but there has to be a version of kexec for android-modified kernels or atleast ARM-linux kernels. On Jan 5, 7:58 am, "Arun K. Singh" wrote: >   > > On Wed, Jan 5, 2011 at 10:01 AM, Chris Stratton wrote: > > On Jan 4, 9:06 pm, Srikant wrote: > > > I agree with you, if

[android-kernel] Re: booting another linux kernel from a running android system

I agree with you, if the requirement is porting to a new h/w platform. But the requirement here is to just porting to a new Linux Kernel version, hence it may not be required to do assembly level debugging. On Jan 4, 3:55 pm, Chris Stratton wrote: > > Instead of this, you can enable Kernel Low L

thanks. if you can share more of your work done, it will be helpful (and save time also) On Dec 31, 8:04 am, Chris Stratton wrote: > I should be possible to set up, but I didn't get it to work in the > brief time I spent trying.  And it's likely going to require running a > patched kernel to star

[android-kernel] Re: booting another linux kernel from a running android system

I should be possible to set up, but I didn't get it to work in the brief time I spent trying. And it's likely going to require running a patched kernel to start. If you want to work on it, I'd highly recommend first getting a working serial output for kernel messages, both hardware wise on your d
