The TWR-KV10Z32 development board works fine with an external crystal (default). We set the configuration to not use the crystal . CLOCK_SETUP == 0 and it would not run at all. We tried running other setup configurations which worked better but would not run reliably and crash after 1-10 minutes.
We have used other Kenetics processors which work fine with internal clocks using the same set up.
Is there a sample setup for internal clock we can try. We are using KEIL..
