gdbserver - illegal instruction

[Mobile Enthusiast]

Hi,

I'm trying to run gdbserver on the Neo Freerunner, but I keep getting
an illegal instruction error. It might be because the gdbserver
executable i'm using is the one from the prebuilt/android-arm/
directory and that's armv5 whereas I need armv4.

Question:

How do I confirm whether this is indeed the case?
Where can I get a gdbserver executable that is armv4?

I tried cross-compiling, but that didn't work. May have done something
wrong with my cross-compile, but I'm not sure. If suggestion is to
cross-compile for v4, can anyone point me to a resource? They've been
scarce.

Appreciate the help.
Thanks.

In particular, where is the source for the the gdbserver executable
included in prebuilt/android-arm/gdbserver/ ?

The README.txt in that directory says:

To compile a new gdbserver, see
//toolchain/gdb/src/gdb/gdbserver/README_ANDROID.txt

But there is no toolchain/gdb/src/ directory in the source tree.

Presumably if we had the source we could build an executable with our
armv4t toolchain.

Looks like someone removed gdb from the source tree back in November.
I downloaded the snapshot for gdb specifically, but now i'm having to
cross-compile again. Any ideas of how I could do that with the armv4
toolchain (prebuilt/linux-x86/toolchain ...)

Thanks.
