Thanks. I've done that on other boards, but somehow had forgotten to do it for the emulator.
When I did it, I saw this message: Error: unrecognized/unsupported processor variant (0x410fc080). After poking around a bit, I figured out that the emulator is running as a Cortex A8 processor, but my kernel was compiled for an ARM 926 CPU. I found that using the 'goldfish_armv7_defconfig' solved the problem. It would be nice to get this little tidbit of information into the online docs somewhere. I guess somewhere along the line, Google decided to switch the emulator from emulating an ARM926 to a Cortex A8, and they have a defconfig to match that. You just need to know to use it instead of the goldfish_defconfig. Thanks again for the tip. -- Tim On Thu, May 3, 2012 at 9:24 PM, Tirtha Ghosh <gtir...@gmail.com> wrote: > I never worked on Android emulator.
