Trouble updating CrazyRadio firmware

[floyd871]

I am runnig the Bitcraze-VM under Windows 7 64bit.
Flying ist i litte bit complicated, but i will figure it out!

Now i want to update the Firmware. I open a Terminal an enter:

Code: Select all

bitcraze@bitcraze-vm:~/projects/crazyradio-firmware$ python usbtools/launchBootloader.py
Launch bootloader ....
Error!, bootloader not started
bitcraze@bitcraze-vm:~/projects/crazyradio-firmware$ 

After that, the USB CR-Dongle just disapears form the VM and the Host!!!

Code: Select all

bitcraze@bitcraze-vm:~/projects/crazyradio-firmware$ python usbtools/launchBootloader.py
Error!, cannot find the CrazyRadio USB dongle!
bitcraze@bitcraze-vm:~/projects/crazyradio-firmware$ 

Who can help?

Did you follow the instructions on the wiki because the Crazyradio will appear as a new device?
"Once the bootloader is started the Crazyradio dongle will dissapear ad a new device named nRF24LU1P-F32 BOOT LDR will appear. If you do not have a filter set up for the bootloader in the VM then script will say that it failed. This is ok. Pass the bootloader device into the VM and continue."

Yes i have followed the instructions in the Wiki, but the New Device does not appear under the new name, so i can bind it in the VM.
Under my host OS (Windows 7) ist must appear as well, right ??

Yes it should appear as a device in win7 if the bootloader managed to start, but it doesn't?

[floyd871]

Yes correct. Under Win7 the Device ist gone no new device appear.

No i have tried with a different Computer at my workplace with running pure Linux (Ubuntu).
After a few problems with pyusb and missing udev rules, i have managed updated the firmware.

Now at home i have tried the procedure under Win7 and Linux-VM, but no change. After start of the bootloader (vm) the device is gone.
Wit a scanner in the Windows Host i did NOT see the Crazyradio device with a different id (0101) or the old (7777) one.

Did anyone do the update within the VM and a Windows Host?

I updated the firmware, but the problem is not solved.

Hi,

There was a bug in the firmware versions < 0.52 that could cause problems with updating from a virtual machine. But I'm guessing that you flashed the latest version (0.52) so that should be solved.

When I try this I still get the same messages as you do, but I get the new device as well. It's called Nordic Semiconductor nRF24LU1P-F32 BOOT LDR. I have Linux as host, but I'm running the Bitcraze VM 0.3 to launch the bootloader and flash the new firmware.

[floyd871]

Yes, i have flashed the last version (0.52). But under my Windows Host with the VM the Device is still missing after bootloader launch.

So, this might be a Windows problem.
