Using the usb_dev_serial example under SysBios

Other Parts Discussed in Thread: SYSBIOS

Hello,

I've been trying to use the example usb_dev_serial under SysBios with no luck. Here's what I did so far:

1. SysBios takes care to the AINTC initializations - So I removed these.

2. Added --gcc to the compilation flags to support __attribute__ (packed)

3. I have no screen, so I removed all the screen related code as well.

4. I also removed the UART and `loopbacked` the data (that I tested without SysBios as well).

The situation now - The device connects and registers as a COM in Windows 7. But when I try to open it - It always fails.

Did some digging, and found out that the HandleRequests function under usbdcdc.c is never called, meaning I'm missing a fair deal of the interrupts.

What did I miss? Why are these interrupts missed?

Any help will be appreciated - Especially tips on how to debug this. (I'm fairly new to TI embedded environment)

Thanks

Nitay
