| 01:07.11 | MonMotha | alex4nder: you wouldn't want their driver even if they had one, at least if their code for their "Kinetis" line is any indication |
| 01:07.24 | MonMotha | and I remember their HC08/JM08/9S12 code being pretty bad, too |
| 01:07.29 | MonMotha | it barely works for the demo |
| 01:08.06 | MonMotha | xorrbit: it will heavily depend on lots of factors, but that seems fairly reasonable for a modest system. The bigger question is does it satisfy your needs in this application? |
| 01:08.26 | alex4nder | MonMotha: dude.. I know |
| 01:08.34 | alex4nder | their JM08 shit is SO fucking bad |
| 01:08.54 | alex4nder | I was hoping that with the linaro involvement, they'd get their head screwed on. |
| 01:08.56 | MonMotha | to be fair to Freescale, vendor code -in general- seems pretty horrible |
| 01:09.29 | MonMotha | not that it excuses them, but they're not appreciably worse than many others (but a few others are somewhat better) |
| 01:09.41 | alex4nder | my favorite part is they make the reference board, and put the PMIC on it, and released it, without anything newer than v2.6.35 working. |
| 01:09.54 | MonMotha | part of Freescale's problem is that their hardware is so freaking quirky. It definitely suffers from "design by committees" (note the plural) |
| 01:10.03 | alex4nder | yah |
| 01:10.12 | alex4nder | the imx series seems like the hardware has at least gotten better |
| 01:10.38 | alex4nder | well, I hopeso,.. otherwise the next half decade of product maintenance is going to suck |
| 01:10.39 | MonMotha | I remember people complaining pretty hard about i.MX when it was new. It was one of the first "big" MCUs I'd seen with a full crossbar switch, etc. though |
| 01:11.13 | MonMotha | those are really common now, of course |
| 01:11.31 | MonMotha | you can buy little Cortex-M0s with like 2-3 RAMs and a bazillion simultaneous DMA channels |
| 01:11.50 | MonMotha | crazy that you can get several Gbps internal bandwidth out of like a 60MHz MCU |
| 01:11.56 | alex4nder | the future is now |
| 01:12.18 | MonMotha | some dual core M0+M4 chips are starting to appear, too |
| 01:12.45 | MonMotha | I think NXP had one that has 2 TCMs on the M4, one on the M0, 2 shared SRAMs plus an external bus |
| 01:12.55 | MonMotha | that's 6 DMA'able RAMs |
| 01:13.31 | MonMotha | (and the old-school guys who aren't used to DMA wince at the thought of trying to use one of them) |
| 01:13.51 | alex4nder | yah, who's on first |
| 01:14.00 | alex4nder | it's pretty rad when it works, though |
| 01:16.26 | MonMotha | I've got a little board sitting on my bench right now playing back full CD quality audio off an SD card (SPI mode) using about 20% of the CPU, and I know several parts to be super unoptimized (I also don't care, since it works) |
| 01:16.50 | MonMotha | DMA off the SD card, DMA into the I2S controller, ping-pong double buffer |
| 01:17.20 | alex4nder | yah |
| 01:17.23 | alex4nder | sick |
| 01:17.41 | MonMotha | to be fair, it's a 90MHz CPU. I could just about do that in software...but I'd take the whole CPU to do it. |
| 01:17.52 | alex4nder | I'm working on a board right now, and I would really love some DMAed CAN cores. |
| 01:17.53 | MonMotha | and of course it's doing other things |
| 01:18.00 | MonMotha | I think the CAN on this thing will DMA... |
| 01:18.10 | MonMotha | well, on this thing's big brother |
| 01:18.19 | MonMotha | (not that I recommend them - see above regarding quirkiness) |
| 01:18.35 | MonMotha | though if you need help with one of these things, I offer consulting services :) |
| 01:18.39 | MonMotha | (or you can just buy my code) |
| 01:18.50 | alex4nder | haha, that's what I'm being paid for |
| 01:18.58 | MonMotha | nothing wrong with subbing things out :) |

| 02:13.28 | MonMotha | I actually have a company set up that people contract with, but I'm the only "employee" (and not even officially one) |
| 02:13.41 | MonMotha | I can bring in other resources if needed, though. I have someone who is good with application software |

| 18:25.43 | wmat | landley: am I confused or is there a few typos in that interview? For example, "proposed a new "Bentobox" project to extend toolbox and push the changes upstream to Google". What is "toolbox" in that sentence referring to? |
| 18:26.02 | landley | Toolbox is android's command line utility. |
| 18:26.15 | wmat | ah, that makes sense now |
| 18:26.22 | landley | Their bionic is to libc as toolbox is to busybox. |
| 18:26.38 | wmat | thx |
| 18:27.50 | wmat | the author should have capitalized its first usage |
| 18:36.42 | landley | I poked him. (@codepope on twitter.) |
| 18:37.05 | landley | I went out of my way _not_ to capitalize toybox, since BusyBox has two so I feel the capitalization's taken care of already... |
| 18:44.29 | prpplague | landley: dandy! |
| 18:50.48 | prpplague | landley: posted it on my g+ stuff |
| 18:50.59 | landley | prpplague: woot. :) |
| 18:51.27 | landley | Sigh. I'd probably use G+ if A) it didn't stay logged in and track google stuff, B) they hadn't broken my account so I can't log IN anymore. |
| 18:51.36 | prpplague | wmat: toolbox is basically the core portions of busybox, without the compatibility of most of the syntaxes |
| 18:51.44 | prpplague | wmat: real pain to use |
| 18:51.51 | mnemoc | but BSD :) |
| 18:51.53 | prpplague | landley: doh |
| 18:52.20 | landley | I had a rob at landley dot net account with them forever, and then mirell set up a separate one to wash my email through (a landley.net "hosted" domain), and then they collapsed the two together into a giant train wreck. |
| 18:52.20 | wmat | prpplague: yeah, I just didn't recognize what the author meant. I thought he'd just misspelled Toybox or something. |
| 18:52.35 | landley | prpplague: toolbox is only about 2 dozen commands, several of which don't exist anywhere else, and is crap. |
| 18:52.39 | landley | I looked at the code: it's crap. |
| 18:52.46 | landley | Their ls supports _no_ options. |
| 18:53.01 | landley | Their chmod only understands octal permissions and one file argument. |
| 18:53.03 | landley | That sort of thing. |
| 18:53.27 | landley | It may suck slightly less in ice cream sandwich, but not categorically less. |
| 18:53.36 | landley | Both bionic and toolbox are "enough to run dalvik, and not a line more". |
| 18:53.44 | wmat | damn, it's cold in my geekcave today |
| 18:54.16 | landley | (They're deploying hundreds of millions of broadband-connected yet unadministered touring complete systems. They don't want any more code running outside of the java sandbox than absolutely necessary.) |
