An illegal instruction was executed!

I did apply the patch and rebuild pk (configure, make and make install).

I have a problem when running the Proxy Kernel test with the emulator:

$ ./emulator-freechips.rocketchip.system-RoccExampleConfig pk ../rocket-rocc-examples/build/pk/examples-pk-accumulator
This emulator compiled with JTAG Remote Bitbang client. To enable, use +jtag_rbb_enable=1.

However, the baremetal test works fine:

./emulator-freechips.rocketchip.system-RoccExampleConfig ../rocket-rocc-examples/build/bareMetal/examples-bareMetal-p-accumulator
This emulator compiled with JTAG Remote Bitbang client. To enable, use +jtag_rbb_enable=1.

Using spike, I got this:

Any ideas?

Haven't had a chance to test this on my end. Were you able to sort it out?

[chenxuhao]

yes, I've resolved it. It was related to the install path of pk. Thanks!
