MQX for KSDK USB host fat system

[menkooldewurtel]

Hi,

with KDS2.0 and KSDK1.1.0 on FRDM-K64F Board: I want to write data  on a USB MSD with an FAT Filesystem.

I found this example: C:\Freescale\KSDK_1.1.0\usb\example\host\msd\msd_fatfs\sdk\kds\host_msd_fatfs_frdmk64f_mqx

Now want to copy the example and modify for my application. In the user Guide it is only described for iar, but i want to develop it in KDS2.0. So what i have to do to copy the example? I´ve found this Tool: Create new KSDK Projects but don´t know how to change the args when starting it for the fat-project. Can anyone help?`

Next problem will come up: Is it possible to add Components with PE to the project? Could be easier then to use the BM example?

Thanks for your help!

Hi Sol,

this manual shows only how to set up the MQX (lite) with PE, but for this it is very good. I´ve done this before, this was not the problem. In the example above, the FRDM board is used as an USB Host, I think this could be managed with the PE fsl_usb_framework of KSDK. At the moment i try to set up the parameters in PE to do the same as in the example. Init works fine. When i add a Device at the USB Port the ISR Callback is called.

In next step i will have to add the FAT fs to save data, is there an additional PE Component to manage these functions. When i try to understand the example, and copy it line by line there are many #includes i have to do, could be easier with PE funcitons ready to work...

Thank you and have a great day

Hi again,

i have migrated the example to PE and everything works. But there is one problem:

When i use the fsl_usb_framework of PE its generates a usb_host_config.h file in Generated_Code/SDK/usb/usb_core/host/include/usb_host_config.h

Another file is stored in SDK/usb/usb_core/host/sources/classes/common/usb_classes.c

In the second file (usb_classes.c)  is class_interface_map[]. With the defines in the headerfile (usb_config_host.h) i can enable components of the class interface map.

In the example (look at the first question), is there #define USBCFG_HOST_MSC (1). In the PE file not. If I add this by myself everything works. Where can i configure PE to do this for me?

I have added my PE-file, hope you can help?

Thanks
