Hi to all, now I'm developing with K20 (MK20DN512VLL10 in LQFP 100-pin package) before i developed wit FRDM-K64
I heared that on K20 the USB stack will not be update and developed only with KSDK (for uP where KSDK is available).
What I want to do is the Firmware Update via USB flash drive. I have already do in some other application VIA SERIAL (RS232) MODE. What I never did in my past is usa an USB stack.
I have imported, with processor expert, the component "USB_LDD" , i try to add some other component (FSL_USB_MSD_host, FSL_USB_Mouse, FSL_USB_Keyboard, FSL_USB_CDC, USB_Host_CMX, USB_HID_CMX, USB_Config_CMX) but no one seems to be the correct.
What I need is something that allow my firmware to dected if a Memory-Stick is connected and route inside his memory. (The transfer of data is another big progress and I need FileSystem and many other thing, for now I only want transfer small byte for example!)
Example: I want that the firmware give an event (like timer event in file Events.c) when a memory stick is connected and he can access to the file located in a folder like this "H:\ExampleFolder\ExampleFile.hex" and transfer the first 100 byte
What I must to do? i do not find no-one processr expert method that allow me to do this in USB_LDD and I not find example for my specific uP or other smilar uP that use ProcessorExpert components...!!!
