How can I fix the Error of MSC Bootloader with ATxmega32a4? - avr

Question

I'm trying to upload a .hex file via Uart into an ATxmega32a4. I'm using BASCOM IDE and Programmed my MCU with the sample code which is available in sample folder of Bascom (I have attached my code). So I'm using MSC Bootloader Wizard in Bascom to upload my code but unfortunately it has error 6006. I increased timeout but the problem is not fixed.
I monitored serial port as you can find it in attachments.
Could anyone help?
