AN4368SW and TWR-K60D100M

[JohnMusselman]

Hi,

I compiled AN4368SW_CW10.2 (using CW10.4) with no errors.  I loaded it onto the TWR-K60D100M-KIT hardware.  With a serial port connected to the tower, I get text at reset indicating the tower is waiting for a USB memory stick to be attached.  But attaching a memory stick elicits no response.

My local Arrow rep tried the same thing and reports the same results.

AN4368 was developed on the TWR-K60N512-KIT.  Has anyone made it work on the newer hardware or does it need to be updated?

Thanks,

John

Hi Alejandro and Monica,

It appears the short answer is that AN4368SW_CW10.2 does not work with current hardware/silicon.  Hopefully Freescale can make the necessary updates.

Thanks for sharing and reporting this, John.

We'll be checking on that.

John,

I was able to run the MSD_HS example of the USB stack in PE for the TWR-K60D100M.

This example can be very helpful. As you can see we only need the FS, the loader and the flash routines; files that are found in the bootloader.

I hope this helps,

Alejandro

Hi John,

I have delved into this and it seems this application note has not been migrated to the newer silicon revision.

My humble suggestion is the next:

As you can notice, the application note uses the USB stack. Then I would migrate first an example of the USB stack for this TWR system.

And then use the application files like the Loader.c and main.c.

Of course this is not an easy task because there has been changes  between silicon revision of the TWR-K60N512 and TWR-K60D100M.

I am going to try to get an example of the USB stack for new silicon rev.

Regards,

Alejandro
