Re: ardrone_usb_bootloader.bin

How long does the firmware upload take? I am sitting here for 5 minutes? Normally ~60 sec. If it lasts that long, something is wrong. Ensure that your USB connection is good and the battery is full. Also connect the drone to another USB port, then try it again. Secondlly where do I get a telnet cab...

Re: New Problem: Motor LEDs off after boot

What is the output of program.elf?

Try:

killall -9 program.elf
program.elf > /update/program_elf_dump.txt

And attach the logfile please.

Best regards

Re: ardrone_usb_bootloader.bin

I guess thats what the log was telling us ?
Yep, exactly. program.elf's output is quite helpful in case of red lights.

Re: ardrone_usb_bootloader.bin

Connect via telnet to the drone, call the following commands and post the output here:

mount
dmesg

Then, please call:

killall -9 program.elf
program.elf > /update/program_elf_dump.txt

Connect to your drone via ftp (port 5551), copy the dump file and attach to this thread.

Best regards

Re: ardrone_usb_bootloader.bin

The bootloader is correct. In your case, it was not even possible to connect to the stage1 bootloader (the bootloader that is stored in the internal ROM of the P6 chip). If you cannot connect to the stage1 bootloader this might be related to a bad connection. Also ensure that the battery is full. Wh...

This means that your drone does not respond to the initial USB command. How did you build the USB cable? Maybe the connection is not good enough.

Re: Utility to reflash firmware / obtain installer plf with

Good work, thamind. Just two things: 1. To comply with the GPLv3, you should either refer to the source code of the tools (http://code.google.com/p/ardrone-tool" onclick="window.open(this.href);return false;) or add the source code directly to the zip file. 2.

Re: ardrone_usb_bootloader.bin

You need to downgrade your firmware. I heard there is a bug with the latest firmware version. You can get the older firmware here: http://www.ardrone-flyers.com/wiki/V1.4.7" onclick="window.open(this.href);return false; On the main page of the wiki, you can also find older versions which you may tr...

Re: Broken NavBoard?

(I guess program.elf will send something to /dev/ttyPA1 once it received that AT command) This was also my first assumption, but ttyPA1 is dead once a Cutout was detected. As they use a single-wire UART for motor connection there must be some open collector circuit. I assume that this circuit is de...

hi everybody! any news on sniffing BLC protocol? I've used the following command cat /dev/ttyPA2 > /dev/ttyPA1 hoping to use continuously streaming navdata to get any response from motors but all I got was a lightshow with diodes. will try to use interceptty Yes. MAPGPS provided me an interceptty d...

Re: USB Disk on AR.Drone

I have stil another question, I managed to flash the drone on my Windows computer, but now I would appreciate to do the same thing with my linux computer (with ubuntu 10.10). I built the usb_flash_tool, but I don't know how to add the drone as a usb device (that was very straightforward on windows,...

Re: Motherboard diagnostics - Logs

What I'm guessing is that maybe there is a problem with the soldering in the BGA chips (I think some people had problems with that) Hm.. really sounds like damaged balls for your board. You could try to apply pressure to P6 or the DDR RAM. You could also try to boot a kernel over USB. You just woul...

Re: Diagnostics - Boot Sequence - TTL to RS232 IF

Did you encounter any problems when connecting this to your drone?

Just wonder because P6's ttl voltage is ~3.3V while your converter operates at 5V. So at least for Max232-Tx -> P6-Rx you would apply 5V to your drone.

Re: Broken NavBoard?

After a few hours figuring how to compiling static interceptty (autoconf and automake is something unknown for me) I've been able to run it on the drone. And it worked as expected and I could sniff data from ttyPA1 (ttyPA2 is broken, this thread started on that) and get the some interesting stuff. ...

But you won't be able to dump ttyPA2 a...
