Can not compile example for VCP with STM32F429ZIT6

[bigbo]

Dear all,

Please help me with the following problem:

My MCU is STM32F429ZIT6 (Actually it is STM32F429DISCO board)
I made small test project for USB HID and the example from USB library is working fine.
To do this I made small "shield" and connected wires from PA11 to USB_OTG_FS_DM and PA12 to USB_OTG_FS_DP, both om them are through 22 Ohm resistors.
Also, USB pin D+ is pulled up to 3.3V with 1.5 kOhm resistor.

So, my laptop see the HID device, I can send and receive strings, also I put received strings to LCD2x16 which I installed before I try to use USB.
So I sure 100% my HID is working right.

Then, I want to make VCP connection because I have to send a huge information to laptop.
I found an example in USB library.
I made new project with right adjustments for my MCU, as it was with USB HID project.
I use VPC_Descriptor.mpas from the example. The file is included to the project in Project Inspector.
USB_Device_CDClass_STM32 and USB_Device_STM32_M4 are selected in Library Manager. Only these, because LCD is already disconnected.

When I try to compile the project I get many faults, they are shown below:

end.

Please help my to solve the problem.

Thank you for the support once again )

If there any possibility to know if buffer already sent?
Now I use delays between every 64 bytes buffer packet but it seems there is possible to send faster.

I found and use this - USBDev_RegisterDataSentHandler(@USBDev_CDCDataSent);
As I understud the procedure must have a variable, but how to use the variable?

Procedure USBDev_CDCDataSent(aVariable : Byte);
Begin
Sent:=True; // I use global variable here and checking after I send a buffer - While not Sent do;
End;

Is it right?
