Troubleshooting

Problem

Errors are observed while performing the --device-list command with MiniProg4 probe connected:

Error =  The HID read has timed out. Cannot open the 'MiniProg4 CMSIS-DAP HID-<serial-number> device.

Root cause

KitProg2 firmware is installed on MiniProg4.

Solution

Update KitProg-based device from Bootloader mode:

  1. Switch the KitProg3-based device to Bootloader mode.

    1. Unplug device while pressing the Mode Select button.
    2. Plug in device back.
    3. Release the Mode Select button.

  2. Perform firmware update using the --update-kp3 command .

Problem

The supported KitProg3-based device is connected and can be seen in the system, but it cannot be detected by the fw-loader tool.

Root cause

The device is currently accessed by another process (such as PSOC™ Programmer, etc.), or the fw-loader tool version is not up to date with the KitProg3 Firmware on the connected device.

Solution

Close any other applications that might use the connected KitProg3-based device and retry the operation. If the issue persists, make sure to use the latest version of the fw-loader tool, or downgrade the KitProg3 FW to the older supported version via firmware update from Bootloader mode (see steps above).
