Hi,
I'm using the FX2LP dev kit and I'm trying to get the FX2LP to load my firmware from EEPROM. My hex file, when transferred into RAM, works fine. When I write the IIC file to the EEPROM and then reset the device with the reset button, the firmware initialization seems to execute properly, but as soon as I try to make any USB requests they all fail.
Again, it seems like the firmware is loading and executing the initialization properly because it comes up with my VID/PID and turns on the LEDs that I've programmed, but the USB requests fail.
Any suggestions?
Thanks,
Andrew

Hi Mallika,
Going back through my code I see that the IIC that I was uploading was corrupted; fixing the IIC file fixed my problem.
Thanks,

Hi Andrew,
Kindly provide more details as follows:
>> Which firmware are you loading? Is it custom firmware? If yes, could you please check with the FX2LP kit default firmware also?
>> Which FX2LP kit are you using?
>> Which host application are you using and which USB requests are failing? Please share USB Analyzer/Wireshark traces.
Regards,
Mallika
