| azonenberg | where'd wolfspraul go lately? havent seen him around | 08:44 |
|---|---|---|
| Fallenou | he's drowning under a large schematic sea | 08:47 |
| Fallenou | I guess :) | 08:47 |
| azonenberg | lol | 08:51 |
| azonenberg | i was going to tell him that i got a new decap setup so i can get some die pics now | 08:51 |
| azonenberg | next time someone sees him send him this http://siliconexposed.blogspot.com/2013/01/new-decap-setup.html | 08:51 |
| kyak | azonenberg: you might as well use memoserv (/quote memoserv help) | 09:28 |
| kyak | and wow, impressive work | 09:28 |
| azonenberg | didnt know there was one here | 09:28 |
| azonenberg | and thanks | 09:28 |
| kyak | azonenberg: correct me if i'm wrong. Decapping of MCU allows not only to break protection, such as read-only switch, but also reproduce the MCU? | 09:42 |
| azonenberg | Depackaging just lets you look at it | 09:43 |
| azonenberg | What you do after that is up to you | 09:43 |
| GitHub112 | [milkymist-ng] sbourdeauducq pushed 7 new commits to master: http://git.io/ZUzhCg | 09:43 |
| GitHub112 | milkymist-ng/master b0503aa Sebastien Bourdeauducq: software/include/base/stdint.h: more definitions | 09:43 |
| GitHub112 | milkymist-ng/master e4144f2 Sebastien Bourdeauducq: software/common.mak: use -target instead of deprecated -ccc-host-triple | 09:43 |
| GitHub112 | milkymist-ng/master c490917 Sebastien Bourdeauducq: software/common.mak: remove -fsigned-char from CFLAGS | 09:43 |
| Action: sb0 recommends active noise cancelling headphones for better nerdage onboard aircraft | 09:44 | |
| azonenberg | kyak: Given enough time, effort, and electron microscope time you could fully clone the chip (ignoring legal issues) | 09:44 |
| azonenberg | But my interest is not in cloning devices, I want to see how they work | 09:44 |
| azonenberg | As well as security analysis | 09:44 |
| kyak | kewl | 09:44 |
| kyak | have you tried to do that with very complicated devices, like modern processors? | 09:45 |
| azonenberg | My group is mostly interested in building a body of public knowledge on how IC reversing works | 09:46 |
| azonenberg | While the fab of small devices is a lot harder than large ones, once you have photos it's no harder to figure out how they work (ignoring scalability issues in the analysis tools for huge netlists, etc) | 09:46 |
| azonenberg | So we mostly stick to >=350nm devices which are possible to study by optical microscopy | 09:47 |
| azonenberg | since SEM is somewhat pricey to get time on and optical scopes are free (I have four in my lab i can use whenever i want) | 09:47 |
| azonenberg | That said, I do want to see a spartan6 naked at some point and the lower levels will need a SEM | 09:47 |
| kyak | ok, i see | 09:48 |
| Fallenou | 10:44 * sb0 recommends active noise cancelling headphones for better nerdage onboard aircraft < yeah, buy Parrot Zik heaphones :D | 09:58 |
| Fallenou | headphones* | 09:58 |
| sb0 | I have Bose Quietcomfort 15 | 10:01 |
| sb0 | works pretty well | 10:01 |
| Fallenou | yeah Bose are quite known for having good audio quality and good noice cancelation | 10:15 |
| bkero | They're quite well known for that. Unfortunately they don't actually make very good products anymore, just coasting on reputation. | 10:19 |
| bkero | Very common for people who know nothing at all about audio to just say "bose makes good stuff, buy bose" | 10:20 |
| wpwrak | noice-canceling headphones are nice. but your ears will still hurt after a while. better get a few drinks and just sleep through the ordeal. | 11:27 |
| wpwrak | azonenberg: you need to integrate this: eching and scanning in one easy device. put in the chip, press a button, out come transistor-level pictures :) | 11:28 |
| kyak | i have a name for that - IC scanner :) | 11:38 |
| larsc | I guess I'm the only one who finds the airplane engine noise comforting | 11:39 |
| kyak | yeah.. at least it means that the engines are still running :) | 11:40 |
| wpwrak | larsc: there are some planes where it's not :) especially tail-engined ones with seats all the way into the hindmost corner. (and of course, no windows back there either) | 11:44 |
| wpwrak | larsc: but i think the real enemy here are human voices. especially those of young humans. | 11:45 |
| larsc | that's why I like the engine noise, it cancels out verything else | 11:46 |
| wpwrak | larsc: hmm, they have to rev very high to drown the shrieking of young humans. | 11:47 |
| wpwrak | larsc: i'm not sure i'd find it very comfortable to hear an engine go like that for very long. in fact, it probably won't :) | 11:48 |
| wpwrak | s/comfortable/comforting/ | 11:48 |
| larsc | azonenberg: over at #homecmos wolfgang is actually creating quite some noise | 14:20 |
| wpwrak | larsc: is he ? checking http://irclog.whitequark.org/homecmos/ doesn't look very noisy | 15:52 |
| larsc | join,part,join,part,join,part | 15:52 |
| larsc | with different ips | 15:52 |
| wpwrak | ah, that kind of noise ;-) | 15:55 |
| Fallenou | mwalle: could you send me your tb_lm32_system as well as your test_mmu_*.elf? | 18:33 |
| Fallenou | I bet my elf files are different, due to my toolchain, I will try to compare the generated assembly :) | 18:34 |
