I created a new device with the extension builder. (arduino board)
With mBlock PC, there is no problem, the connection and upload are OK.
But on Web version (with mLink), when I try to upload my program, the upload bar still at 0%.
No problem on the connection and processing code.
Any Idea ?
Thank in advance
[EDIT] : I made another simple test creating a new device (without library).
There is no problem. Maybe the problem can be caused by a device with many library ? (bigger file)
