' |
