I am testing X-NUCLEO-CCA02M1+NUCLEO-F401RE by following below instruction (page 7-9).
After that instruction, X-NUCLEO-CCA02M1+NUCLEO-F401RE should be recognized as
"STM32 AUDIO Streaming in FS Mode" in device manager of windows7 PC,
but not shown. Only virtual COM port is show in device manager.
I have tried below.
1. I followed another instruction on youtube, but I got the same result.
2. I build below firmware and debug it with system workbench
But connect/disconnect callback functions are never fired when I connect/disconnect USB mini cable on X-NUCLEO-CCA02M1.
(I have set the breakpoints at HAL_PCD_ConnectCallback and HAL_PCD_DisconnectCallback in usbd_conf_f4.c)
Does anybody success to use as sound device on PC with the combination of X-NUCLEO-CCA02M1+NUCLEO-F401RE?
I also found similar question in this forum, but nobody answer...
I hope some hints or success information.
I have switched to the combination X-NUCLEO-CCA02M1+NUCLEO-F476RG and it works perfecty.
I just followed to the above same instruction with re-soldering resiter at SBx pads.
If you success with F401RE, please inform to this thread.
I don't want to throw away my F401RE...
I have bought new NUCLEO-F401RE.
It works perfectly with X-NUCLEO-CCA02M1.
I compared the old NUCLEO-F401RE and new one, there is the difference of revision.
Old one is MB1136 C-01, the new one is MB1136 C-04.
I think some electric condition is difference.
But I could not found the documentation about revision of 401RE.
I give up!
Anyway, please check your revision if you encounter the same problem in future.
