ARM support

An brief search points to the Error: caught unhandled signal 4 meaning a SIGILL which states that some form of illegal or privileged instruction is being called which is being rejected. Hope that helps narrow the issue down.

Below is the system information from the error log as well.

After some more searching, I have narrowed down that the crashing is due to the call:TurboActivateNative.INSTANCE.PDetsFromPath(location);

Hopefully that helps. Thanks for any insight into the issue!

Just to make sure this isn't a bug in JNA (the Java library that make calls to native libraries) can you try compiling our example C app to see if that crashes as well. And if the C app does crash, try different functions and tell me exactly which functions fail (and if any succeed -- in the sense that they don't crash).

Thanks for the quick response, Wyatt. Assuming I built the C Example correctly, I am still getting a SIGILL error in the libTurboActivate.so library. Here are the steps I took to build, in case I am doing it wrong.1) Copy Example.c, TurboActivate.h, my TurboActivate.dat, and libTurboActivate.so into a directory.2) Run g++ -o prog -Llib -Wl,-R,'$ORIGIN' Example.c libTurboActivate.so3) Run ./prog4) Output is "Illegal instruction"5) Run gdb prog6) Output is:Program received signal SIGILL, Illegal instruction.0x40039a30 in ?? () from /usr/testing/libTurboActivate.so(gdb) quit

I tried removing bits of the Example.c to get it to try to narrow down the problem call, but I found the only way it would stop erroring would be if I didn't include libTurboActivate.so in my g++ compile call. Not sure where to go from here. Thanks for any advice!

To clarify, removing the .so dependency also meant I had to remove everything from Example.c until all it did was output Hello world.

I tested the C program on our other board, and it is running properly, so I don't think I built it incorrectly. Still not sure how best to debug the .so for you though. Any ideas? Thanks!

I think the problem is likely that we're compiling for a newer version of ARM than your board. Looking at the info you provided it looks like your board only support ARMv4, while the ARM version of TurboActivate is compiled for ARMv7 (i believe, I don't have the ARM board in front of me).

You can quickly verify this by using "readelf"

readelf -A yourapp

readelf -A libTurboActivate.so

Then look at the following lines. They will look something like this for TurboActivate:

  Tag_CPU_name: "7-A"  Tag_CPU_arch: v7

Also, if you could send the full stack trace to wyatt@wyday.com, that would be helpful. Hopefully the failing instruction will be listed (or at least the address of the instruction).

I think this all boils down to ARMv4 vs. ARMv7. I'll see if we can compile TurboActivate with ARMv4 without harming its performance.

Also, is this a board/architecture you'll be realistically targeting for your app? How old is it? Which model is it (CPU model and board/phone model)?

Thanks again for your quick response. I will double check with our hardware guy on the system specs. I must have been mistaken about it. You look to be right though, according to the readelf outputs.

I will try to get you the stacktrace from the Example program. In the meantime, here is the Thread output from the error log that I didn't post before because it was too long. Not sure if it will help.

OK, this is a pretty old CPU (almost a decade old). Will your app be targeting old CPUs with the ARMv4 architecture? If so, we can work on supporting that with TurboActivate.

Yes, we are planning on using this architecture as one of our product options. Not the only one, but we definitely would appreciate an ARMv4 TurboActivate build if it's not too much trouble. Thanks!

OK, we'll try to get that out with TurboActivate 3.3. The schedule's a bit tight right now (we're shooting for an end-of-month release). If we can't get a ARMv4 version of TurboActivate in 3.3, then we'll make a quick release immediately after 3.3 (3.3.1, presumably) that will add ARMv4 support.

Thank you very much! Please let me know if I can be of any assistance to moving that along.

Just wanted to follow up and check on the progress towards 3.3. We are still in need of an ARMv4 solution as soon as possible as it is the only thing holding us back from being able to deploy with TurboActivate. Please let us know how we can help in terms of development and testing to get this working.

Hey Jonathan,

We can have a pre-release version of TurboActivate 3.3 (for ARMv4 Linux) out by Friday. The "final" version will be a little bit longer in coming.

Would you like the pre-release version?

That would make my new year. Thanks! Please let me know when we could get access to that.

Just an update: I'll send you the pre-release ARMv4 TurboActivate 3.3 later today. We still have some testing to make sure this beta version doesn't have any bugs in the existing features.

Edit, 1/7/2013: We're fixing some show-stopper bugs -- once we get these squashed I'll send you the pre-release version.

Thanks for your continued support! I look forward to getting the pre-release soon.

Just following up again regarding the ARMv4 pre-release 3.3. How is everything going? Is there an estimated delivery date? If possible, we would be happy with simply the libraries for ARMv4 support if they are ready. We probably do not need any 3.3 features yet. Thanks!

Unfortunately we can't just recompile 3.2.2 with ARMv4 support because we needed to make code changes to support ARMv4.

We're close to the pre-release version. We're stress testing the server changes that need to be made to support new TA 3.3 features (so we don't mess up old TurboActivate versions activating).

Thanks for the update, Sam. Happy to hear you are close.

How is the progress with testing? We are willing to help in any way to speed up the process. Thanks for your support!

We're almost done (all the tests thus far have succeeded). We have a few remaining. Then we'll send you the pre-release of TA 3.3.

Thank you very much! Definitely appreciate the continued updates of your progress.

TurboActivate 3.3.3 is out. You can get it on your API page. This adds (among many other things) ARMv4 support.
