Bricked and recovered, but what went wrong?

[Guest steveg100]

Hi guys,

So I had Modoco's build installed and had been using it with no problems for a couple of months. While on holiday I put it into USB master mode and connected the vega to my friends Nikon camera with the intention of looking at the photographs on the SD card. The screen went blank and that was it. Rebooted, still just a blank screen.

I've just managed to put it into recovery mode and install the default Advent build, but I'd like to know what happened. Any clues? Given the struggle I had to get it working again, I thought I'd check with the great and good here before trying again.

I assume you did not install another kernel? The USB switcher in the MoDaCo ROM works only with the MoDaCo kernel.

If you did not change the kernel, then it sounds like BSOD, there is a fix here that avoids that, search for BSODFixer.

HI Beegee, thanks for replying

Correct

The USB switcher in the MoDaCo ROM works only with the MoDaCo kernel.

I'm pretty sure I used the USB switcher that came with the MoDaCo kernel.

The post I found for BSODFixer are all about using it to restore the vega, wich I managed to do by reinstalling the standard build. I'm just reinstalling the MoDaCo build now.

Which has now finished. So I used the USB switcher to put the vega into host mode. It rebooted just fine. Plugging a USB stick in and it works fine. Very strange. I wonder if it was something to do with the camera itself. I'll have to wait till I see my mate to try his camera again. I'll post again if the same thing happens. If not, I'll chalk it up to an error between chair and keyboard.

Thanks for your suggestions.

It's to do with the switching.

When switching between usb host and slave, you switch kernels (as it's hardcoded there). In doing so, you mess up some instruction alignment I think and so it wont boot properly.

The fixer just attempts to reflash the slave kernel, and in doing so resolving the mess up.

That's why when you switch to host and reboot, it crashed, but if you just flash the old slave back, it'll work.
