FX2 - Firmware download

I have just started using a FX2 device.
When the linux machine boots up (with USB device already attached) or when the USB device is plugged into a running Linux machine, then the device enumerates as a default device and then downloads the firmware from the linux machine and then renumerates.

I want to know, if there is a way to download the firmware again, without disconnecting and then re-connecting the device?

Also after power-loss, when the linux machine boots up, this enumeration/renumeration process somehow wouldn't work, evn though the device is detected. Can somebody explain why it is so and how to get around it without disconnecting and then re-connecting the device?

  • Yes, you can always load a new firmware into any of the Cypress usb devices. The download request is implemented in the usbcore.
    The device will be recognized when you are doing the Enum call in the firmware.
    For more information you should take a look into the datasheets.
