I’ve spent several hours going in circles on this, trying in vain to get the system to see the FEZ Spider in loader update mode.
Using a Windows 7 32-bit PC with the latest GHI SDK freshly reinstalled yesterday, with the Spider switches in normal mode, FEZConfig sees the board and confirms that it needs both the loader and firmware updated.
But as soon as I connect the Spider in loader mode (last three switches ON), the device is not recognized. In FEZConfig, the status bar shows “No device.” In Device Manager, it shows up under the USB section as Unknown Device. I tried having it update the driver by searching in the GHI folder on my system, but it just says that it has the latest driver for “unknown device.”
If I attempt to load the GIH bootloader driver manually via the INF file, I get a message indicating that the driver cannot be installed this way. If I try updating the driver through device manager, and specify the GHI bootloader driver specifically, half the time it just says that the “unknown device” driver is already up-to-date.
Now, the other half of the times I do this, it SEEMS more promising, saying that a Windows restart is required. So, I restart Windows, and Device Manager shows the GHI Bootloader driver as COM3, but in a state of being “unable to start.” Disabling and re-enabling the driver ends up in the same “unable to start” state. Bringing up FEZConfig shows “No device” and if I switch to Serial mode from USB, COM3 doesn’t show up in the list.
On the rare occasion that I see the “unable to start” GHI Bootloader driver in Device Manager, as soon as I press reset on the Spider, the GHI Bootloader device disappears, and the USB Unknown Device reappears.
A seemingly vicious circle. Any ideas how I can make more progress toward updating the loader on the FEZ Spider?
