Error after choosing USB communication with STM32CubeMX

[electronicsbasickid]

Hi,

I'm using a STM32L100RC discovery board for a project. I'm trying to communicate with the USB port (Communication Device Class). After configuring the USB and USB_DEVICE part with STM32CubeMX, I have the following errors on Keil : 

.\Objects\Keil_TEST.axf: Error: L6218E: Undefined symbol hpcd_USB_FS (referred from stm32l1xx_it.o).

Not enough information to list image symbols.

Not enough information to list load addresses in the image map.

Finished: 2 information, 0 warning and 2 error messages."

I tried to add "extern PCD_HandleTypeDef hpcd_USB_FS;" in the file stm32l1xx_it.c. and the header "usbd_conf.h" but it still doesn't work.

Does anyone know how to solve this issue? 

Thank you in advance,

Jay.

Hi @electronicsbasickid​ ,

Sorry for the delay.

I'm not able to reproduce this issue , can you please share your ioc?

Which CubeMX version are you using?

Recreating a new project from the beginning cleared the errors.

Hi @electronicsbasickid​ 

If I well understand , you don't have anymore the issue when you start project from scratch?

Nice to hear this :) .

Houda

[electronicsbasickid]

yes, exactly.
