How did you built kernel, means by make all, or just make module_prepare & make madules ?I found this query on linux-kernel.

Unfortunately, Motorola did not post the kernel configuration they used (https://opensource.motorola.com/sf/sfmain/do/viewProject/projects.droid - I am running 2.2.1). They also did not configure the kernel to dump it at /proc/config.gz. I have the exact source code used to build both the kernel, and the wireless kernel module used. But again, I do not have the exact kernel configuration. Therefore, I do not want to replace the kernel on the phone (in fear of misconfiguration causing boot errors), I simply want to rebuild the wireless module and get it to work with the kernel already on the phone. I've tried getting help from the android community, however their kernel mailing list only gets about 3 messages a day and posts are moderated and lag behind something like 4 days. So, I'm hoping for a little bit of help here on the linux end of things from the linux community. I've ballparked the configuration using an older configuration file posted on another forum, and was able to successfully build my own kernel (albeit I do not use it), and then also build the wireless module successfully. Please check if after build kernel (make all) there is a file Module.symvers in /your_path_to_src_kernel/ There is many disagrees about version of symbol which looks like sources you uesed to build module wasn't for this particular kernel.When I try to load the module on the phone, I get a pretty long list of undefined symbols: http://pastebin.com/re5mRj4E Could you type and paste output of: modinfo tiwlan_drv and modinfo some_other_module_working_on_your_phone -- regards Andrzej Kardas http://www.linux.mynotes.pl |
