46-pin RH850 Aurora target pinout
Signal Direction is described from the BlueBox perspective.
Jumper
Target debug connector provides a watchdog disable signal. A target can implement watchdog disable function through this pin for more predictable debugging of the target application. Sometimes it’s even impossible to debug the target application without disabling the embedded target watchdog logic. When the BlueBox debugger connects to the CPU through the target debug connector, it forces low or high (depending on the J1 setting) level to the watchdog disable signal, which then yields disabling watchdog logic in the target (when supported by the target).
A jumper is present on the adapter which connects high level (Vref voltage) or low level (GND). Jumper position 1 is marked with a white line.
Jumper position 2 (Default): Not connected
Jumper position 1-2: VREF – WDGDIS
Jumper position 2-3: WDGDIS – GND

Make sure this adapter fits on your target connector - check Cross Table. |
