CCSv3.3 SR12 Simulation Errata

Problem - CCS hangs on asynchronous run in Multicore Simulator

In CCSv3.3 SR12, on using C64x+ multi-core simulator configurations (TCI6486, TCI6487, TCI6488, & C6474), CCS could hang while performing asynchronous run on one or more of the cores, if the code is in external memory. [Asynchronous Run: Running individual cores from the respective core's CCS window]

List of Simulator Configurations that have this problem:

• TCI6486 Simulator, Big Endian

• TCI6486 Simulator, Little Endian

• TCI6487 Simulator (Asymmetric L2), Big Endian

• TCI6487 Simulator (Asymmetric L2), Little Endian

• TCI6487 Simulator (Symmetric L2), Big Endian

• TCI6487 Simulator (Symmetric L2), Little Endian

• TCI6488 Simulator (Asymmetric L2), Big Endian

• TCI6488 Simulator (Asymmetric L2), Little Endian

• TCI6488 Simulator (Symmetric L2), Big Endian

• TCI6488 Simulator (Symmetric L2), Little Endian

• C6474 Simulator (Asymmetric L2), Big Endian

• C6474 Simulator (Asymmetric L2), Little Endian

• C6474 Simulator (Symmetric L2), Big Endian

• C6474 Simulator (Symmetric L2), Little Endian

Workaround

To get the work around follow the procedure given below.

Steps

1. Download the errata zip file - SR12_errata.zip
2. Extract the contents of the zip file to "drivers" directory.
   1. Drivers directory is located in your CCSv3.3 SR12 Installation [<CCS_Installation_Directory>\drivers]
   2. In the CCS setup, replace the configure file for every core of the target DSP with the extracted *.cfg files!
3. Launch CCS

The zip file contains the following configuration files (that contain the workaround for the problem) for the above simulators

• simtci6488_symmetric.cfg

• simtci6488_asymmetric.cfg

• simtci6487_symmetric.cfg

• simtci6487_asymmetric.cfg

• simtci6474_symmetric.cfg

• simtci6474_asymmetric.cfg

• simtci6486.cfg

• simtci6472.cfg

Problem - Emif.log file is generated while using Simulator

While running C6467 simulator emif.log file is getting generated in c:\ drive. This file will grow in huge size within few minutes. This file is a debug log which is enabled in the simulator configuration file.

Work Around

To avoid this issue follow the given step below.

• Open CCSetup
• Click on one of the CPUs, check what is the Simulator Config file on the right pane of CCSetup
• Open the simulator config file
• Search for "test_log_file" and comment that line. (comment syntax - //).

After this you shouldn't see emif.log getting generated.

Note: All the above issues mentioned here will be fixed in the subsequent release.
