Part Number: TMS320F28075

Hello Champs,

Customer's own F28075 board USB (used as Device Mode) can successfully run in Windows7 64-bit system.

In Windows7 32-bit system, USB driver can be installed successfully but it displayed that the USB cannot work properly.

Would you please kindly help? Thanks!

I believe our windows drivers are signed for a 64-bit machine.

You may be able to work around this in the OS. I recommend searching the internet for some possible solutions or work-arounds. Otherwise, you should use the 64-bit Windows machine.

Hello Sal,

The issue has been solved after changing the USB FIFO size value back to 64 as same as that of in our example codes "USB_DEV_BULK".

If it is modified to 256, USB can run successfully in Windows7 64-bit system but cannot run in Windows7 32-bit system.

Would you please kindly help? Is it possible that we can release two different driver versions for 32-bit and 64-bit system separately?

Thanks!

Best Regards,
Linda
