Check the JTAG chain connectivity on the target board and that the target board is powered on.

Click OK to continue.

Click Determine TCK Speed button to determine the maximum attainable TCK rate, in

KHz.

Click Detect IDCODEs to display the IDCODEs of CAPS-supported devices in the JTAG

chain. For unsupported devices, the string “Non-ST device” is displayed. If the detection

passes, the detected IDCODEs are listed in the dialog shown in Figure 41.: Detected

JTAG IDCODEs dialog.

If the detection fails, the dialog shown in Figure 42.: JTAG IDCODEs detection error dialog

displays. Check the JTAG chain connectivity on the target board and that the target board

is powered on. Click OK to continue.

Chaining multiple devices

This section describes procedures for specifying chained devices and their order. Refer to the

other subsections of 3.7: Validating and programming the target device for operations common

to both single and multiple devices.

If Multiple device view is selected, the program displays Figure 43.: Programming dialog for

multiple devices when the Program Device button is clicked. The multiple device view adds

dialog for chaining devices to the single device dialog.
