| 05:24.02 | JViz | can an lpc2900 run linux from an sd card? |
| 05:29.19 | JViz | why do all these companies make 0.8mm pitch BGAs when it is impossible to get 3/4mil pcbs made cheaply? |
| 05:29.57 | tsm_ice9 | LPC can run linux from an SD card yeah, but you'll have to write a program to copy the kernel to RAM first probably |
| 05:30.05 | tsm_ice9 | and it'd have to be external RAM most likely |
| 05:30.24 | JViz | ah |
| 05:30.33 | tsm_ice9 | you can't run it straight from the SD card |
| 05:31.12 | JViz | have you ever made a custom arm board? |
| 05:31.36 | alex4nder | hey |
| 05:31.47 | JViz | hi |
| 05:32.55 | alex4nder | JViz: you ever used the LPCs? |
| 05:33.30 | JViz | nope |
| 05:34.33 | alex4nder | ah |
| 05:34.43 | JViz | i'm just looking around for something cheap and easy to accomplish what i want |
| 05:34.57 | alex4nder | do you need something with an LCD, or do you just need linux? |
| 05:35.06 | JViz | both |
| 05:35.10 | JViz | that's basically it |
| 05:35.27 | JViz | something that i can run a gui framework on that can do drag and drop |
| 05:35.49 | JViz | i think both gtk and qt can do that |
| 05:35.55 | JViz | so i need a cpu that can run one of those |
| 05:36.41 | JViz | i figure it will need to have external ram, because images are kind of large chunks of data |
| 05:36.54 | alex4nder | yah, no to mention running Linux |
| 05:37.00 | JViz | yeah |
| 05:37.28 | alex4nder | have you looked at the a91sam9263? |
| 05:37.43 | alex4nder | it's a BGA, but it has the capabilities you want |
| 05:38.23 | JViz | does it come with schematic symbols and pcb footprints? |
| 05:39.07 | JViz | these big chips are a pain in the butt to make symbols for |
| 05:39.54 | JViz | hmm, they're a bit expensive... |
| 05:40.20 | JViz | not horrible, but i could get an i.mx31 for that price |

| 06:01.10 | JViz` | in their results, their skillet worked better than their industrial oven |
| 06:01.21 | JViz` | mainly because they had parts that could melt |

| 06:04.49 | pytey | JViz`: I wouldn't recommend using BGA in a home made design |
| 06:04.58 | pytey | it'll end up as a big ball of fail |
| 06:05.12 | JViz` | why? |
| 06:05.20 | pytey | you need xray to check the balls |
| 06:05.35 | pytey | that you have adequate reflow |
| 06:06.10 | pytey | just some advice, it is up to you of course, but try to avoid BGA |
| 06:06.31 | JViz` | do they put xray machines in the reflow ovens? |
| 06:06.56 | pytey | no, but they xray each PCB after they've been reflowed |
| 06:07.03 | pytey | and discard the failures |
| 06:07.09 | pytey | (or repair them) |
| 06:07.31 | JViz` | yeah, you would just reflow it again, until you kill the board, right? |
| 06:07.37 | pytey | that is part of the inspection process |
| 06:07.42 | pytey | no |
| 06:07.52 | pytey | you'd remove the BGA, reball and do it again |
| 06:07.59 | pytey | pain in the arse |
| 06:08.01 | pytey | big time |
| 06:08.06 | JViz` | i'm not planning on mass producing them in my home |
| 06:08.23 | pytey | just saying, avoid BGA at all costs :P |
| 06:08.27 | JViz` | rgr |
| 06:09.16 | pytey | it could be fun to do a few, then you'll say to yourself "you know what, that was a pain in the arse, next time I'm going to avoid BGA at all costs" |
