This section describes the troubleshooting steps for the instances where the
MCU is installed on a target system and the RKICS is used to interact with the
target system through the MON08 cable. These instances include in-circuit
simulation/emulation and FLASH memory programming through the MON08
cable.
1. Disconnect the target system and make sure that the RKICS operates
correctly when configured as described in the start up instructions. See
2.4 Installing the Hardware and B.4 Troubleshooting the Start Up.
2. If the start up works, the RKICS should be functioning well enough to
place the MCU on the target system into monitor mode.
3. Prepare the RKICS for use with the MON08 cable. Turn off the power to
the target system. Exit the RKICS software. Remove the power plug
from the RKICS. Remove any MCU from sockets XU1, XU2, and XU3.
Install a jumper on W5 unless the target system is using a 4.9152-MHz
oscillator. Jumper selections on W1 and W3 have no effect when using
the MON08 cable. Install a jumper on W2 pins 2 and 3.
4. Connect the 16-pin cable from J6 on the RKICS to the target system's
MON08 connector. Details on designing a MON08 connector for the
target system are given in Table 4-1. MON08 Target System
Connector P1. If cutable jumpers were used on the target board, the
jumpers must be cut before using the MON08 cable.
5. The target system (including the MCU) must be externally powered. The
target system's MCU V
RKICS to communicate with the RKICS. Do not apply power to the
target system at this time.
6. Exit any ICS08RKZ software that may be running on the host PC.
Connect the serial cable between the host PC and the RKICS. Apply
power to the RKICS by connecting the wall adapter's output jack to the
RKICS. At this point, the ICS power LED should be lit, and the MCU
power LED should be off. If the MCU power LED is on, there may be a
problem with the host PC's serial port or the serial cable. Refer to step 9
for information on host communications.
