Cobra II Firmware Update

Archive
1

I have updated the firmware on my cobra board to the latest firmware. The update went smoothly.

Now I get USB device not recognised. I am using windows 8.

I have tried device manager; driver update and allowed it to search the GHI folders and sub folders but it has not been able to fix it.

I have problem with my cerberus on Windows 8, it helps to use external power and hub usb … but sometimes ! On my hub only few ports permits to use board. Why ? Ports are différents ? No ! I could only see some works and some doesn’t !

If you could try with hub usb, with external power. Idealy, find a Windows 7 computer 8)

At the point I pressed reply … I had plugged into a different port on my usb hub and windows popped up and installed the driver. The device appeared in VS … looked great and then it disappeared …

Now finding a power supply!

Power supply made no difference either! :wall:

And windows 7 is not an option! my development laptop is windows 8 …

Windows 8 is not a problem in general. I mostly use Windows 8.1 (update) x64 computers.
But when ever possible I use USB 2.0 ports and an extra power supply.
Once I had a similar problem, but reinstalling the SDK (and with it the drivers) solved the issue. Don’t forget to reboot after uninstalling the SDK.

I had something similar.

Try updating TinyBooter on the device manually and then do the erase during this and then use Fezconfig to update the firmware.

After this I was able to use both Cobra 2 boards and 3 customs G120 boards.

Hi Dave, I how do I do the tiny booster manually?

My question also, as the device driver cannot start and any connection to it is dead…?

Windows keep cycling the message USB device not recognised, so I don’t think the cobra is dead, just windows does not appear to have the correct driver? When I tried a different USB plug windows detected and installed the device driver, it appeared in VS … But shortly afterwards dropped out.

Hi Dave,
I have done the manual task with teraterm. Cobra still connected. When I now use fez config to update sdk … it does not list any options; so browse to fimrwares … there are 3xhex files … config, firmware and firmware2 … which do I select?
Thanks

All

You don’t need to select the files.
All listed files together are the firmware.
The will be used, no matter what you select.

Interrupt while deploying update failed?

15

I have 2 FEZ Config folders … have tried the other and it has been successful … now to see if I can deploy a solution

Solution Deployed …
Many thanks

I was going to say, don’t connect through a HUB, connect direct. I’ve found that you can debug through a hub no problem but firmware updates have only been reliable on direct USB ports.

Glad you got it sorted though.
