Hye,
Without answer I allow myself to post again my previous question about USB Developer Kit for STR9.
I have tried many possibilities but I can't see where is the problem.
The demo is always blocked at the same line:
while(pInformation->Current_Configuration == 0)NOP_Process();
Could you kind enough to tell me where is the problem?
Best regards,
Francois

Hi fustinfrancois,
Sorry for the late!!!
Could you please give me more details regarding your software/hardware and tool chain environment?
Are you using the ST Eval board? What is your tool chain? Are you using the USB Developer kit without modification?
With Best Regards
AnisAS

Hye,
Like I said in my previous post, my eval board is a HITEX STR912. I have Tanto Base module for JTAG Debug. The development tool is HITOP v3.5 and my operating system is Vista 32bits.
In first step, I use USB developer kit without modification. After I've tried a lot of configurations and changes but without success. I don't know why it doesn't work. It seems there is not USB activity on board when I plug the cable on PC side (except the led switch on because it is directly connected to the VBUS).

Im using STM32, but the line:
while(pInformation->Current_Configuration == 0)NOP_Process();
Is where the device waits to be enumerated by the PC. If that does not happen it will not move past this spot.
Does it work if you do the following:
1. Remove power to demo board
2. Remove USB from your Demo board
3. Add power to demo board
4. Plug USB into Demo board again.
Sometimes when Just firing up from Software Reset enumeration do not take place correctly. Even if you unplug and replug the device.
I blame windows
