| 05:44.23 | bd2 | hi all. arm assembly question: I've got "Error: invalid pseudo operation -- `str r0,=0x100000'" on mentioned instruction. ldr instruction works fine. what is wrong with str? |
| 05:45.02 | bd2 | that is gcc-3.4.1. |
| 05:49.25 | bd2 | isn't something wrong with me? ;-) |
| 06:39.18 | davidc__ | bd2: er...... |
| 06:39.36 | davidc__ | ldr r0, =0x1000000 means load constant 0x100000 into variable r0 |
| 06:40.03 | davidc__ | the = syntax means allocate a chunk of memory that contains the variable 0x1000000 |
| 06:40.06 | davidc__ | er, value |
| 06:40.24 | davidc__ | and then use PC-relative addressing to load the address from |
| 06:40.37 | davidc__ | however, str r0, =0x1000000 makes absolutely no sense |
| 06:41.06 | davidc__ | because you'd be allocating space for the constant 0x10000000 |
| 06:41.11 | davidc__ | then writing r0 back into the space |
| 06:41.14 | davidc__ | which is an odd thing to do |
| 06:41.34 | davidc__ | I think you mean, ldr rN, =0x1000000, str r0, [rN] |
| 06:42.04 | davidc__ | however, you don't need to actually use the ldr = syntax for that because you can create a constant of value 0x10000000 to use in mov |
| 06:43.19 | bd2 | hm. that explains a lot. davidc__, much thanks! Can you recommend some good arm assembly reference, where such issues covered? |
| 06:44.27 | davidc__ | bd2: well, theres the ARM ARM - to start off with |
| 06:44.52 | davidc__ | then next maybe get the Arm System developers guide |
| 06:45.03 | bd2 | "ARM ARM"? |
| 06:45.12 | davidc__ | ARM ARchitecture Reference Manual |
| 06:45.27 | davidc__ | however, the = syntax is really a function of the specific assembler you use |
| 06:45.31 | davidc__ | so neither will help with that kinda thing |
| 06:47.05 | bd2 | yeah, true. but GNU asm manual is somewhat what do not cover =0xXXXX syntax, and other issues. or I'm overlook it |
| 06:48.15 | davidc__ | bd2: to be honest, I don't know then |
| 06:48.23 | davidc__ | bd2: I sorta learned it through osmosis ;) |
| 06:49.22 | bd2 | I hope I'll do it likewise. but when I become ARM-guru, I promise to write humane guide ;-) |
| 06:52.58 | bd2 | iteresting why linux kernel developers use "ldr rN, =" syntax, instead of mov |
| 06:55.24 | davidc__ | bd2: there are only some cases where mov can be used with a constant |
| 06:55.38 | davidc__ | it can only be an 8 bit value + an arbitrary shift |
| 06:55.56 | davidc__ | aka - you could mov r0, #0x000000FF |
| 06:56.06 | davidc__ | but you couldn't do mov r0, #0x000001FF |
| 06:56.17 | davidc__ | simply because the instruction set doesn't allow it ;) |
| 06:56.42 | davidc__ | you can always composite it with somthing like: mov r0, #0x000000FF |
| 06:57.27 | bd2 | yep. got it. Error: invalid constant -- `mov r0,#0x12345678', arm instructions is 4-bytes only |
| 06:57.36 | davidc__ | exactly |
| 06:57.48 | davidc__ | sometimes its more efficient to compose it with a mov + an orr |
| 06:57.59 | davidc__ | sometimes its more efficient to do the = syntax |
| 06:58.08 | davidc__ | depends on your cache + a bunch of factors |
| 06:59.30 | bd2 | great. thanks davidc__ ! |

| 12:55.36 | bd2 | /arm/mach-pxa/generic.c defines uncached memory at virtual address 0xFF000000, and physical address 0x0. When MMU turned on I should use 0x0, and when turned off 0xFF000000, am I right? |
| 12:56.24 | bd2 | ouch. contra. |
| 12:57.13 | bd2 | it's all because Intel Errata says I should read uncached memory at somewhere |
| 12:57.38 | prpplague | there is a difference between cachced and mapped memory |
| 12:58.07 | prpplague | bd2: what is it your are trying to do? |
| 12:59.09 | bd2 | prpplague, make hx4700 voltage regulator working without hangs. |
| 12:59.42 | prpplague | bd2: thats a little more high level than i was looking for, but... |
| 13:00.06 | bd2 | ah. want to paste.lisp.org from intel doc? |
| 13:00.06 | prpplague | bd2: could you explain what issue you are having with cached and non-cached memory? |
| 13:00.46 | prpplague | bd2: hehe, no i need some details about what you are trying to do, without that i wouldn't know what to look at in the doc |
| 13:02.35 | bd2 | heh. I not so cool at VM linux stuff (yet, I hope), take a look at http://paste.lisp.org/display/20568 there are bunch of comments |
| 13:03.08 | bd2 | I mean I can't explain what I'm really trying todo, just whan to make this workaround work ;-) |
| 13:03.41 | prpplague | i see |
| 13:03.48 | prpplague | yea thats pretty detailed asm |
| 13:04.39 | bd2 | in original, they use 0x0A000000 as uncached memory address |
| 13:04.58 | bd2 | except that I've changed nothing |
| 13:05.07 | bd2 | -ed |
| 13:05.21 | prpplague | why did you change it? |
| 13:06.11 | bd2 | because it still hangs with 0x0A000000 (yeah, I know that there may be another reason, but currently I'm trying that). |
| 13:06.38 | bd2 | and 0x0A000000 says nothing to me, as linux sources points to 0xFF000000 and 0x0 |
| 13:08.08 | prpplague | what linux source points to 0xff000000 ? |
| 13:09.46 | bd2 | /arm/mach-pxa/generic.c: /* UNCACHED_PHYS_0 */ ... .virtual = 0xff000000 |
| 13:10.00 | bd2 | .pfn = __phys_to_pfn(0x00000000), |
| 13:10.53 | bd2 | include/asm-arm/arch-pxa/hardware.h also defines UNCACHED_ADDR to 0xff000000 |
| 13:11.20 | bd2 | also hardware.h says that UNCACHED_ADDR used to intel erratas |
| 13:11.31 | prpplague | bd2: just because there is one defined uncached area, doesn't mean there isn't another |
| 13:11.43 | prpplague | bd2: where did you get the original fix from? |
| 13:12.12 | bd2 | from intel site, 28007109.pdf |
| 13:12.34 | bd2 | E28. |
| 13:12.56 | prpplague | bd2: ok so this is an un implemented fix for linux? |
| 13:14.30 | bd2 | I think yes. as there is no hx4700 voltage regulation efforts prior my |
| 13:15.44 | bd2 | if I understood question correctly |
| 13:15.55 | prpplague | ahh |
| 13:16.06 | prpplague | yea well thats gonna be tricky to implement |
| 13:16.28 | prpplague | might want to discuss that on hh.o channel with some of the other folks |
| 13:22.13 | bd2 | unfortunately language barrier will deny even to formulate the question ;-) for now it's easier just keep trying.. |
| 13:33.22 | bd2 | magically changing .aling 5 to .align 7, solved problem without workaround. prpplague, do you have hx4700? |

| 18:42.03 | jbevren | I see |
| 18:42.11 | prpplague | http://anyway.no-ip.org:8080/oci/oci.htm |
| 18:43.34 | prpplague | there are a couple other versions of the board as well on ebay |
| 18:49.47 | prpplague | man some of those guys on ebay think they can get mint prices for those dev boards |
| 18:50.16 | jbevren | no doubt |
| 18:50.19 | jbevren | 700+ |
| 18:51.54 | prpplague | i don't feel well today |
| 18:52.00 | prpplague | i think i'm getting CFS |
| 18:56.24 | *** join/#edev sunrunner20|prom (n=jamesdoe@pool-71-244-25-139.dllstx.fios.verizon.net) |
| 19:01.08 | jbevren | cfs? |
| 19:01.38 | prpplague | chronic fatigue syndrome |
| 19:01.46 | jbevren | ah |
| 19:01.52 | jbevren | need a break? |
| 19:02.52 | prpplague | yea i took one this weekend |
| 19:02.57 | prpplague | doesn't seem to be helping |
| 19:03.06 | prpplague | i actually feel more tired |
| 19:25.18 | joe_bleau | I just went through a "Big Lots" store. Didn't see any interesting hackable stuff. |
| 19:26.46 | prpplague | joe_bleau: hehe, yea big lots generally doesn't have anything |
| 19:26.58 | prpplague | joe_bleau: wonder if they had any kids educational laptops |
| 19:27.24 | joe_bleau | I didn't see any. |
| 19:27.49 | prpplague | ahh |
| 19:27.53 | joe_bleau | But it was on the way back from the Office Depot run (where I picked up the USB hub), so no wasted trip. |
| 19:28.02 | prpplague | ahh gotcha |
| 19:28.19 | joe_bleau | They had some little handheld space invader type games: custom LCD glass, probably ASIC or 6502 micro |
| 19:28.22 | prpplague | joe_bleau: usually i find the neat stuff at toys-r-expensive bargain basket |
| 19:28.26 | joe_bleau | Nothing to get excited about |
| 19:28.30 | prpplague | joe_bleau: yea |
| 19:28.43 | prpplague | joe_bleau: thats the problem i've had with several of the kids laptops |
| 19:28.47 | prpplague | joe_bleau: custom glass |
| 19:29.03 | joe_bleau | Ouch. That would be annoying. |
| 19:29.19 | prpplague | joe_bleau: yea, i've got 3 more units coming in |
| 19:29.29 | prpplague | joe_bleau: hopefully some of these are better |
| 19:29.37 | joe_bleau | What about something targetted to the schools? |
| 19:29.47 | joe_bleau | Thinking of alphasmart, something like that? |
| 19:29.51 | joe_bleau | Qyxie? |
| 19:30.02 | prpplague | not familiar with those |
| 19:30.34 | jbevren | isn't alphasmart the one you typed reports into, and then hooked to the kb port for it to 'type' the report into the pc? |
| 19:31.04 | joe_bleau | They made something with PalmOS |
| 19:31.13 | joe_bleau | http://www.alphasmart.com/products/dana.html |
| 19:31.18 | prpplague | joe_bleau: yea looking at that now |
| 19:31.27 | prpplague | joe_bleau: looks like a possible hack |
| 19:31.43 | prpplague | HOOOOLLLLLYYYY @$#%@#$%@$#% |
| 19:31.57 | prpplague | $429?????????/ |
| 19:32.00 | joe_bleau | Hey, let's keep it clean in here. |
| 19:32.02 | prpplague | are they freakin nuts |
| 19:32.12 | jbevren | the 2000 is $30 on ebay |
| 19:35.01 | prpplague | qyxie looks interesting |
| 19:35.12 | joe_bleau | 8051 based, standard char mode LCD |
| 19:35.32 | joe_bleau | modulated IR, not IrDA |
| 19:35.50 | prpplague | joe_bleau: i'd be gutting it anyway |
| 19:36.09 | prpplague | joe_bleau: whats the lcd size? |
| 19:36.21 | joe_bleau | 20x2 or 40x2, can't recall. |
| 19:38.45 | prpplague | looks to be 4 lines |
| 19:39.06 | prpplague | yea appears to be 40x3 |
| 19:39.08 | prpplague | yea appears to be 40x4 |
| 19:39.34 | prpplague | oh wait that is the 3000 |
| 19:40.17 | prpplague | interesting devices though |
| 19:40.36 | prpplague | yea the 2000 has 40x4 as well |
| 19:41.17 | prpplague | joe_bleau: thanks for the pointer, i'll have a look |
| 19:41.24 | prpplague | joe_bleau: that might be what i need |
| 19:41.41 | prpplague | joe_bleau: you used one before? |
| 19:42.11 | joe_bleau | No, but I know someone that worked on the Qyxie |
| 19:42.37 | prpplague | joe_bleau: oh |
| 19:42.52 | prpplague | joe_bleau: ebay doesn't seem to have any of the qyxie listed |
| 19:43.08 | joe_bleau | I'm not sure it went into production |
| 19:43.28 | prpplague | ahh ok |
| 19:43.56 | joe_bleau | http://www.qyx.com/QYXieFullScreen.html |
| 19:44.09 | joe_bleau | Looks like 40x2 |
| 19:44.22 | jbevren | I agree |
| 19:44.33 | prpplague | yea |
| 19:44.48 | jbevren | the keyboard matrix is easy enough to guess tho :D |
| 19:45.25 | prpplague | jbevren: i wouldn't even guess, just wire up the matrix and they just use a keymap to do correct mapping |
| 19:45.33 | prpplague | s/they/then |
| 19:46.59 | prpplague | hmm, wonder how many batteries it takes |
| 19:47.10 | joe_bleau | I think they were using a rechargeable pack |
| 19:47.29 | prpplague | hmm says 3xAA |
| 19:47.34 | prpplague | :( 4.5 v |
| 19:48.02 | joe_bleau | Oh, where did you see that? |
| 19:48.02 | jbevren | toss three lithium batts in and you have 9v :) |
| 19:48.06 | jbevren | why's 4.5v bad? |
| 19:48.31 | prpplague | jbevren: need atleast 5v for misc stuff like usb and uarts |
| 19:48.46 | joe_bleau | Wait, http://www.qyx.com/Dimensions.html claims 7V |
| 19:49.19 | joe_bleau | Doh. Sorry. |
| 19:49.54 | prpplague | hmm |
| 19:50.16 | prpplague | bummer |
| 19:50.32 | prpplague | would have perfect if it had 4xAA |
| 19:51.17 | prpplague | must be 3.3v lcd stuff |
| 19:51.31 | prpplague | or maybe using a pwm voltage doubler |
| 19:52.15 | joe_bleau | You mean a switched cap voltage doubler? |
| 19:53.28 | prpplague | joe_bleau: hehe, we come from different ends of the EE , not sure if thats the same thing |
| 19:54.07 | prpplague | joe_bleau: http://sprite.student.utwente.nl/~jeroen/projects/ledbl/ |
| 19:54.19 | prpplague | joe_bleau: something like what he did with atmel chip |
| 19:54.49 | joe_bleau | SMPS with a micro to close the loop |
| 19:55.16 | prpplague | what ever you said, hehehe |
| 19:55.42 | joe_bleau | switched cap doubler doesn't need the inductor, but it's only good for low power |
| 19:56.05 | joe_bleau | (The max202/232 series uses a switched cap to generate the RS-232 voltages...that's why those chips require those caps) |
| 19:56.31 | prpplague | ahh gotcha |
| 19:58.15 | prpplague | joe_bleau: Item number: 6055370092 |
| 19:58.24 | prpplague | joe_bleau: thats one of the ones i'm looking at |
| 19:59.01 | prpplague | joe_bleau: has touch screen and grey scale 240x240 lcd |
| 19:59.18 | joe_bleau | For $5, I don't think you can go wrong. |
| 19:59.54 | prpplague | joe_bleau: runs on 4xAA |
| 19:59.58 | prpplague | joe_bleau: so plenty of power |
| 20:00.09 | prpplague | <PROTECTED> |
| 20:00.13 | prpplague | there is another one |
| 20:00.33 | prpplague | little smaller screen and no touch screen |
| 20:01.14 | joe_bleau | I love the pre-printed windows 95 UI motif |
| 20:01.31 | prpplague | hehe yea |
| 20:01.48 | prpplague | <PROTECTED> |
| 20:01.50 | prpplague | and one more |
| 20:01.58 | prpplague | those are the best three i've found |
| 20:02.13 | joe_bleau | Wonder when they'll start using XP style graphics |
| 20:02.21 | prpplague | hehe |
| 20:02.53 | prpplague | joe_bleau: i really really like this one - Item number: 6050384326 |
| 20:02.58 | sunrunner20|prom | mmm |
| 20:03.02 | prpplague | joe_bleau: just can't figure out how to put my stuff in there |
| 20:03.05 | sunrunner20 | windows rolled withapps |
| 20:03.26 | joe_bleau | Modular! |
| 20:03.28 | prpplague | joe_bleau: the center green piece comes out like a GBA |
| 20:04.39 | prpplague | i've got a s3c2410 board i could put in that green one |
| 20:04.43 | prpplague | but it would be hard |
| 20:04.46 | prpplague | lots of work |
| 20:05.14 | prpplague | joe_bleau: i want to make sure that my work can be replicated |
| 20:10.10 | prpplague | http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=244646 |
| 20:10.18 | prpplague | doesn't that look to be a AA package? |
| 20:11.30 | joe_bleau | Can't tell. I have a bunch of pri lithium cells that are AA sized. |
| 20:11.47 | joe_bleau | High impedance, so they don't work well in mini-mag flashlights. |
| 20:11.48 | prpplague | joe_bleau: yea i looked up the specs |
| 20:11.55 | prpplague | joe_bleau: 3.6 in a AA package |
| 20:11.58 | prpplague | hmm |
| 20:13.00 | prpplague | joe_bleau: thats interesting i could get some of those to put in the unit |
| 20:13.44 | prpplague | joe_bleau: 2400mAh |
| 20:13.46 | prpplague | nice |
| 20:13.57 | joe_bleau | Lemma check and see what mine are |
| 20:16.15 | joe_bleau | I've got a bunch of these: http://www.photobattery.com/ls1450_1.pdf |
| 20:16.39 | joe_bleau | And they have the real AA style tip, not the flat top |
| 20:17.04 | prpplague | what do you charge it with? |
| 20:17.37 | joe_bleau | *pri* lithium... |
| 20:18.09 | prpplague | ?? |
| 20:18.24 | joe_bleau | It's a primary lithium cell, not a secondary. |
| 20:18.29 | joe_bleau | It's not rechargeable. |
| 20:18.33 | prpplague | oh |
| 20:18.37 | joe_bleau | Think cheap coin cell for your watch. |
| 20:19.12 | joe_bleau | That Jameco is rechargeable |
| 20:19.18 | prpplague | http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=240303 |
| 20:19.25 | prpplague | thats the one i'm gonna get |
| 20:19.38 | prpplague | just not sure what to use to charge it |
| 20:19.50 | joe_bleau | I'm not sure that was is rechargeable |
| 20:20.12 | prpplague | its listed under rechargable |
| 20:20.14 | joe_bleau | Nope, but it's an upgrade over my SAFT cells. |
| 20:20.19 | joe_bleau | Check the spec sheet. |
| 20:21.15 | prpplague | where do you see a spec sheet? |
| 20:21.32 | joe_bleau | google for "ER14505" http://www.everspring.net/product-socl2-ER14505.htm |
| 20:22.33 | prpplague | hmm |
| 20:22.42 | prpplague | i don't see where it indicates its not rechargeable |
| 20:22.46 | joe_bleau | Jeez, these SAFTs are high dollar. |
| 20:22.59 | joe_bleau | At the top: "ER14505 Lithium Primary Battery" |
| 20:23.26 | prpplague | ahh you have to look for the word primary |
| 20:23.28 | prpplague | ok gotcha |
| 20:23.39 | joe_bleau | Or read the cautions at the bottom: "Do not make the battery short-circuit and do not try to charge it." |
| 20:24.40 | prpplague | hehe |
| 20:27.13 | joe_bleau | Another low-end arm board: http://makezine.com/controller/ |
| 20:27.54 | prpplague | yea just a sam7 though |
| 20:29.29 | joe_bleau | But it'll geneate tons of geek buzz by association with Make |
| 20:29.43 | prpplague | ?? |
| 20:30.35 | joe_bleau | I know a lot of geeks that follow Make. They're not embedded pros, so they'll not be aware of other competing |
| 20:30.42 | joe_bleau | products that may be a better value. |
| 20:33.00 | prpplague | i guess i'm out of the loop |
| 20:33.09 | prpplague | is Make a product line or something?> |
| 20:33.20 | joe_bleau | It's a fairly new magazine. |
| 20:33.30 | joe_bleau | http://makezine.com/magazine/ |
| 20:33.32 | prpplague | ahh |
| 20:33.59 | joe_bleau | CCI for the IT types that are learning to solder? |
| 20:34.30 | prpplague | cci? |
| 20:34.35 | joe_bleau | That's not fair. And some of the projects aren't electronic. |
| 20:34.43 | joe_bleau | Circuit Cellar Ink. You do know that one, right? |
| 20:34.58 | prpplague | yea |
| 20:35.19 | joe_bleau | I just resub's. |
| 20:55.49 | joe_bleau | Oh, yeah! http://geek.scorpiorising.ca/RDH4.html |
