USB K22 flash

Hi,

I'm sending some data via USB on MK22FN512 by:

 

USB_DeviceSendRequest(handle, ep, buffer, length);

 

If buffer is pointing to chip's flash area then the other doesn't receive correct data. If I move buffer to SRAM, then correct data passes through.

 

Is there anything I have to do to be able to send data from flash via USB?
