Continuous red instead of quick blinking after uploading pilot021.arm on ftp root

Hi everyone

I have successfully installed mirumod with GPS and it works fine with my turnigy 9X.

My problem started when I uploaded pilot021.arm on the root folder using an ftp connection. When I did that the drone did not boot properly, it ended up having a continuous red light on the arduino.

I had to delete pilot021.arm from the root folder to make the drone boot up properly again with mirumod.

Any ideas why this happens?

I have checked Q11 in mirumod's webapage (i.e. My MiruMod's LED flashes as it should when booting, but then stays solid bright. What's wrong?):

- setup mode works just fine
- MiruMod is plugged in correctly. I suppose the fact that it works when pilot021.arm is not on the root folder proves that.
- no loose, broken or disconnected cables going to/from the MiruMod/LevelShifter/Drone plug
- ls -l /tmp - this returns a list of files which does not include at2so.arm.

I would appreciate your assistance!

Thanks
Yiorgos

Did you do a 'sync' after the upload of pilot021.arm to /data/video?

I was not aware that I had to do a 'sync'. Do I type SYNC at telnet after having uploaded pilot021.arm with ftp?

Yes, but use lowercase... and do it right after the ftp before you cycle power to the drone.

It worked! Drone boots normally now and arduino lights quick flash as previously. Thank you so much!

Receiver error signal delay MAX value of 8.3sec

Why is there a max limit for this parameter?

I am planning to fly the drone over the sea and I would prefer that it doesn't land if the signal is lost. If it stays in the air I will have some time to think how I can get closer in order to restore the signal. Obviously 8.3 sec is much better than 0sec but I would prefer if I had let's say 60 sec.

What will happen if I define this parameter with values > 8.3 sec?

You will get a truncated value, which is not what you expect!
The 8.3 seconds come from the loop running at 30 Hz and the erx variable beeing an unsigned char variable (1/30 * 255 = 8.5). You could make the erx variable an unsigned short (u16_t) and change the MERX macro to (u16_t)((double)LOOPHZ*(double)60.0+0.5). Don't use the SL2TIC() macro, it typecasts the result to an unsigned char!

Hi MIRU,

which value/line do I need to change in order to increase the delay to 5 seconds?
Do I need to change this line to:
#define S2LTIC(s) (u08_t)((double)LOOPHZ*(double)(5)+0.5)?
Or what do I need to change?

NO, please don't! Check line 61:
Code:
#define	MERX		S2LTIC(0.5)
and change it to
Code:
#define	MERX		S2LTIC(5.0)
