| 00:37.21 | BabelO | Kevin2: yes, if you look at i2c-omap.c it is +4 |
| 00:37.44 | BabelO | why it is strange for you ? |

| 00:42.17 | BabelO | register are here and all are +4, but according to asm file i ve +2 with a strange register in middle |
| 00:46.46 | Kevin2 | Hrmm. How did you disassemble this? Some of the stuff looks odd - LDR R5, =0xB80B3802 - looks like it would throw an alignment fault. |
| 00:48.19 | BabelO | Ah Ah you point me on a bug ? i disassemble with IDA and just take interesting part of code |
| 00:48.29 | BabelO | why an alignement fault ? |
| 00:49.19 | Kevin2 | You're only supposed to do 4byte accesses on a 4-byte aligned address. |
| 00:51.01 | BabelO | yes, agree with you i just thinking that it was a compiler optim, using LDR one time instead of two successive retrieve |

| 01:00.19 | Kevin2 | BabelO: I don't know, but it seems odd to me. You may want to confirm the asm output by just running cegcc's objdump on the dll. |
| 01:00.57 | BabelO | Kevin2: yes maybe they use LDR R2, =0xB80B3812 or LDRH R2,[3] with R3 correctly filled |
| 01:01.21 | BabelO | ok i ll try that tomorrow |
| 01:01.32 | BabelO | ah , maybe it is just a fault from testwm5.exe |
| 01:02.52 | Kevin2 | BabelO: Could be. But I doubt testwm5 would show something mostly correct.. |
| 01:03.23 | Kevin2 | There is no asm statement "LDR R2, =0xB80B3812" -- you can only load a value from a memory location - so IDL must be trying to make it look pretty for you.. |
| 01:04.16 | BabelO | ah ok, i ask cr2 about LDRH this afternoon because i just see LDR and STR in ARM asm code documentation |
| 01:06.50 | BabelO | Kevin2: good night and thanks for your help, i will try to continu compare kernel code to this dll and adjust |
| 01:07.04 | Kevin2 | Ok. Good night. |
| 01:08.07 | BabelO | just one more thing, what is cegcc command line to disassemble ? |
| 01:09.35 | Kevin2 | I use -- /opt/mingw32ce/bin/arm-wince-mingw32ce-objdump -d foo.dll |
