Boot failed problem and solution

Just wanted to share this with the community: I ran into an issue with the infamous ‘Boot Failed’ message on 3 different Macs/PCs. Then I ran into this post in the forums. The picture posted by one Anthony More showed one of the yellow doohickeys (technical term) laying flat underneath the chip. On mine, it was standing straight up. I flattened it and Voila! I have a working 1.3 FW using Midi Mapping 2.2.

Only took me, oh, 6 hours of frustration. Awaiting 1.4…

Very strange- Perhaps Michael, the engineer on that chip has an idea about why that might have effected your performance. I am thinking it was an un-related coincidence. Perhaps you could bend it back up and see if the problem re-surfaces?

Hi Ataru.

Thanks for posting

The yellow dohickeys - are you refering the the ones on the upgrade PCB, or the ones on the VCI PCB?

Perhaps you could post a link to the picture you are refering to?

Cheers

There was one other change that I might have erroneously ruled out: for the USB power, I plugged into another laptop, one different from the one that I was flashing from. My first thought was that could not have made a difference but unfortunately I was unscientific in my testing. Does the USB power have to come from the same source as the serial connection?

In the attachment below I circled the doohickey on the upgrade PCB which was standing straight up, just as the other two. I laid it down to reflect the attached picture and this is what, seemingly, made the difference (if it was not the USB issue I alluded to above).

Hmm thats interesting,

The photo make is look like its soldered correctly - does the joint (where it goes into the circuit board) look the same on both of its legs?

It could be the lead was broken inside the component and bending it fixed that but that is a pretty unusual failure mode.

I think it was probably changing the computer you used to provide power rather than the capacitor but thanks for posting that up any way

Both legs are fine. I verified that when I noticed the difference as I had run into CB problems after messing with things like that and using too much pressure breaking the contacts, so I was extra careful.

I am not sure how that can be the issue. They are separate functions, right? No signals related to booting get sent over the USB, I would think. Dangit, wish I would have done this more empirically!

Thanks for the response.
