I am using the SAM3S1B processor. I want to use the ROM bootloader communicating via the USB port. To enter the bootload mode from my application I clear the GPNVM bit 1 and then reset the processor with a software reset. No other action is taken. The device appears to go into the boot mode. However, I cannot communicate and when I check the enumeration using USB View I see that it has not enumerated. Is there something I'm not doing? Any ideas out there? Thanks.
The problem I have is that interrupt routine is called always one more time after the pin is driven high. I have a picture which shows the problem but I cannot attach it for some reason... I can send it to anyone interested
