Home Forums Sparkfun MP3 Shield Library Support Forum FilePlayer.ino Compiles but will not upload Reply To: FilePlayer.ino Compiles but will not upload



The symptom as described is a bit odd and not really coherent. The issue is that down loading has really nothing to do with compiling. I don’t have a Uno at hand this moment, to completely verify your statement.

However, something does come to mind; The more recent versions of SdFat Lib have deprecated a command used in the FilePlayer.ino, and such will fail to compile. The SFEMP3 repo has 20131225 inside it, which will compile.

Is it possible that your compile/verify environment is not the same as your compile/upload?

I may be able to find an Uno later today.


I would mention that I have never seen “<em style=”margin: 0px; padding: 0px; border: 0px; outline: 0px; font-size: 13px; vertical-align: baseline; color: #9e9e9e; font-family: Arial; line-height: 19px; background: #fbfbfb;”>avrdude: stk500_recv(): programmer is not responding<span style=”line-height: 1.5;”>”  as a result of source code. Rather the AVRDUDE not finding the serial port. Under File/Preferences check the Show Verbose output during compile and upload. You will likely see the debug of Avrdude sending out the poll messages. </span>

One thing can be that the Serial Port is busy or already in use. Another parent instance of Arduino may have it. Note that children from the same instance share it. But if the IDE is ran a 2nd time this can readily happen.
