*Obsolete* 4.1i iMPACT - The V300 appears as an "Unknown Device" when I attempt an "Initialize Chain" operation


Keywords: V300, unknown, iMPACT

Urgency: Standard

General Description:
In 4.1i iMPACT when I perform an "Initialize Chain" operation on a JTAG chain that contains a V300 device, the V300 appears as an Unknown Device.


This problem will not prevent you from performing any JTAG operations on the device.

To proceed, you can assign the unknown device a V300 .bit file, and then perform any Program, IDCODE, or Verify operations as usual.

This problem was fixed in 4.2i iMPACT.
