haven’t been working on my Midibox for some time and then i wanted t ostart again and first time i tried transferring my app via MIOS Studio i get the following error which i can’t resolve. Have tried with the bootloader switch, but i still can’t get it to write. I am getting two error codes (-2 and #4). Can’t find anything about either - when trying to set the forum with -2 it doesn’t really work.. Anyway, i’ve uploaded a screenshot of the problems.
Weird thing is that it can obviously connect to the Core, see that it is LPC1769 etc. But when i try to transfer app, it fails.
Any documentation anywhere of error codes? I can’t find them anywhere.
Hmm… it is a quite uncommon thing… maybe something wrong on the core board? I’d suspect maybe some misplaced component somewhere or an unwanted solder bridge, that drops USB voltage, so the flash fails… but… fishing in the dark ;-). Can you measure USB voltage and 3V3 voltage with a voltmeter? Maybe someone else has a better idea!
I should try that. Will do that when i get back to my workspace.
Hmm - i used it for a long time where i flashed it many times and it was working flawlessly. No problems communication with it at that point.
Then i had it standing around for 5-6 months, and then recently i tried working on it again and then this problem..
So i’m thinking it can’t be a misplaced component.
Will try the voltage checking next time i get a chance and report back.
But isn’t there some doc. concerning error codes? Will try searching the code repo. when i have a chance of getting it down. Google searching the SVN isn’t really helpful.
