Segfault when executing example PWM programme

[LucasKl]

Hello,

i followed the tutorial and succesfully compiled the verilator emulator with the PWM.
However running the emulator with the example code always leads to a segfault.

Is there anybody who had the same issue already and might point me in the right direction?
Any help is very appreciated.

Thanks,
Lucas

The pwm program doesn't use pk. It's meant to run baremetal.

Ok thank you for helping me here. How can i write to the pwm registers with the proxy kernel? I tried writing to /dev/men but that doesn't seem to be working.

Thanks,
Lucas

Hello,i followed the tutorial but have problem compiling the verilator emulator. When I run make in the "verisim" directory, it shows sbt.resolveexception unresolved dependency edu.berkeley.cs#firrtl_2.11;1.1-SNAPSHOT
Have you met this problem? Can you help me with that? Thanks.

You need to go in the firrtl folder and follow the README there.
It's important that you not only build it but also run something like sbt publish local (not sure if this is the exact command, pls check the README)
