hostapp_cces.exe does not work for vision analytical toolbox VAT-File-IO(609)

Hello,

I read the document Vision_Analytical_toolBox_UserGuide_Rel2.4.0.pdf to create example application VAT-File-IO(609) on CCES and follow the hardware setup are as the document required. To run the demo:

(1) build and run the application

(2) on windows cmd, change to the utils directory, and execute

hostapp_cces -a

the output is:

Total 1 Blackfin USB Device found

Device 0: WINUSB Blackfin USB Device.

(3) when execute hostapp_cces.exe -v or someother -f or else,

the output is:

Error WRITING usbcb for QUERY FIRMWARE

The current firmware does not support the -v switch.

(4) when execute hostapp_cces.exe -u,

the output is nothing! (After a long time,  there is still nothing  in window cmd,even no feedbacks!)

There are nothing in the output folder Media\IPTBX\output

The environment are: Windows 10, CCES 2.1.0
