| 00:48.50 | prpplague | kergoth: you tim riker still has the old #elinux logs and #tuxscreen logs available |
| 00:49.12 | prpplague | kergoth: lots of interesting comments from you and mallum for historical interest |
| 00:49.39 | kergoth | yeah, i pulled down some of that a while back to track down the origins of OE/openzaurus to put together a timeline :) |
| 00:49.42 | kergoth | cool stuff |
| 00:50.20 | prpplague | kergoth: beth asked me to track down some stuff for her at the last ELCE |
| 00:50.21 | kergoth | I really wasn't very patient back then :) |
| 00:50.26 | prpplague | :P |
| 00:50.26 | kergoth | ah, cool |
| 00:50.40 | prpplague | we were all young and full of piss and vinager |
| 00:51.16 | prpplague | every meeting i have with TI and they talk about OE/Yocto i like to let them know that you worked for TI once, hehe |
| 00:52.05 | prpplague | kergoth: you ever attend any of the conferences? |
| 00:52.12 | *** join/#edev aep (~aep@libqxt/developer/aep) |
| 00:52.15 | prpplague | doesn;t think he's seen kergoth at any |
| 00:52.49 | kergoth | I was at ELC last year or the year before, that's about it. Need to fix that |
| 00:53.11 | prpplague | kergoth: guess in the haste of things we didn't sync up |
| 00:53.22 | prpplague | kergoth: maybe next time |
| 00:53.40 | aep | heya, does anyone know a minimal chip that runs linux without any external components such as ram or nand? kindof like an avr but with arm. |
| 00:54.32 | prpplague | aep: most of the "all in one" arm devices are without mmu, and limited ram/storage |
| 00:54.41 | clever | aep: bcm2835 is the first that comes to mind for me, but good luck getting a supply of unmounted chips |
| 00:55.04 | prpplague | aep: why the requirement? |
| 00:55.04 | clever | oh, and it lacks flash, you would still need nand or an sd card |
| 00:55.16 | aep | prpplague: because ram interfacing is hard |
| 00:55.30 | prpplague | aep: hehe |
| 00:55.36 | SpeedEvil | aep: there are some microcontrollers which will sort-of-do this. |
| 00:55.37 | clever | bcm2835 ram is simple, just stack the ram chip directly ontop of the cpu chip |
| 00:55.41 | SpeedEvil | If you're willing to say uclinux = linux |
| 00:55.45 | prpplague | aep: what you want is called PoP - Package on Package |
| 00:55.59 | clever | thats exactly what bcm2835/raspberrypi uses |
| 00:56.05 | prpplague | aep: there are a wide ranger of ARM based SoC's that have stacked ram/flash |
| 00:56.09 | SpeedEvil | Or go and look at http://b3ta.com/challenge/lostcons/ |
| 00:56.10 | SpeedEvil | err |
| 00:56.21 | SpeedEvil | https://www.olimex.com/Products/OLinuXino/ |
| 00:56.26 | prpplague | aep: including devices such as the DM3730 used on the beagleboard and beagleboard-xm products |
| 00:56.27 | SpeedEvil | The imx233 ones aren't bad at all |
| 00:56.57 | SpeedEvil | It's something like tqfp100 |
| 00:57.22 | SpeedEvil | But yes, actual all-in-one linux would be interesting. There are sort-of-cheats. |
| 00:58.02 | SpeedEvil | http://shop.8devices.com/carambola - for example. |
| 00:58.07 | SpeedEvil | Solder in modules. |
| 00:58.23 | prpplague | kergoth: we need to sync up about a new beaglebone black compatible design we are doing |
| 00:58.26 | aep | oh neat |
| 00:58.36 | prpplague | kergoth: code named "Blue Steel" for industrial uses |
| 00:58.50 | prpplague | kergoth: i'd like to get a solid MG SDK for it |
| 00:58.59 | prpplague | kergoth: with a joint press release |
| 01:09.38 | SpeedEvil | prpplague: Interesting. Conformal coated, more protection on the IO sort of thing? |
| 01:12.29 | prpplague | SpeedEvil: industrial temp rated components |
| 01:12.36 | prpplague | SpeedEvil: no OEM restrictions |
| 01:12.52 | SpeedEvil | Ah. |
| 01:13.39 | SpeedEvil | I was thinking of the guy that PMd me asking how to clean VFD boards with grease congealed on them from a food processing plant. |
| 01:17.51 | prpplague | hhe |
| 01:17.52 | prpplague | hehe |
| 01:57.25 | MonMotha | aep: be aware that package-on-package is difficult even for many "high tech" CMs to assemble |
| 01:57.41 | MonMotha | definitely not something to do with a toaster oven (though it's probably possible) |
| 01:58.23 | aep | nah, i'll stick to a cortex M4 for now until they make chips that i can handle :/ |
| 01:59.36 | MonMotha | aep: FWIW, if you follow the JEDEC SSTL layout guidelines, DDR RAM interfaces usually "just work" |
| 02:00.04 | MonMotha | though the guidelines are somewhat complex, and it really helps to have a layout package that will let you set all the impedance rules up and do interactive length tuning |
| 02:00.29 | aep | i have no idea what you just said, therefor i conclude it isnt for me :P |
| 02:01.17 | SpeedEvil | I looked at a TI howto - it seemed actually doable in toaster oven - with proper control. |

| 02:01.58 | SpeedEvil | align, and place on a carrier, reflow POP on, then reflow the main board using that as a component. |
| 02:02.15 | SpeedEvil | I couldn't find POP memory, or I might have tried upgrading my phone. |
| 02:02.24 | SpeedEvil | ^compatible |
| 02:02.36 | MonMotha | SpeedEvil: you can sample some of that from Micron if you happen to know a local rep |
| 02:02.50 | SpeedEvil | MonMotha: alas no. |
| 02:03.15 | SpeedEvil | Most of the time, my volume is 0/year :) |
| 02:04.05 | MonMotha | SpeedEvil: people give me samples on the grounds that I'm often spec'ing stuff for production designs, so even if MY volume is 0/yr, the application volume could be well higher |
| 02:04.11 | MonMotha | they do usually want to know anticipated application volume, though |
| 02:05.37 | SpeedEvil | MonMotha: yeah - when the application volume is also 0/year :) |
| 02:06.00 | SpeedEvil | I was kinda tempted to try making a teeny microwave oven with the 150W 2.4GHz FETs NXP was offering me |
