VxWorks 5.5 BSP Developer’s Guide The third test spawns a single pkLoopbackTest( ) task for each serial port connected in loopback mode. Each port sees a pattern of sequential characters sent and received at the maximum baud rate. All characters must be received in the order sent. If this test fails, check that all serial ports under test are set up correctly for loopback mode. Make sure that the serial driver is handling receive and transmit interrupts properly. Make sure that all serial channels under test have been configured and initialized to the correct values. The fourth test spawns several pkLoopbackTest( ) tasks for each serial port connected in loopback mode. Each task repeatedly sends a particular character to one of the ports. There are several tasks for each serial port under test. Each port should receive all the characters that were sent. If this test fails, check the same problem areas suggested for the third test. The third and fourth tests spawn one or more pkLoopbackTest( ) tasks for each serial device connected in loopback mode. These tasks run concurrently, sending and receiving characters at the highest baud rate supported by both host and target. It is possible that target boards with slower CPUs and many serial devices might not possess the raw processing power required to keep up with the tests. If hardware limitations are causing the loopback tests to fail, the tests can be configured to lighten the processor load. The serial.tcl tests run at the highest baud specified in the bspVal macro, BSPTEST_HOST_RATES (provided that the rate is supported by both the host and target). Modifying BSPTEST_HOST_RATES to exclude the higher common baud rates will cause the tests to run at a lower rate, thus avoiding possible hardware- related problems. Additionally, the pkLib.c constant PK_LOOP_TASK_NUM can be changed from the default value of 4 to decrease the number of concurrent tasks running in the fourth test. In this case, the object code file pkLib.o must be rebuilt from the changed pkLib.c source file. Target boards with several serial devices and a small amount of local RAM (1Mbyte or under) might run out of memory while executing the tests. In this case, either configure the target to use an external memory card or decrease the number of tasks running as described above. If the test script execution ends prematurely, the target board might be left set to a baud rate other than T1_TIP_BAUD. This situation could leave the board in such a state that a power cycle reset would be necessary to continue with other tests. Barring serious hardware or software limitations (such as an identifiable VxWorks problem), the target board must pass all tests for the BSP to be validated. CONFIGURATION PARAMETERS BSPTEST_HOST_RATES Baud rates supported on host. (required) T1_SER_DEVICE Serial device to be used on host. (required) 396

The entire test takes approximately 7-10 minutes to run. See bspVal.sh for an explanation of options. The tests within this script connect a routine to the system clock interrupt handler using the sysClkConnect( ) routine, which uses the sysClkRoutine function pointer variable. This call to sysClkConnect( ) for sysClkRoutine disconnects any routine the BSP might have previously connected as the system clock ISR. NOTE: This reference entry lists the most likely reasons for a test’s failure. However, it does not list all possible reasons. Tests one through four check the accuracy of the system clock at several frequencies: an optional extra rate, minimum, maximum, and the default rate, respectively. To measure the rate of the system clock, a simple callback routine is connected to the system clock ISR using sysClkConnect( ). This callback routine increments a counter on every clock tick. J 397
