Hi,
I am using nxpUSBlib for using LPC1768 as host reading the memory sticks. I am using CooCox as the compiler/ linker development environment. It took some time to port nxpUsblib to CooCox.
Some how after porting - I do not see nothing happens
1. MassStorageHost_Task(); - This always returns, as "if (USB_HostState[FlashDisk_MS_Interface.Config.PortNumber] != HOST_STATE_Configured)" fails. Always, I get USB_HostState[FlashDisk_MS_Interface.Config.PortNumber as 0 and HOST_STATE_Configured as 11.
2. MS_Host_USBTask(&FlashDisk_MS_Interface); This seems to be just a variable - (void)MSInterfaceInfo
3. USB_USBTask(); Also comes out.
4. Some how I do not see "USB_IRQHandler" getting called. Seems some thing missed in configuration..
5. Is there any step step guide (or note) which I can refer to find if the configuration is correct and isolate the problem?
With best regards,
Phani.
