Problems with the ground plane seem likely, but I doubt it's the wall plug (the rect/ vreg oughta fix that). More likely you have a solder bridge somewhere or you've already cooked something. The ground plane is just a reference point for other voltages in the circuit... it doesn't need to be exactly related to the earth on the wall plug. I won't go too far into that, it's been covered before. Half? as in, the pot is half way? Do you know that all-the-way-left is 0 and all-the-way-right is 50W? How long is "shortly", roughly, in seconds? Did you use that iron an this board or parts before you got the new one?

What about cabling? You didn't say which cable you moved and which stayed attached to it's core.. What app was that above? Have you done this: srio_interconnection_test_v1a.zip ?

LOL, me too, etc *whack*

YAY!! (Finally a straight answer :D ) Yucky. What about the what comp? that looked much nicer.

Yes! Thanks :) I seem to remember that all of those images were animated, and there were sounds ... Fox probably tore it down from youtube ;)

Click link to ucapps page, scroll down, you'll see MIDI Troubleshooting near the bottom... or Click the search link, type midi troubleshooting, hit 11 is LINK TO MIDI ISSUES or Start at forum front page, scroll down to Testing/Troubleshooting, and you'll see the above link as a sticky thread. Seems easy enough to find where it is ;) It takes some time of course .... Only took a minute for me to find it three different ways, but of course I'm familiar with the site... that's why it's important to read lots, it's not just the stuff that 'sinks in', it's also the stuff that gives you a 'feeling' of where things go... It's like getting to know someone's kitchen; I wonder where this guy keeps the beer glasses? Probably the same place he got that wine glass from ... Serial makes it larger, parallel makes it smaller. Anyway, now we know that it was a dodgy midi interface, What kind of midi interface is it? I don't suppose it's USB, and running off a hub? (I'm trying to think about why it may be underpowered aside from just being faulty... maybe it can be fixed)

Oh it's a 'jeopardy' game: What is the acronym for "Bit Test F, Skip if Set" ? ;D

The jogs are actually rather nice... Thick plastic with a nice matte finish and texture, not too big not too small... I like them anyway :)

Have you done the midi troubleshooting procedures at ucapps.de? If you do those, and get the results of all of the tests, it will give a very strong indication of the cause. Good luck, let us know how it goes!

Who the f*ck is that guy? what a n00b!

Welcome aboard. No, you do need midi to upload mios and apps. You can't burn them. Yes, you can skip the opto. But it's there for good reason. Patience is a virtue. You should wait, in my opinion. You'll live.

LMAO! That was the fastest descent into lunacy I ever saw, very entertaining :)

No not true. It can be corrupted without stopping MIOS from loading later on. It just means that those parts of it are fully functional. Just cause the engine runs, doesn't mean the car has tyres ;) As I said though, such corruption is rare, and I don't believe that primary BSL corruption is to blame at all. yes, you are ;D I know what you mean about the behaviour of the core though, I've seen it before (in fact, I could make it happen right now by dropping the voltage on the PSU by 0.4V and uploading an app) But remember: The primary BSL sends the first upload request. You obviously don't believe me and don't want to try it (that's wise!) so take TK's quote from the BSL page on ucapps: It's already implied from the above, but I'll quote the newbie page too: So when you upload MIOS, you're uploading it via the primary BSL. So, it's not receiving the upload request, from the primary BSL... Why? OT where does jidis say he did the manual upload there? Doesn't change my point anyway so I'll go on.... Don't get me wrong - I've busted up my cores on several occasions by uploading stuffed-up custom apps, or by uploading to a core via bad interface, or with bad power, or PC problems, and I've seen the exact symptoms you refer to. Unlike you however, after fixing it, I knew that the problem was not with MIOS studio (or smart mode) but with my setup, so I went looking to find out exactly what the cause was... It's been a few different things (including weak power supply, shorted wire, bad midi interface, bad java install, and leaving motion detecting webcams running and maxxing out the CPU so that java (being the resource hog that it is) was too slow to respond to the upload request/checksum. So, having read the quotes from TK above, maybe you would like to re-read my posts, and you'l see what I meant... You can only upload MIOS via the primary BSL. MIOS does not overwrite the primary BSL. So, If the primary BSL upload requests/checksum responses are not working, Uploading MIOS won't change it. So you could only fix it by uploading the primary BSL update. The primary BSL update and MIOS upload use the same mechanism (for the upload procedure anyway, the incoming data is stored differently but that's not relevant), so, If uploading the primary BSL update works Then uploading MIOS should work Now, if your MIOS bootloader (secondary) is failing, so you can't upload apps, Then you may have a dodgy MIOS installation, Which means that you'd still want to update MIOS, Which means you'd be uploading it via the primary BSL But the primary BSL bootloader is functioning correctly, So it should work in smart mode too. But, as you have pointed out, we are not the only ones to have had this problem with the upload... And we've both fixed it by doing a manual update, and there are others... But there are also others (inc myself) who have had the same problem, and fixed it in manual or smart mode, with or without 'wait for upload..' ticked.... So it could be argued that manual mode makes it work, or that smart mode makes it work, or whatever makes it work - but that's all coincidence. Most of these case come down to the same situation as yours: An unknown fault which happened to go away for some unknown reason. It's easy to come to the conclusion that using manual mode fixed your problem, because it kinda does... I'll use another automobile analogy to demonstrate the flaw in that logic: You're driving along and smoke comes flying out of your hood, and you pull over. It seems like the engine is overheating. You wait a while, and check the radiator fluid, and it's low, so you fill it up. You start the car and drive, and it runs smoothly, so you say, "the water was low, and so it overheated". Some weeks later, you are driving along, and smoke comes flying out of your hood again. You check it again, refill it, and drive away. Darn thing always runs out of radiator fluid. Few weeks later, same thing happens. This is when you get frustrated and take it to the mechanic. When you come back the next day, he tells you that he has replaced an instrument in the dashboard, and refilled your engine with oil. You say "WTF, it was the water?! You're trying to fool me!!" ....and he says, "no, the oil was low, so it was overheating when you drove down the highway, so it was thinning out and causing increased friction, causing the smoke - and when you stopped to refill it, it cooled down because it wasn't running, so it worked after that. You just didn't see it because the oil temperature gauge was broken, so I replaced it. This model of car always leaks radiator fluid, just carry a bottle in the trunk." Think about it ;) Edit: Added the word "primary" in front of "BSL" a few times... I tend to refer to the primary bootloader as the BSL and the secondary mios loader as the MIOS bootloader... thought I should remove the 'slang' for clarity. Edit2: Damn I found two more! hahah

Hahahaha has it really been that long? time flies around here huh! Good to see you guys returning, don't be strangers now :)

HAHAHAH Yeh thx nilly!

I bought the hakko 936 ESD model clone, and wrist and ankle strap, and hoped like heck they work as advertised ;) (BTW, if you're standing/sitting still and soldering for a while, use ankle not wrist straps, it keeps the cable out of the way)

Now you're talking about the cause of something different... This time, you are talking about the cause of the core becoming faulty... I was referring to the cause of 'smart mode' not working, when another method does. There are some occasions where this could be possible, with some very rare and exact corruption of the bootloader*, but more likely, is that there's another problem with your setup which prevents a clean upload. Moreover, even if you do manage to upload MIOS to a bootloader which is corrupted in this very special manner, you won't fix the problem - MIOS doesn't overwrite the BSL, so it will remain broken. *Really really rare. Bordering on impossible. You have a better chance of winning the lottery twice in a row ;)

danke! das ist ein nicen midiboxen, ja? LOL ;D

Time to ask yourself why that is... You haven't solved the problem yet, you've just worked around it. I'm gonna guess that you've got a dodgy java installation, but I'll leave the 'fun' stuff up to you ;) He doesn't mention smart mode: matrigs' "unexpected upload request" messages, mean that his core was not receiving the uploaded data. He hasn't really solved the problem yet either, because he doesn't know why it wasn't getting there. He said it eventually 'just worked' and doesn't know why that one worked either. In his case I suspect a dodgy midi interface or core misbehaviour (voltage maybe). Whether you use smart mode or not, when the PIC sends that message, the upload has already failed.

Yeh, avoid vista, dudes. I don't like to weigh in on OS wars, but I do like to stop my buds from dealing with bugs ;)

Anti static wrist/ankle straps (grounding straps, whatever) are nice and all for stopping static transfer from you to the device, but they won't help the tip of the iron...

Errr...sysex data bytes must be 7bit maximum. If you want a reference other than me: System Exclusive 'course, you can send a 10bit value in two 7bit data bytes, with room to spare.

Nice find! I'd like to see what could done with these cheap parts :)

There are a fow excellent soldering tutorials linked from these forums... use the Search :)

Huh? Sorry cimo but that's a recipe for trouble. MIOS Studio smart mode=on, should do the exact same thing as smart mode=off or midi-ox or whatever, but with added error checking. Normally, when someone presents these kind of issues, the first thing I tell them is to turn ON smart mode. Of course, it's important to have a properly working midi interface and java client, etc. as well...
