Has the same problems with interger overflow during compilation as described Description: The Has the same problems with interger overflow during compilation
for pjrc-8051 as described for pjrc-8051. At typical cause is code like
usleep(500*1000) which exceeds the range of a 16-bit integer
Status: See pjrc-8051
Priority: See pjrc-8051
Description: The simulated serial console (configs/z80sim/src/z80_serial.c +
driver/serial.c) does not work. This is because there are
no interrupts in the simulation so there is never any serial
traffic.
Status: Open
Priority: Low -- the simulated console is not critical path and the designs
to solve the problem are complex.
