I think I found it. A hacky fix/workaround is to add the following
line to the beginning of out_char() in src/lib/uart/uart_cadence.cc:
     _regs->write<unsigned>(ISR, IXR_RXOVR);

The proper change is different.

It segfaults when executing init. One common reason is that VFP support
is missing in Linux. Strike?
