HI ALL:
    I'm trying to bring android up at my MIPS hardware platform,
while the first problem i encountered is app_process(zygote) is crashed.
The source code is pulled from mipsandroid.org
    My hardware has pretty limited memory, only 16M SDRAM,
is it enough to bring up essential android system?

Dennis

Hi Dennis.

I have android running on a MIPS based TV system.
That system has 128MB of ram available and that is
almost eaten up when running Android and Linux.
To get it to work in just 16MB would be quiet some
task.

Hi Hedwin Koning:
   Thanks for your sharing

   Actually it's 32Mbytes, my fault~
   Here I'm a little bit clueless about the problem.
Seems that libsgl.so triggered the exception, but I can't find the offended instruction
according to the value of PC, since libsgl is dynamically loaded.
   Hope people can shed some lights on me, any idea or suggestion is welcome!

Hi All,

I´m getting the same problem in a MIPS board with the same source code. Anyway when I try to launch zygote manually I get a linker error, so I think I have a compilation error.

bionic/linker/linker.c:883| ERROR: [ 1273 - failed to extend segment from 'libc.so' @ 0x7ef69000 (0x0000a9c0) ]

Do you have the same problem? I´m trying to compile for mips32r2.

Not sure whether we have the same problem,
But can you use logcat to dump full debug info?

Seems that you even can't run /system/bin/sh
but here, at least in my system is working (may fail sometimes)

Btw, How much memory do you have?
where is your mips code pull from?

Hi Dennis,

I have the same toolchain. My board have 256MB of RAM. I got the sources doing:

repo init -u git://public.mipsandroid.com/platform/manifest.git -b mips-cupcake

and compiling it for mips32r2. How do you did it?
