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 those 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.

Older versions of Cygwin tools decorated C symbol names by adding an

|
How do you know if you need this option? You could look at the generated
|
|
symbol tables to see if there are underscore characters at the beginning
|
|
of the symbol names. Or, if you need this option, the simulation will not
|

run: It will crash early, probably in some function due to the failure to

allocate memory.

RDI, RSI, RDX, RCX, R8, and R9, while XMM0, XMM1, XMM2, XMM3, XMM4, XMM5,

XMM6 and XMM7 are used for floating point arguments. For system calls, R10

is used instead of RCX. As in the Microsoft x64 calling convention,

additional arguments are passed on the stack and the return value is stored

in RAX.

Registers RBP, RBX, and R12-R15 are callee-save registers; all others must

Under simulation, a NuttX port can be bound to a serial
|
|
port on the host machine. This way NuttX can access the
|
|
host's hardware directly.
|
|
|
|
There are two possibilities regarding the host's port:
|
|
it can be either a physical one, or a simulated one.
|
|
|
|
In case of a physical port, NuttX will be able to open
|
|
this port and communicate with any actual hardware that
|
|
it is connected to. This is useful for testing code that
|
|
uses external hardware (e.g. sensors or other boards).
|
|
In order for this to work, NuttX port name must be set to
|
|
the same name that the host is using for this port (e.g.
|
|
/dev/ttyUSB0).
|
|
|
|
Alternativelly, a "simulated" host port may be used to.
|
|
This is useful if you need to also simulate the external
|
|
hardware, or to have NuttX communicate with any other
|
|
software in your system.
|
|
You can create a "simulated" port in your host,
|
|
by running:
|
|
|
|
socat PTY,link=/dev/ttySIM0 PTY,link=/dev/ttyNX0
|
|
stty -F /dev/ttySIM0 raw
|
|
stty -F /dev/ttyNX0 raw
|
|
|
|
This will create two new ports on your system.
|
|
NuttX will use the ttySIM0 port, and another software
|
|
may open and use the ttyNX0 port.
|
|
Anything sent to the one of these ports will be relayed
|
|
automatically to the other, and vice-versa.

|
Get Raw Gadget:
|
|
Get Raw Gadget code at https://github.com/xairy/raw-gadget.
|
|
|
|
Make Raw Gadget:
|
|
Run make in the raw_gadget and dummy_hcd directory. If raw_gadget

build fail, you need to check which register interface meets your
|
|
kenel version, usb_gadget_probe_driver or usb_gadget_register_driver.
|
|
|
|
Install Raw Gadget:
|
|
Run ./insmod.sh in the raw_gadget and dummy_hcd directory.
