Has anyone had success running the Freescale USB stack audio examples? .. If so what's your secret?
I'm using a Freedom KL25Z board, Freescale USB stack v4.1.1 and CodeWarrior 10.4
I have tried both USB_AUDIO_DEVICE_MKL25Z128_PEx and USB_AUDIO_DEVICE_MQX_Lite_MKL25Z128_PEx. They compile and load to the board but when I run them I get "This device cannot start. (Code 10)" in device manager. I have tried to uninstall reinstall drivers and modifying serial numbers to refresh the windows driver but nada! I have successfully run the Mouse example so the hardware is definitely working.
After wasting more time than I care to admit trying to get this project working on an XMEGA device I was really hoping the USB audio would just work on the Freedom board!
OK has anyone tried to use the audio example and not succeeded or is this just me? .... testing 123 is this thing on?
Comment out the low and high bytes audio controls in "usb_descriptor.c" file as below.
// AUDIO_BASS_CONTROL |
// AUDIO_MID_CONTROL |
// AUDIO_TREBLE_CONTROL |
// AUDIO_GRAPHIC_EQ_CONTROL |
// AUDIO_AUTOMATIC_GAIN_CONTROL |
// AUDIO_DELAY_CONTROL |
// AUDIO_BASS_BOOST_CONTROL |
// AUDIO_LOUDNESS_CONTROL |
I have tried to run the demo of USB_AUDIO_DEVICE_MKL25Z128_PEx and USB_AUDIO_DEVICE_MQX_Lite_MKL25Z128_PEx, but found the device with USB_AUDIO_DEVICE_MKL25Z128_PEx can not be recognized by the Host or as a unknown device, and USB_AUDIO_DEVICE_MQX_Lite_MKL25Z128_PEx can not pass the compiling, I have reported this to the USB stack design team, they told me it is a CW issue and we need to wait for the CW patch. Sorry for the inconvenience that has caused!!
