USB Enumeration Failed When FW Size is > 8k

Hi all,

I'm using CY7C68013A-100 chip sets that has 16k of on chip memory. However, when my firmware code is more than 8k, the enumeration process fails. Has anyone run into this kind of issue before?

I've tried playing around with the project options from uVision without much luck....

Thanks,
Peter

  • Yes, I did recompiled the driver code using the build command. I need to determine:

    1. Is this a Cypress driver code issue?
    2. Is this a configuration issue with the way I configured my Keil uVision 3.0 project settings (ie. the data and code space ranges)
    3. Is this a C51 library issue?
    4. Something to do with my firmware. I don't think it's my code, but it could be the the framework code that I'm using. Normally I don't need to look into the framework code because it used to work for my older chipset...
