| 17:26.35 | pat123 | I added a module to the KBuild file, but when enable in menuconfig it doesn't compile the module |
| 17:27.08 | prpplague | pat123: need a little more information |
| 17:27.16 | pat123 | I was wondering if you can point me in the right direction |
| 17:27.21 | prpplague | pat123: are you building a linux kernel? |
| 17:27.32 | pat123 | yes |
| 17:27.50 | prpplague | pat123: are you building the module inside the kernel tree? |
| 17:27.58 | pat123 | yes |
| 17:28.30 | prpplague | pat123: then check to make sure you have added the correct object file listings in the Makefile for that subsection |
| 17:29.37 | pat123 | this is my make file |
| 17:29.42 | pat123 | ARCH := arm |
| 17:29.42 | pat123 | CROSS_COMPILE := /home/pat/hammer/buildroot/build_arm/staging_dir/usr/bin/arm-linux- |

| 17:38.51 | ds2 | oh |
| 17:39.23 | prpplague | pat123: ok, so you are trying to move the hammer ledblink module forward to 2.6.29? |
| 17:39.32 | ds2 | trying to figure out if the new ones are a totally seperate thing or a true decendant of the 24xx stuff |
| 17:39.34 | pat123 | yes |
| 17:40.01 | prpplague | pat123: yea that isn't done inside the kernel tree |
| 17:40.03 | ds2 | pat123: do you have a reference to that directory in the parent make file? |
| 17:40.10 | prpplague | pat123: that is considered outside the kernel tre |
| 17:40.19 | ds2 | nevermind |
| 17:40.55 | pat123 | ds2 you mean like in the Kbuild |

| 17:42.11 | pat123 | ok |
| 17:42.35 | ds2 | pat123: no, I thought you were doing it from the kernel tree... outside is done differently |
| 17:42.51 | pat123 | oic |
| 17:43.11 | pat123 | I wanted to make it in the kernel tree |
| 17:43.43 | prpplague | pat123: why? |
| 17:44.21 | prpplague | pat123: it serves no real purpose other than as a demo app |
| 17:44.33 | pat123 | oic |
| 17:45.12 | pat123 | so outside the kernel and then load it on to the target should fine? |
| 17:45.17 | prpplague | pat123: yep |
| 17:46.51 | prpplague | pat123: you should need to change anything with the example Makefile that comes with the sources, other than providing a full path to your kernel source directory |
| 17:46.56 | pat123 | In what directory is appropriate to put the ledblink.ko on the target |
| 17:47.00 | prpplague | s/should/shouldn't |
| 17:47.41 | pat123 | ? |
| 17:47.47 | prpplague | pat123: you can put it anywhere, but if you plan to have it used on regular basis, add it to the /lib/modules/2.6.29.4/kernel/drivers director |
| 17:48.01 | prpplague | pat123: you _should not _ need to change anything with the example Makefile that comes with the sources, other than providing a full path to your kernel source directory |
| 17:49.19 | pat123 | prpplague and ds2 I appreciate your help |
| 17:49.44 | prpplague | pat123: np, if oyu need any help with the hammer , please give me a shout |

| 17:52.28 | pat123 | I was hoping to somehow using a web broswer to turn on and off the led |
| 17:53.35 | ds2 | pat123: have you looked at the ESC slides for the Beagle? they had a lab exercise to do that and the only change you should need to do is to change the code to use the LED names on the Hammer |
| 17:53.58 | pat123 | no haven't |

| 18:18.09 | prpplague | http://www.elinux.org/Hammer_LED_Driver |

| 19:13.50 | pat123 | how to do it? |
| 19:15.09 | pat123 | the Makefile in the linux-2.6.29.4 directory |

| 19:37.13 | prpplague | pat123: just grab a fresh copy of the makefile from your kernel source tarball |
