| 15:50.09 | mnemoc | i'm anxius to watch them |

| 21:48.00 | roxfan | derRichard: a hex viewer/editor, ida pro for disassembly and python for scripting |
| 21:49.32 | derRichard | roxfan: and much knowledge on embedded systems? ;) |
| 21:49.46 | roxfan | some |
| 21:50.18 | roxfan | you don't really need to know much to recognize gzip headers |
| 21:50.55 | derRichard | yeah. but why does "file" not recognize the firmwareimage as gzipped file? |
| 21:51.15 | roxfan | because gzipped data is further in the file |
| 21:51.24 | derRichard | ahhh |
| 21:51.26 | roxfan | the beginning is the updater program |
| 21:52.03 | derRichard | the updater program is an arm elf binary? |
| 21:52.24 | roxfan | no |
| 21:52.32 | roxfan | just raw arm code |
| 21:53.08 | derRichard | raw arm code means arm asm code? |
| 21:53.34 | roxfan | it means it doesn't have any headers like elf |
| 21:53.44 | derRichard | okay |
| 21:56.13 | roxfan | you can try objdump -D -b binary -m arm |
| 21:57.24 | derRichard | thx |
| 22:00.43 | derRichard | does ida pro run on linux? i've never used it |
| 22:01.33 | *** join/#elinux likewhoa (~likewhoa@ool-45717734.dyn.optonline.net) |
| 22:03.14 | roxfan | it does, although text version only |
| 22:03.27 | roxfan | there's a gui version in the works |
| 22:05.01 | derRichard | i'm asking because the demo download link points only to an exe file |
| 22:05.16 | roxfan | demo and freeware ver are windows only |
| 22:05.28 | roxfan | but i hear they run fine in wine |
| 22:05.44 | derRichard | nice :) |
| 22:06.00 | roxfan | here's how the beginning of the loader looks (after i worked on it a bit): http://pastebin.ca/1863963 |
| 22:08.22 | derRichard | the firmware image contains a loader program and a payload, right? the loader seems to do a crc check on the payload. |
| 22:08.40 | roxfan | yes |
