| 10:11.26 | boris_OmegA | hi there |
| 10:11.50 | boris_OmegA | i have a problem booting my arm based board ( at91sam series) |
| 10:12.16 | boris_OmegA | bootstrap isn't detected nor launched |
| 10:12.57 | boris_OmegA | i think i've erase the rom boot code that check arm vectors to find a bootable media |
| 10:13.10 | boris_OmegA | any idea ? |
| 10:46.15 | MonMotha | boris_OmegA: if that's what you think, then that's probably what happened |
| 10:46.18 | MonMotha | re-install at91boot |
| 10:46.23 | MonMotha | (or whatever you were using |
| 10:46.57 | MonMotha | if it's really not there, you can probably use SAM-BA to do that via USB since lack of that boot code will cause the internal ROM to run the device side of SAM-BA |
| 10:47.31 | boris_OmegA | of course |
| 10:47.36 | boris_OmegA | it's what happens |
| 10:47.44 | boris_OmegA | "RomBoot " at startup |
| 10:48.04 | boris_OmegA | but i don't have the binary file , and don't know where to put it :s |
| 10:48.25 | boris_OmegA | i only have knowledge about bootstrap and u-boot |
| 10:48.40 | boris_OmegA | thank you MonMotha |
| 10:49.07 | MonMotha | well, if you blew away at91boot or whatever was handling the hand-off from the onboard boot ROM to u-boot, you'll need to replace it, and you'll need an image of it to do so |
| 10:49.21 | MonMotha | Atmel has something called "at91boot" that does just that. It's pretty simple |
| 10:49.41 | MonMotha | you can use Atmel's tool called "SAM-BA" to put it on the target device |
| 10:49.58 | MonMotha | I can't point you at an image because it is device specific |
| 10:50.35 | boris_OmegA | ok |
| 10:50.48 | boris_OmegA | it's at91sam9263-ek, for info ^^ |
| 10:51.09 | boris_OmegA | but, with SAM-BA i only can access dataflash and nandflash |
| 10:51.13 | boris_OmegA | no ? |
| 10:51.37 | boris_OmegA | i'll have a look on google to find at91bot |
| 10:51.39 | boris_OmegA | +o |
| 10:57.35 | MonMotha | do you have a rev B chip on your EK? |
| 10:57.53 | MonMotha | if not, you MUST put the bootloader (at least the part called by the ROM) in dataflash |
| 10:58.10 | MonMotha | if you have a rev B, you can boot from dataflash, NAND, or SD card |
| 10:58.42 | *** join/#edev Bluenarf (n=Paul@apollo.paulsnet.org) |
| 10:58.44 | MonMotha | also, there seems to be a slight difference between SPI controllers from rev. A to rev. B, so make sure you get the right at91boot image |
| 10:59.16 | MonMotha | what seems popular is to put at91boot and u-boot into dataflash, then let u-boot load the kernel from NAD |
| 10:59.18 | MonMotha | *NAND |
| 10:59.24 | MonMotha | anyway, I need to get some sleep |
| 10:59.27 | MonMotha | it's almost 6AM |
| 11:00.51 | boris_OmegA | oh :) |
| 11:00.56 | boris_OmegA | good night MonMotha;) |
| 11:01.16 | boris_OmegA | but when you speak about "at91boot" do you mean "at91bootstrap" ? |
| 11:01.31 | boris_OmegA | cause i think i miss the one that launch at91botostrap ... :s |

| 15:24.10 | kergoth | hehe |
| 15:24.10 | kergoth | sheesh |
| 15:27.17 | prpplague | kergoth: quick question, i'm using the standard angstrom gpe image, but i'd like to add a few additional packages, is the best way to do that is add them to my local.conf? |
| 15:30.59 | Crofton|work | prpplague, that is what I do for testing |
| 15:31.14 | prpplague | Crofton|work: what is the best syntax for that? |
| 15:31.47 | prpplague | Crofton|work: i.e. i want to add the devmem2 package |
| 15:32.29 | Crofton|work | bother |
| 15:32.43 | Crofton|work | gpe-image does not have IMAGE_EXTRA_INSTALL |
| 15:33.50 | Crofton|work | look at console-image and look at how ANGSTROM_EXTRA_INSTALL is setup |
| 15:34.00 | Crofton|work | add that construction to gpe-image |
| 15:34.14 | Crofton|work | except call the var IMAGE_EXTRA_INSTALL |
| 15:34.46 | Crofton|work | then put IMAGE_EXTRA_INSTALL = "devmem2" in local.conf |
| 15:35.15 | prpplague | pretends he understood that and gives it a try |
| 15:35.20 | Crofton|work | I'll try and push this |
| 15:35.30 | prpplague | Crofton|work: thanks for the info |
| 15:35.33 | Crofton|work | and change the var to IMAGE_EXTRA_INSTALL |
| 15:35.54 | prpplague | Crofton|work: if you are pushing stuff, fix the devmem2.c url to http://www.lartmaker.nl/lartware/port/devmem2.c |
| 15:36.02 | Crofton|work | hrw hates this var, because it means one mans gpe-image could be different to another means image |
| 15:36.13 | prpplague | Crofton|work: yea |
| 15:36.14 | kergoth | grumbles about a variable being named distro specific in a non distro specific package |
| 15:36.22 | Crofton|work | you may need to remind me again :) |
| 15:36.34 | Crofton|work | there is stupid history |
| 15:36.38 | kergoth | Crofton|work: that's pretty silly. our packages vary oen to the next anyway due to variables that effect how they're built.. i dont see this is much different |
| 15:36.52 | kergoth | heh |
| 15:36.58 | Crofton|work | I'm going to make the change :) |
| 15:37.10 | kergoth | wishes there was a good way to encode package configuration in the outputted binary package name |
| 15:37.34 | prpplague | imho devmem2 and lrzsz should be on every arm base image |
| 15:37.51 | Crofton|work | if hrw starts complaining, you can have that discussion with him :) |
| 15:38.13 | Crofton|work | prpplague, everyone has their pet must have packages :) |

| 15:54.24 | prpplague | Crofton|work: hmm i got the packages to build, but they didn't show up in the image |
| 15:54.37 | kergoth | hmmm.. oreilly has buy 2 books and get the third free, right now |
| 15:55.18 | CosmicPenguin | Thats a good deal |
| 15:55.28 | CosmicPenguin | I should get a new perl book - mine is like 7 years old |

| 15:56.47 | CosmicPenguin | Then again, perldoc.perl.org is always nearby |
| 15:57.04 | kergoth | i'm thinking i should pick up some pocket references, i always did like them for reminding me of syntax |
| 15:58.33 | Crofton | prpplague, bitbake -c clean task-base |
| 15:58.39 | Crofton | then rebuild the image |
| 15:59.37 | prpplague | retries |
| 16:07.29 | prpplague | Crofton: that got it |
| 16:07.41 | prpplague | Crofton: why did i have to do a fresh build on task-base? |
| 16:08.45 | Crofton|work | well, I thin rebuilding the image would have done it |
| 16:09.02 | Crofton|work | but there are some things that get sucked in via task-base |
| 16:09.10 | Crofton|work | so I usually go that route |
| 16:09.29 | Crofton|work | there are changes you make that are not detected by the dependency system |
| 16:09.37 | Crofton|work | like make a change in a package and rebuild |
| 16:09.50 | Crofton|work | unless you bump PR, the image does not get rebuilt |
| 16:10.03 | prpplague | ahh ok |
| 16:10.31 | Crofton|work | when you psuh something, you'll bump PR if the change needs to force image rebuilds |
| 16:10.46 | prpplague | gotcha |

| 18:00.31 | g1powermac_PB | a depth defying 4". . .the news people made it sound like the world was coming to an end. . . |
| 18:02.57 | g1powermac_PB | back in NJ, they wouldn't even close the schools down for 4". . . |
| 18:09.11 | prpplague | hehe |
| 18:09.35 | frikker | g1powermac_PB: where you at? |
| 18:10.01 | prpplague | g1powermac: sounds like that bad storm back in 1992, seems like we had about 2 or 3 feet there at radcliff |
| 18:10.02 | g1powermac_PB | out in state of kentucky |
| 18:10.39 | g1powermac_PB | prpplague: hehe, 2 to 3 feet would prolly kill some people in the really rural areas ;-) |
| 18:10.55 | prpplague | g1powermac_PB: yea it was pretty bad |
| 18:11.39 | g1powermac_PB | we use to get 3 ft storms once every five or so years back in NJ |
| 18:11.54 | g1powermac_PB | the worst was the winter of 1995/96 |
| 18:12.14 | g1powermac_PB | we'd get a foot of snow every week, and then got hit with a 3ft storm |
| 18:12.34 | prpplague | Crofton|work: hey, how much do you know about revC of the beagle? |
| 18:12.50 | g1powermac_PB | I ended up staying in school to almost the 4th of july to make up the snow days from that year ;-) |
| 18:13.06 | prpplague | hehe |
| 18:13.53 | g1powermac_PB | the worst part of it, at least for my parents, is that they wouldn't close the schools down till the roads were absolutely horrible |
| 18:14.41 | g1powermac_PB | so even though it was predicted we'd get a foot of snow, they'd open the schools in the morning only to close them a few hours later after six inches was already on the ground |

| 22:07.36 | prpplague | as far as power savings goes |
| 22:08.14 | CosmicPenguin | I say duty cycle is probably better - turning things off is the path to proper power savings |
| 22:10.37 | joe_bleau | Watch out for aliasing against ambient lighting. |
| 22:13.59 | prpplague | joe_bleau: yea thats what i'm afraid of since this needs to work in lots of different lighting |
| 22:15.09 | MonMotha | I've found that as long as I keep the frequency sufficiently high (several kHz) and don't allow a duty cycle *too* low that aliasing isn't a problem |
| 22:15.57 | MonMotha | you can have the same problems with frequency control, but it would go away at other settings, at least |
| 22:16.25 | MonMotha | I presume by frequency control you mean things like fixed on time, variable off time? |

| 22:17.08 | prpplague | yea i'm running the pwm at 36khz varying the duty cycle, which gives me a good range of voltage from 15.75 to 20.98 |
| 22:18.03 | MonMotha | I wouldn't suspect any problems unless 36kHz just happens to beat with standard electronic fluorescent ballast frequencies (which are usually nice round numbers) |
| 22:18.33 | MonMotha | sounds like your minimum duty cycle is still ~75% |

| 22:29.24 | prpplague | MonMotha: yea anything below 15.75 and the leds wink out |
| 22:29.36 | prpplague | MonMotha: anything over 21 is over voltage of the leds |
| 22:32.09 | MonMotha | ah |
| 22:32.16 | MonMotha | sounds like a fairly long string |
| 22:33.15 | prpplague | 8 leds with constant 20mA |
| 22:34.05 | MonMotha | ah |
| 22:34.15 | MonMotha | are you driving them constant voltage or constant current? |
| 22:34.32 | MonMotha | and how are you generating the power? |
