I tried to flash a latest firmware from BitCraze VM6.0 into my CF1.0.
Now it just displays blue constant LED and none of the motors turn on start up.
On start the green and red blink just once and then the blue light stays on always.
Please give me a solution to this.

Hi,

It is currently very hard to brick a Crazyflie with the bootloader (understand: impossible unless you intentionally code, compile and flash a firmware to erase the flash ...) so it should not be bricked: The RED/GREEN blink you see is the bootloader that wait for a packet to start bootloading.

You can try to flash it again with a different firmware. For example the latest Crazyflie1 firmware is: https://github.com/bitcraze/crazyflie-f ... tag/2015.1

Hello,

Thanks for the early reply, but my CF doesn't start at all. The motors don't spin at all when you switch it on.
The CrazyRadio doesn't detect the CF.

Sorry I wasn't clear: Yes it look like you have flashed a bad firmware, but it does not seems you erased the bootloader so you can still re-flash a good firmware.

Using the client you can 'initiate cold boot' and restart the Crazyflie, it should reconnect the bootloader. You can try many times if it does not work. Make sure to fetch the latest version of the client in the virtual machine (there is a link on the desktop for fetching latest version) we have had bugs that prevented some versions to flash the Crazyflie 1.

Thanks for the help..Worked like a charm...

Nice, happy you fixed your Crazyflie.
