836334 - Create a Panda image with our own build of Android libraries

Status: RESOLVED WONTFIX

(Testing :: General, defect)

Description

[Geoff Brown [:gbrown]]

We want to provide symbol files - unstripped libraries - for Android system services when invoking ndk-stack. libc.so and libdvm.so are of particular concern; a full set of OS libraries is desirable. We likely cannot do this for the tegras, but should be able to do it for the pandaboards.

:jmaher has already started to generate this build and has at least a functional libc.so replacement, with symbols.

A new Panda image needs to be created, using either the unstripped libraries, or their stripped equivalents (the unstripped libs are only needed on the foopies).

We should be able to build a full Android image that matches what we're currently using, and just store the unstripped binaries somewhere for postmortem work.

I have spent 2 full working days just getting libc.so to build, the rest of the stuff has hundreds of errors and I ran into roadblocks getting anything else built.  This would be a P2 issue for me this quarter due to the time required.  There are a lot of other projects on my plate which I have already promised to do.

I believe I was successful at this at some point in the past, I'll give it a shot. I'm travelling next week, so it won't be until the week after that.

I could never get the linaro repos to re-sync here. I'm told that dminor got this working, so perhaps this is FIXED?

I never got further than rebuilding a few libraries for 2.3.5, but I can take this on as a background task.

Comment 6

[Geoff Brown [:gbrown]]

I had a good experience with building the 4.2.2_r1 AOSP, full_panda-eng on Ubuntu 12.04. I generated debug symbols and .img files just fine. However, instructions at device/ti/panda/README say to use fastboot to transfer the .img files to a Panda -- those instructions did not work for me or for :dminor and I have no idea how to transfer the .img files to sdcard otherwise.

You should be able to "make boottarball userdatatarball systemtarball", and then use mcote's script to write those to a pre-formatted SD card (I think the script takes care of the "preformatted" part):

You may have to tweak things a bit since it looks for B2G images, but they're the same thing.

That's great news - thanks! I hope to find time to get back to this soon.

Comment 9

[Dan Minor [:dminor]]

Unassigning from me as I'm not actively working on this and it sounds like gbrown is making good progress.

We are using Pandaboards less now -- no point in putting more effort into this.
