Daisy-chain on primary JTAG, USB Trace32 for qualcomm msm8x55

3 To operate properly in a dual-processor environment, Trace32 requires a special configuration
4 file and startup script. There must be a different set of these files for each processor. The files are
5 also dependent on the JTAG configuration. Example files are included in the AMSS release, in
6 the directory AMSS\products\<asic>\tools\t32.
7 By default, the Trace32 configuration file config.t32 is located in the Trace32 install directory.
8 The default startup script is t32.cmm and is also located in the same directory. For this
9 description, it is assumed that the Trace32 install directory is C:\T32.
10 Perform the following steps to install Trace32 and Qualcomm hardware support:
11 1. Follow vendor instructions to install Trace32 software to the Windows host.
12 2. Copy all of the files from the AMSS\products\<asic>\tools\T32 directory to C:\T32.

The MSM7x30 shortcuts include the following:

6 The Modem JTAG and Applications processor JTAG can be set up in the following
7 configurations:
8 􀂄 Daisy-chain Modem and Applications processor on primary JTAG – In this configuration,
9 the Modem and Applications processor JTAG tap controllers are internally daisy-chained
10 and appear on the primary JTAG port. In this configuration, the following equipment is
11 required:
12 􀂅 LA-7699 Power Debug II ETH
13 􀂅 LA-7742 JTAG ARM9™ with the following license extensions:
14 – LA-7765X JTAG Debugger Extension for ARM11
15 – LA-7843X JTAG Debugger Extension for Cortex
16 􀂄 Primary Modem JTAG and auxiliary Applications processor JTAG – In this configuration,
17 the Modem JTAG tap controller appears on the primary JTAG port, and the Applications
18 processor appears on the auxiliary JTAG port. The following additional equipment is
19 required:
20 􀂅 LA-7699 Power Debug II ETH
21 􀂅 LA-7705 Debug ETH
22 􀂅 LA-7742 JTAG ARM9 with the following license extension:
23 – LA-7843X JTAG Debugger Extension for Cortex
24 􀂅 LA-7765 JTAG ARM11
25 NOTE: In the primary Modem JTAG and auxiliary Applications processor JTAG configuration, the
26 auxiliary JTAG port pins are the GPIO pins, whereas the primary port has dedicated pins.
