Mk2a killed by heat?

My friend left his empeg in the center armrest in his Jeep on a hot day. When he came back and plugged in the empeg, he got the dead Tux logo and the empeg hasn't worked since. I assumed the hard drive just died due to the heat.

He had a 40GB drive around, so without doing anything else, I put that in there and tried to flash with the disk builder. The process failed at "finding pump." The hard drive never turned on. That's when we hooked up his original hard drive to a PC and it worked fine.

Now my assumption was that the cable went bad somehow since the IDE header looks to be in fine condition. I just replaced the cable with a brand new one, and the drive still doesn't power up.

I suppose that since I have been unable to flash this thing, this is all I get from the serial port now:

Any ideas?

Okay. My recommendation for a starting point would be to unplug all drives and try to reflash a developer edition kernel. The drives being removed will eliminate them as a possible problem and get you back to a known starting point. Make sure you have the firmware loader running and ready (I usually use upload.exe from logoedit) before you plug the player in.

Did that, and the thing works now. I don't know what's going on. Here's the boot log. The empeg is playing fine right now!

I'd bet the flash dropped a bit or two somewhere. Reprogramming it fixed it.

We've have flash chips do similar things and then come good once reprogrammed. We've had them sometimes give a 1 and sometimes a 0. Once reprogrammed they worked fine for a while (years). The manufacturer did finally acknowledge a problem with these particular once. Maybe the heat just made it a bit worse. Remember flash memory is technically not non-volatile. It has the potential to lose bits over time. Normally we are talking tens of years, but heat is very likely to accelerate that.

Doesn't explain why the disk builder wouldn't go on though.

I can only guess that the timing was off and that the player had already passed the flash load test. Glad it is working now, though!!!
