usb composite demo on kinetis k60

[prashantdev]

hi,

I am trying to use usb_cdc_msd composite demo from freescale usb stack 4.1. on k60n512vmd100 tower kit. My PC detects both storage and virtual com port. I'm able to access storage but when I try to open COM port it says "Port is being used by another application". I've windows 8.1 on my PC. I thought it was driver issue but when I ran  cdc_demo from example projects then virtual com port is working properly. Can someone help ??

Hi

Try the binary from http://www.utasker.com/kinetis/TWR-K60D100M.html#USB-MSD-CDC to see verify the operation and drivers.
If you continue having difficulties with the Freecale stack try the uTasker one, which allows a USB application to run on any Kinetis part with USB without needing to port between types.
It is free (see open source version) and includes K60 / USB simulation to make developing and study simpler and more efficient.

Mark

Thanx for the help but after flashing above binary file I didn't see any new device in device manager.

Hi

Is the green LED flashing at 2.5Hz, indicating the binary was correctly programmed and is running?
I tested on a Tower kit yesterday and its USB composite worked as expected (USB host connected to USB connector on SER board).

Hi Mark,

Green LED is not flashing. The bin file I flashed was meant for TWR-k60D100M but I am using TWR-k60n512. Will that file work on this also. I checked uTasker page in TWR-K60N512 demo there is no project for cdc - msd demo.

Hi

Please find attached a binary for the TWR-K60N512 (USB CDC MSD composite).

I built and simulated it but didn't verify on the HW (which I don't have present at the moment). The red LED blinks on this one.
Assuming it works as expected I will then put it on the TWR-K60N512 page (noting that the TWR-K60N512 is a very old board with K60N512Z part that has been superseded by the K60N512 revision 2 device)

Good luck

Regards

Mark

Thanx Mark for the help. The red LED was blinking but other than that there is no change.

Do you get a "ding" when you connect to the computer? If not the USB can't be connected.

If you get a "ding" you should see it in the device manager (even if there is a driver problem).

There are a few other binaries at http://www.utasker.com/kinetis/TWR-K60N512.html which also allow checking basic USB.

Mark

P.S. Make sure that the red LED flashes at 2.5Hz. There should be a 50MHz clock from the SER board that the K60 is using to generate its internal clocks form (including the 48Mz required for USB device). Ensure that this selection is correct.

Hi Mark,

Sorry for the delay in response. Your .bin file is working fine. Can u send me the whole project for codewarrior ??

[mjbcswitzerland]

Hi

The supported professional version is available on request at http://www.utasker.com/Licensing/request.html

If you only need the unsupported open source version I have added instructions and links below. The project includes projects for CodeWarrior, KDS, MCUXpresso, IAR, Keil, GCC, Rowley, CooCox, Green Hills, Visual Studio and so can be used cross-platform without restrictions.

Regards

Mark
