|
|
Simulation context switching is based on logic like setjmp and longjmp. This
|
|
context switching is only available for 32-bit targets. On 64-bit machines,
|
|
this context switching will fail.
|
|
|
|
The workaround on 64-bit machines for now is to build for a 32-bit target on the
|
|
64-bit machine. The workaround for this issue has been included in NuttX 6.15 and
|
|
beyond. For thoses versions, you must add SIM_M32=y to the .config file in
|
|
order to enable building a 32-bit image on a 64-bit platform.

config SIM_WALLTIME

bool "Execution simulation in near real-time"

default n
|
|
---help---
|
|
NOTE: In order to facility fast testing, the sim target's IDLE loop, by default,
|
|
calls the system timer "interrupt handler" as fast as possible. As a result, there
|
|
really are no noticeable delays when a task sleeps. However, the task really does
|
|
sleep -- but the time scale is wrong. If you want behavior that is closer to
|
|
normal timing, then you can define CONFIG_SIM_WALLTIME=y in your configuration
|
|
file. This configuration setting will cause the sim target's IDLE loop to delay
|
|
on each call so that the system "timer interrupt" is called at a rate approximately
|
|
correct for the system timer tick rate. With this definition in the configuration,
|
|
sleep() behavior is more or less normal.
