USB host, Int Flash Release problem

Hi,

CW 7.1.2, MQX 3.4, M52259EVB

My USB host application is working fine in Debug Mode but there is a problem in Int Flash Release mode.

Every time when I insert the USB stick I got this error:

************************************************************************
Vendor Information: Mass Storage Device
Product Identification: Flash Disk
Product Revision Level: 8.07
************************************************************************
Error while opening partition (UNKNOWN ERROR !!!)
Device removed, starting device cleanup
--->Closing MFS
--->Uninstalling
--->Uninstalling PM
--->Closing disk

After that I have to restart microcontroller to use USB again.

I've check my application, web_hvac and mfs_usb examples with freescale and kingston sticks so far.

Any ideas?

Regards,

tomaszk

Hello,

this is known bug of CodeWarrior compiler. I recommend to use CW7.2.
