PIC32 USB CDC No function after last update

Hello together

When the driver is in place, Win 10, 7 and XP recognise it as a Flowcode USB Serial device. The driver is installed and then works normally.

At the moment I can compile in FC9 and 10 without errors but no operating system recognises the device. I get the message Unknown device and error when requesting a device description.

Hello together

I have noticed
in FC 9 I can recompile software I wrote before the update and the USB port works.
i can change the software, compile it and usb works. if i write something new usb does not work.

it would be nice if someone would take care of this for once

Please post your working project (FCFX, C and driver files) and also a new project which does not work (again, FCFX, C and driver files) and we will try to discover the problem.

Hello Steve

Here is my data from FC9
Where can I find the driver or the batch file?

[SpeedPIC32]

here these do not work.

Replace txt with bat

[SpeedPIC32]

$(compilerpic32)batch\PIC32compCDC.bat
"$(chip)" "$(srcdir)" "$(target)" "$(family)"

Thanks for the files.

I've compared both files and these are the differences between the 2 projects:

• Config settings for the chip are very different
• The old one uses a delay which clears the watchdog automatically

Both of these issues could be causing your issues. Please check the chip config settings are correct for the new project. And also make sure "Auto clear watchdog" is ticked in the "Project Options" window.

Hello all
Steve Matrix was right.
It just didn't work with the alignment of the data anyway.
Now I had a good idea.
I took over the compiler options from version FC9 and now it works again.
Here is my data

Compiler location
$(compilerpic32)batch\PIC32compCDC.bat
Parameter
"$(chip)" "$(srcdir)" "$(target)" "$(family)"

Linker / assembler location
$(compilerpic32)bin\xc32-bin2hex.exe
Parameter
"$(srcdir)$(target).elf"

Programmer location
$(mplabxdir)mplab_platform\mplab_ipe\ipecmd.exe
Parameters
/P$(chip) /F"$(outdir)$(target).hex" /TPPK4 /M /OL

File Viewer Location
C:\Windows\Notepad.exe
Parameters
$(outdir)$(target).c


I hope it helps one or the other.
