Hi guys, i`ve spent several hours trying to figure whats wrong in my initialization routine, but no luck at all...
Here is my code
#include ''system_stm32f4xx.c''
#include ''stm32f4xx.h''
#include ''usbd_cdc_core.h''
#include ''usbd_cdc.h''
#include ''usbd_usr.h''
#include ''usbd_desc.h''
#ifdef USB_OTG_HS_INTERNAL_DMA_ENABLED
#if defined ( __ICCARM__ ) /*!< IAR Compiler */
#pragma data_alignment = 4
#endif
#endif /* USB_OTG_HS_INTERNAL_DMA_ENABLED */
__ALIGN_BEGIN USB_OTG_CORE_HANDLE USB_OTG_dev __ALIGN_END;
void main() {
SystemInit();
USBD_Init(&USB_OTG_dev,
USB_OTG_FS_CORE_ID,
&USR_desc,
&USBD_CDC_cb,
&USR_cb);
}
Beside the files included in the project above there is nothing else included, only what you see.
My problem is that the complier reports me with errors saying :
Building configuration: imu - Debug
Updating build tree...
main.cpp
Linking
Error[Li005]: no definition for ''USBD_Init'' [referenced from C:\Users\Bogdan\Desktop\discovery F4\IMU Project\Debug\Obj\main.o]

Error while running Linker
Total number of errors: 4
Total number of warnings: 0
My question is where are these variabile defined? i tryied several projects from internet, and on all variants i get to this point.
Why is it saying that are not defined?
When i try to complie the code, it complies, but when i try to build/burn to the board it reports me thouse errors.
This is my first time i try to play with usb libs...
thanks
