<br>Yes, I get also a segmentation fault. For the leon3 it seems to work:<br>

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