| 00:00.26 | SpeedEvil | I need to get a toolchain setup. |
| 00:01.11 | SpeedEvil | I want to sort out a kernel with encryption and a sensible terminal. |
| 00:01.54 | SpeedEvil | And my barcode 'stuff/diet' tracker thingy |
| 00:10.09 | madsy | What is actually hidden/restricted on the N900, if any? |
| 00:10.27 | madsy | I assume the phone/GSM stuff is decoupled from the rest. |
| 00:10.39 | SpeedEvil | yes |
| 00:10.45 | SpeedEvil | There are several levels. |
| 00:10.51 | SpeedEvil | First you have the closed cores. |
| 00:10.53 | *** part/#edev Omegamoon (n=egoe@demolitionman.xs4all.nl) |
| 00:11.05 | madsy | You don't want consumers to hack that and potentially damage the network. |
| 00:11.15 | SpeedEvil | bluetooth, wifi, gsm are all closed to various degrees and you only talk to them over normal interfaces. |
| 00:11.29 | SpeedEvil | Then you have the kernel - which is all! open. |
| 00:11.41 | SpeedEvil | Then you have the userside drivers, some of which are closed. |
| 00:12.02 | SpeedEvil | 3d, battery daemon, and some of the UI stuff. |
| 00:12.13 | SpeedEvil | much of the rest is open. |
| 00:12.42 | SpeedEvil | It is much the same as many laptops. |
| 00:12.51 | SpeedEvil | Which require non-free components to work. |

| 00:13.20 | madsy | But you can access all the peripherals via standard APIs, right? |
| 00:13.39 | SpeedEvil | Not completely - the battery UI isn't standard. |
| 00:14.04 | SpeedEvil | If you mean can you write your own programs - then absolutely yes. |
| 00:14.06 | madsy | I can live without access to the GSM stuff, but wifi, audio and OpenGL ES should be possible to use in user applications. |
| 00:14.11 | madsy | Great. |
| 00:14.15 | SpeedEvil | I'm currently working out how to put GCC on it. |
| 00:14.29 | madsy | *on* it? You want it to host a toolchain? |
| 00:14.46 | SpeedEvil | It's a 600MHz processor. |
| 00:14.51 | SpeedEvil | Admittedly, not a fast one. |
| 00:14.55 | madsy | You really see yourself writing code on that tiny keyboard? |
| 00:14.57 | SpeedEvil | But it's quite adequate for much. |
| 00:14.58 | madsy | :-D |
| 00:15.13 | SpeedEvil | I have spent a couple of hours playing nethack on it. |
| 00:15.21 | madsy | I'll hack up a cross-toolchain when I get mine. |
| 00:15.23 | SpeedEvil | This may merely be an indication of insanity though. |
| 00:15.54 | SpeedEvil | the keyboard is _really_ surprisingly not that bad. |
| 00:16.05 | SpeedEvil | I think I'm up to ~25wpm or so on it. |
| 00:16.20 | madsy | nice |
| 00:16.59 | madsy | Perhaps I'll extend my emulator to handle Cortex instructions. |
| 00:17.36 | SpeedEvil | What I really want to do is to open it up and solder stuff to it. |
| 00:17.38 | SpeedEvil | :) |
| 00:17.56 | SpeedEvil | A I2C gyro/magnetometer in parallel with the existing accellerometer would be sweet. |
| 00:18.21 | madsy | If you put more stuff on the unit, it'll explode. |
| 00:18.31 | madsy | Or eat one lithium battery per day :-p |
| 00:18.41 | madsy | Not discharge, but literally 'eat' it. |
| 00:18.51 | SpeedEvil | gyro/mag is _lots_ cheaper than GPS |
| 00:20.29 | madsy | Meh.. I wish more hardware nuts with spare time were around. I need more eyeballs on my emulator :-\ |
| 00:20.57 | SpeedEvil | I have most of my time taken up with unfun stuff. |
| 00:21.08 | madsy | Yeah, that's how it usually is. |

| 00:21.15 | SpeedEvil | currently insulating house |
| 00:21.39 | SpeedEvil | Emulator for? |
| 00:22.48 | madsy | ARM920TDMI for now. No 'real' peripherals yet. |
| 00:22.53 | SpeedEvil | ah |
| 00:23.23 | madsy | But it started as a GP2X emulator. Nobel goal, but I'm not a hardware guy. And the needed documentation is written in Engrish. |
| 00:23.45 | madsy | s/novel/bold |
| 00:24.08 | SpeedEvil | Not your native language? |
| 00:24.29 | madsy | Engrish = bad Japanese-English. |
| 00:25.03 | madsy | That in addition to me being pretty incompetent when it comes to understanding pinouts, timing tables, etc |
| 00:26.36 | madsy | Here's the first actual application I ran it with: http://www.mechcore.net/images/gp2xemu/gp2xemu0.png |
| 00:27.00 | madsy | I added a dummy framebuffer one could blit to. |
| 00:27.24 | SpeedEvil | ah - misread |

| 00:28.15 | SpeedEvil | neat. |
| 00:28.21 | SpeedEvil | my last emu was a z80. |
| 00:28.23 | SpeedEvil | :) |
| 00:28.38 | SpeedEvil | and never really worked |
| 00:29.54 | madsy | Mine works, but is too slow to be of any use yet. |
| 00:30.22 | madsy | It's more like an interpreter than a JIT. It's written in straight C. |
| 00:32.43 | solar | woot for no JIT. You remain portable |
| 00:33.51 | SpeedEvil | There are other ways to portability. |
| 00:33.57 | SpeedEvil | JIT to java bytecode. :) |
| 00:34.28 | Mirell | It's a long way, to portability...to the sweetest byte I know... |
| 00:34.49 | solar | Only problem with that is it seems the java interps still need a RWE segment of memory |
