HITL jmavsim fail

[yiwc]

Describe the bug
I follow http://dev.px4.io/en/simulation/hitl.html
but meet error.
It can obviously get RC signal, I can easily see it arm and disarm in the qground. I can also see it
'MSG: Landing detected'
and
'MSG: Takeoff detected',when I control my RC controller.
but virtual copter moves nothing in the Jmavsim simulator. Virtual copter keeps staying still.

I tested it indoors, is it a problem about GPS thing? If is, why there is also no reponse in Z direction.

Expected behavior
Virtual copter moves as I control with RC Controller.

Thanks for your team's work

What target have you flashed on your hardware? Could it be px4_fmu-v2_default?

Thank you for focusing on my problem.

I flashed px4_fmu-v2_default . Because my hardware is Pixhawker.(pixhawk1)

Ok, so the problem is that for v2 there is not enough flash space. What you have to do is to enable pwm_out_sim here:
https://github.com/PX4/Firmware/blob/ef54bff4ed45755b4762ef58db21fa37d612d44e/boards/px4/fmu-v2/default.cmake#L50

Then it will overflow of space, so you need to deactivate some other modules such as fixedwing (fw_) or vtol (vtol_).

Also, you can check if you really do have the silicon errata which limits you to 1MB of flash instead of 2MB by doing ver all in nsh>.

More info here:

Thanks
I follow your advise, unfortunately it doesn't work.
It still have somehow problem.
CRITICAL NAVIGATION FAILURE - CHECK SENSOR CALIBR

PS.

1. I try to update bootloader, it still be v2. I guess it can't be updated to v3.
2. My hardware has 2mb flash, I use
   make px4_fmu-v3_default force-upload and
   make px4_fmu-v2_default force-upload (for overflowed v2).
   But both failed in CRITICAL NAVIGATION FAILURE - CHECK SENSOR CALIBR

You have this problem #11179.

[yiwc]

Amazing, I follow your advice:
1.Enable pwm_out_sim. 2.And I pull the latest PX4 Firmware as told in #11179 #11104
The virtual copter successful flied!

BUT, there is a strange thing.
HITL only works when it is the first time HITL after flash new firmware. Strange, right?
It's like this
| flash Firmware
| HITL (working!)
MSG: RECOVERING FROM FMU IN-AIR RESTART MSG:Failed to recover from in-air restart (1), abort MSG:RECOVERING FROM FMU IN-AIR RESTART MSG:ARMED by arm/disarm component command MSG:Failsafe enabled:no RC Init MAVLink
And after arm, it works fine!

| close HITL, and reboot vehicle
| HITL (not working)

| reboot again
| HITL (never working again)

Based upon: v2, I use make xxx force-upload to upload it. (my hardware has 2mb flash)

-----------------------Line----------------

I use
make px4_fmu-v3_default upload HITL works.(I can use v3, because i followed update bootloader. Evan though QGround still shows I'm using fmu_v2, but when I 'make px4_fmu-v2_default upload' It tells me should use "px4_fmu-v3_default")

Anyway, HITL works anytime! So it solved for me.
Thanks for your help.
If interesting, strange problem above the --line-- can be looked into.

| HITL (not working)

When HITL is not working, does also unplugging it and re-plugging it not work?
