Developing a USB memory stick Data Logger with Processor Expert and USB baremetal stack v. 4.1

Hello,

 

I need a Data Logger in a USB memory stick in my application using MK70. As my project was initialized with Processor Expert in CodeWarrior  and I didn't find a reference example with Processor Expert in Freescale USB Baremetal Stack, I tried to copy the files from K70 MSD-FAT example located at "C:\Freescale\Freescale USB Stack v4.1.1\Source \Host\ examples\ msd_mfs_generic\ cw10\ kinetis_k70", except for vectors.c and K70 registers initialization files, since Processor Expert already initializes interrupt vectors and includes "IO_Map.h" file, which defines the addresing and macros of all the registers in the MCU.

 

After a lot of work, copying all the files and include their respective paths into Compiler Settings, I got some build errors. In the beggining, those errors were due to the lack of some header files. But now, I got some errors that I don't understand the cause:

 

 

Maybe somebody can give me an idea of how to do it in a easier way with less work and avoiding these conflicts and errors. Or if I don't find another way, I will have to create a new project based on that demo (without PE) (following the instructions from USBHOSTUG.pdf) and copy what it is already initialized and done with Processor Expert.

 

 

Thanks,
