| 17:28.12 | grummund | only thing is the binary image size is ~512MB, but it does work! ;-P |
| 17:28.19 | *** join/#edev devilsadvocate (~devilsadv@202.3.77.11) |
| 17:34.14 | calculus | 512MB for blinking lights? |
| 17:52.46 | grummund | yeah :p |
| 17:52.55 | grummund | it is something of a victory to have a flashing LED though :) |
| 17:58.37 | grummund | gcc doesn't seem to want to create me a map file so i can see where the 500MB is being used... |
| 17:58.40 | grummund | arm-elf-ld: unrecognized option '-Wl,-Map=main.map' |
| 17:59.57 | grummund | nvm. |
| 18:03.02 | grummund | ok, 512MB is 0x20000000, which is suspiciously the RAM start address is it not? |

| 21:05.33 | prpplague | ahh |
| 21:17.01 | grummund | aha. reduced the binary image size from ~512M to ~5k with arm-elf-objcopy --only-section=.text |
| 21:17.18 | grummund | and the LED still flashes! \o/ |
| 21:17.39 | prpplague | 512M to 5k? |
| 21:17.56 | grummund | yep |
| 21:18.05 | prpplague | 512megabyte? |
| 21:18.21 | grummund | yes :-P |
| 21:18.30 | prpplague | grummund: uh something is wrong there |
| 21:18.36 | grummund | slight overkill for a blink i thought :-P |
| 21:18.43 | grummund | *blinky |
| 21:19.05 | prpplague | grummund: i've been coding under linux for over 10 years and i have never seen a object file 512MB |
| 21:19.33 | prpplague | grummund: what the heck are you doing? |
| 21:19.35 | grummund | there's a first time for everything |
| 21:20.02 | prpplague | grummund: what code is this? |
| 21:21.33 | dfarnsworth | has seen the linker run out of memory with an object file exceeding 4GB. :) |
| 21:21.42 | dfarnsworth | in my case, it was 4GB of 0xff |
| 21:21.54 | grummund | prpplague: just trying to make an LED flash :-) |
| 21:22.01 | dfarnsworth | so I can believe 512MB |
| 21:22.29 | grummund | well the micro only has 128KB of flash, hehe. |
| 21:22.39 | grummund | but still it worked |
| 21:24.39 | prpplague | grummund: i assume you are doing it in C, if so can you send me a copy of your code? i'd love to see what is going on there |
| 21:25.26 | prpplague | dfarnsworth: seriously? |
| 21:25.30 | prpplague | dfarnsworth: never seen that before |
| 21:25.35 | grummund | prpplague: do you work with ARM Cortex ? |
| 21:25.47 | prpplague | *cough* yea |
| 21:25.54 | grummund | prpplague: this is the board - http://www.sparkfun.com/commerce/product_info.php?products_id=8559 |
| 21:26.18 | prpplague | grummund: love to see your code |
| 21:26.29 | grummund | it's Olimex code |
| 21:26.41 | prpplague | grummund: you can email it to me or if it is small, you can just pastebin it |
| 21:26.44 | grummund | yeah |
| 21:26.53 | grummund | patience is a virtue :-P |
| 21:27.03 | prpplague | dave123rad@yahoo.com |
| 21:27.14 | dfarnsworth | yeah, was building uboot at a high offset. instead of starting at the address of the generated code, the linker was filling with 0xff. I'm sure it was a linker config problem |
| 21:27.43 | grummund | prpplague: http://olimex.com/dev/soft/arm/OpenOCD-projects100.zip |
| 21:28.19 | dfarnsworth | actually, I now remember that the linker exceeded 4GB mem usage, I don't remember how big the (partial) generated obj file was, but it was big |
| 21:28.48 | grummund | prpplague: the project directory is stm_h103 |
| 21:28.49 | prpplague | grummund: which item |
| 21:32.29 | prpplague | grummund: interesting |
| 21:32.45 | prpplague | grummund: my object file was just 89K |
| 21:32.55 | grummund | main.bin ? |
| 21:41.37 | prpplague | main.out is 89k and main.bin is 5k |
| 21:42.07 | grummund | what command do you use to generate main.bin? |
| 21:42.30 | prpplague | grummund: i just ran your makefile |
| 21:42.45 | prpplague | grummund: what toolchain are you using? |
| 21:43.17 | grummund | Yagarto build of arm-gcc for Windows |
| 21:44.01 | prpplague | OH |
| 21:44.07 | prpplague | no wonder |

| 21:44.15 | prpplague | grummund: you left that fact out |
