I had mentioned previously that psim does blocking i/o by default, which
stalls the system when the polling ofw console driver does a read.
Psim can do non-blocking i/o if it's built with the right options.
- pass the '--enable-sim-stdio=no' option on the configure command line
- in the device tree, insert the line
/openprom/options/use-stdio? false
*after* the '/#address-cells 1', if it's present.
later,
Peter.
