Firmware update (change to USB Boot Mode by software?)
I have configured the Boot Mode to "SPI, USB on failure". If i want to update the firmware, i have to change the configuration on the PMODE pins to "USB" boot. I'm now asking myself if there is a possibility to download the firmware without changing the PMODE pins? I mean for developemnt it's not a problem. But if we deliver the device and the customer should set some jumpers or press a button to make a firmware update, this wouldn't be very nice. Can we do something by software?
