The covoar needs the .cov files to run which is supposed to be generated by
a command like
this
====
$HOME/development/rtems/5/bin/sparc-rtems5-sis -nouartrx -r -tlim 600 s
-cov
$HOME/development/rtems/kernel/erc32/sparc-rtems5/c/erc32/testsuites/samples/hello.exe
====
But this runs into a segmentation fault. If my command is right (Please
correct me if it isn't)
then I think it's because the sis coverage is not supported for erc32. :/

about rtems-test,
I have attached a patch that adds erc32-sis-cov.ini, this will fix the
KeyError you're seeing,
but it will return with error 10 as it's trying to run the above command.
If you run rtems-test
with `--no-clean` and `--coverage` options, you'll have a
erc32-sis-symbols.ini file (and the .cov
files, when they're supported, like in leon3), which can be used to run
covoar directly like
below ( but this won't run now as we don't have .cov file )

covoar -S
$HOME/development/rtems/test/rtems-tools/tester/rtems/testing/coverage/erc32-sis-symbols.ini
\
-O coverage
-E$HOME/development/rtems/test/rtems-tools/tester/rtems/testing/coverage/Explanations.txt
\
-p RTEMS-5 sparc-rtems5/c/erc32/testsuites/samples/hello.exe
