Where to ARC Welder extrude “minidump file(.dmp)”?

问题

Im debugging Android app(emulating by ARC welder) on Chromebook, and often get "plugin crashed: captured minidump" message.

But I dont know where to extrude the "minidump".

https://www.chromium.org/chromium-os/packages/crash-reporting/debugging-a-minidump I saw this link, however cant find "minidumpfile(foo.dmp)". In my Chromebook, only those binary files in directory(/usr/bin/).

core2md, minidump-2-core, minidump_upload, minidump_dump, minidump_stackwalk

Because I cant find dumpfile, cant extrude corefile. What am I missing? What should I do?

How do you debug ARC minidump?

回答1:

Generate core file Convert a minidump to a core file.

sh -c '~/chromiumos/chroot/usr/bin/minidump-2-core -v upload_file_minidump-7adc2ee0079cb374.dmp > minidump.core 2>minidump.core.out'

For a minidump from a 32-bit executable, use minidump-2-core.32 instead.

For an ARM minidump, you have to work a little bit harder to get a core file. The easiest way is probably to do the conversion using qemu within your chroot.

# Convert minidump to a core file in /tmp/
SYSROOT=/build/daisy
qemu-arm \
 ${SYSROOT}/lib/ld-linux-armhf.so.3 \
 --library-path {SYSROOT}/lib: {SYSROOT}/usr/lib \
 ${SYSROOT}/usr/bin/minidump-2-core \
    -v ~/test/upload_file_minidump-de1f11232d825812.dmp >/tmp/minidump.core 2>/tmp/minidump.core.out
