If eKnitterFlash cannot see eKnitter

If the flash tool cannot find eKnitter, the most common reasons are a missing USB driver, the wrong cable, a charging-only cable, or a USB connection that was not detected correctly.

Install the driver Install the Silicon Labs USB to UART driver if your computer does not recognise the eKnitter board.
Use the correct cable Use Micro USB for KH 910 and USB-C for KH 930 / KH 940. Make sure it is a data cable.
Try another USB port Connect eKnitter directly to the laptop if possible. Avoid USB hubs or adapters while updating.

If the cable is not connected correctly.

If the USB cable is not connected correctly, or your computer cannot see the eKnitter board, eKnitterFlash will show a message like this.

  • Install the Silicon Labs USB to UART driver if needed.
  • Use the correct USB data cable: Micro USB for KH 910, USB-C for KH 930 / KH 940.
  • Make sure you are not using a charging-only cable.
  • Unplug the USB cable, wait a moment, and plug it in again.
