| 00:04.48 | Laurenceb | what bank will the arm boot to? 0 ? |
| 00:11.40 | roxfan | i don't think arm has any banks |
| 00:12.18 | roxfan | execution after reset starts at offset 0 in address space |
| 00:13.48 | Laurenceb | right |
| 00:14.09 | Laurenceb | hmm I think all the openocd options confuced me |
| 00:14.09 | Laurenceb | openocd need a flash bank, so I guess thats 0 |
| 00:14.19 | Laurenceb | however flashing with a hex file wont work |
| 00:14.37 | Laurenceb | even if I set the offset as 0x00000000 |
| 00:15.26 | roxfan | did you specify 'hex' in the command? |
| 00:15.30 | Laurenceb | yes |
| 00:15.39 | Laurenceb | guess I could use a bin |
| 00:15.49 | Laurenceb | but I dont have the toolchain setup yet |
| 00:16.02 | Laurenceb | I have a usb mouse demo from olimex I want to try |
| 00:16.07 | Laurenceb | and its a hex file |
| 00:16.35 | roxfan | well, it shouldn't matter i guess... |
| 00:17.00 | Laurenceb | intel hex is 12 bit address mode |
| 00:17.07 | Laurenceb | *16 |
| 00:17.23 | Laurenceb | isnt it? |
| 00:18.11 | Laurenceb | so how can you use if for a 32 bit device |
| 00:18.28 | roxfan | there are extensions for 32-bit afaik |
| 00:18.58 | roxfan | e.g. first a block offset specified, then all bytes for this block |
| 00:19.03 | roxfan | or something like that |
| 00:19.15 | Laurenceb | right |
| 00:19.35 | Laurenceb | maybe thats what it means by offset breaks required alignment |
| 00:20.23 | Laurenceb | oh well I'll try an compile bin files |

| 19:55.57 | roxfan | unless it was supposed to be "Segment kernel"? |
| 19:56.33 | _new_Dev_ | yessegment kernel is the last message shown |
| 19:56.56 | roxfan | hm |
| 19:56.58 | florian | but the pc is inside busybox |
