*Try with these steps * (1) Take the kernel running on your phone. (2) Download the vanila kernel with the same version as above. (3) Do a winmerge/meld (or any other diff-merge tool). These differences (go deep into the source tree mainly in the arch/arm folder if your phone is based on ARM or into the specific processor specific arch code) are *chip driver* of your phone (hardware specific code), the differences will be distributed in 10-15 places. (4) Take *diff *of the 1&2 , this will be the chip driver. (5) Logically attach this* diff* to the kernel of your choice. (6) Build the kernel. (7) Logically fix *each and every build error* encountered while building the kernel.
Do not hesitate to move/replace some header files from phone kernel (mainly from arch/arm folder) to new kernel, as it is, in this process. This is the correct and proven approach Wishes Raja Pavan On Mon, Feb 14, 2011 at 2:06 AM, Aldrin Montana <drinmont...@gmail.com>wrote: > Hi, > > Just to expand on this thread, I managed to successfully boot 2.6.29 > goldfish on an emulator, but I'm curious how to compile a kernel for an > actual device? particularly an HTC G1.
