LPC2xxx / Solved!

...but then the end is, well, a good story.

So, at the same time I upgraded my Linux machine to the 12.04-based Mint Maya/Cinnamon, I also did some external cleaning up outside my lab. Part of that was getting rid of a 230 V extension cable and connecting the electric fence unit to an outlet just beside my window.

The same outlet that also power my lab equipment...

And there you have it, as I slowly went back in my trace, everything works like a charm, 12.04LTS/Mint Maya/Cinnamon/VB/XP/FlashMagic!

So thanks for reading, this took me too much time and frustration.

Horses are dangerous!

(and the fence will be powered from another building)

No, the Mac OS version is not for 2387 ;-(

However, I just once succeeded to get response on the "?, Synchronized..." and I only twice got the sequence going using 9600 b/s + debug and probably failed the other 98!

I think it may be a faster to give it all up and dig out the netbook, it takes too many attempts to try to figure out some kind of repeatability. At this moment I have no clue at all why it has worked a couple of times.

Will give to another try tomorrow. There may be something about timing, though. Perhaps disconnecting the 1920 x 1080 screen will improve things?

Edit: After a good night's sleep thinking about it: Since I do not get the expected response from the board when I feed it with the 9600 b/s "?"<CR><LF> sequence, well, that tells me that the problem is not at all FlashMagic. The next step would obviously be to connect an oscilloscope and find out what is actually showing up on these pins. After all, 3 bytes, including stop and start bits, is only 30 bit times and it is not too difficult. It may very well be that the problem is more centered around the FTDI Linux driver...

So nice to get a response, thanks!

Yes, it used to work so well. But there are so many variables and so many updates so it would be very simple if it was easy to pick a combination that works. Perhaps a 10.10 install may solve the problem...

But thanks to the information here in different posts I now realize that there is some kind of functionality, I will keep experimenting and will let you know.

I also realize that supporting anything else than Windows is a bit "off topic", but then again, it should work, shouldn't it?

Well, despite the fact that there is a lot of people out there, the community running FM under XP under VB under ubuntu is not massive ;-)

However, we have done just that and it used to work perfectly. The text needed to give only a brief background is rather lengthy, so instead of repeating it here, please have a look at http://jangoteknik.se/weird-linuxvirtual-boxxpflashmagic-problem/.

Yes, we have tried debug mode and we have read all relevant posts here. The obvious solution is to dig out the little XP netbook and try native XP, but it is so extremely frustrating to know that it worked like a charm only a few days ago and that something then got broken.

To clarify, the sequence ?, Synchronized, 14475 as described elsewhere here behaves like expected she we try it at 9600, but all attempts to get any further using FM fails. As I try again writing this, I actually find that being in debug mode and disabling high speed it is actually programming. Utterly slow, but still...

But you are not alone out there, only almost...
