Flicker Flicker RVI v4.0 supports the SWD debugging protocol as an alternative to JTAG. SWD can only be used with the LVDS probe, and without using the JTAG ribbon cable. The probe must be a v2 type as described, and you might have to upgrade its firmware. - Page 20 The v2 LVDS probe is supplied as standard with RVI v3.1 and later units. The probe can also be used with a RVI v3.0 unit, if you update it with a firmware patch that provides support for the v3.1 probe.

The BUS LED indicates module initialization and RVI expansion bus power. It lights up when RVI is initializing the RVT unit, and remains lit while the RVI expansion bus is powered. The BUS LED flashes on a module connected to RVI through the expansion bus if an error is detected in trying either to identify the module or to provide power to it. -

To connect the RVI run control unit to your host computer and to the target hardware: Ensure the RVI software is installed on the host computer. Connect the host computer to the RVI run control unit, using either the USB port or an Ethernet connection, as required. The following figure shows connections using both the... - Page 30 You have only to do the network configuration once. If the RVI unit is powered up with only a USB connection, it uses an IP address of 127.0.0.0. However, if a network cable is also attached, the IP address associated with the USB connection is the IP address that you have assigned to the RVI unit, or that it obtains from a Dynamic Host Configuration Protocol (DHCP) server.

Ensure that the RVI unit is disconnected from the power supply and from the target board. Warning Failure to remove the power from the RVI unit before connecting it to the RVT unit can cause damage to the hardware and/or personal injury. - Page 35 Figure 3-3 Profile view of connected units Clip the plastic ventilation grill that you removed from the RVI unit onto the top of the RVT unit. For up to 16-bit trace port widths, connect one end of the interface cable to the 60-way trace probe connector of the RVT unit, and the other end of the cable to the trace probe.
