TDA4VM: RTI RTI timer does not work.

我需要咨询相关工程师再给您回复。

感谢您的帮助。是的，更换12M时钟后可以连续进，但周期貌似不准确。

好的。

请将timer有关的配置贴出来。

我用的就是开发包里的例子： \ Ti processor SDK rtos-j721e-evm-08_ 00_ 00_ 12\ti-processor-sdk-rtos-j721e-evm-08_ 00_ 00_ 12\pdk_ jacinto_ 08_ 00_ 00_ 37 \ packages \ Ti \ CSL \ example \ RTI。部分代码如下：

void test_csl_rti_dwwd_test_app(void)
{
/* @description: Test that runs a basic functionality test of WDT

@requirements: PRSDK-5575

@cores: mpu1_0 */

#ifdef LINUX_HOST_PROC_WDT_CONFIG

Board_initCfg boardCfg;

boardCfg = BOARD_INIT_UART_STDIO;
Board_init(boardCfg);

/* Register Interrupt */
isrFlag = 0U;
if(RTIInterruptConfig(APP_RTI_MODULE) != 0)
{
RTIAppUtilsPrint("\r\nRTI Interrupt configuration failed. \r\n");
#ifdef UNITY_INCLUDE_CONFIG_H
TEST_FAIL();
#endif
return;
}
RTIAppUtilsPrint(APP_NAME ": RTI App WDT timeout interrupt configured.\n");
while (0U == isrFlag)
{
/* Wait for interrupt */
}
#else
uint32_t rtiModule, rtiWindow_size, rtiPreload_value, rtiReaction;
int32_t config_status;
#ifndef DISABLE_UART_PRINT
Board_initCfg boardCfg;

boardCfg = BOARD_INIT_PINMUX_CONFIG |
BOARD_INIT_UART_STDIO;
Board_init(boardCfg);
#endif
RTIAppUtilsPrint("\n Board init complete\n");

/* Register Interrupt */
isrFlag = 0U;
if(RTIInterruptConfig() != 0)
{
RTIAppUtilsPrint("\r\nRTI Interrupt configuration failed. \r\n");
#ifdef UNITY_INCLUDE_CONFIG_H
TEST_FAIL();
#endif
return;
}
RTIAppUtilsPrint("\n Interrupt config complete\n");

/* Configure RTI parameters */
rtiModule = RTI_APP_RTI_CFG_BASE;
rtiWindow_size = APP_RTI_DWWD_WINDOW_SIZE;
rtiReaction = APP_RTI_DWWD_REACTION;
rtiPreload_value = RTIGetPreloadValue((uint32_t) RTI_CLOCK_SOURCE_32KHZ,
(uint32_t) APP_RTI_DWWD_TIMEOUT_VALUE);

/* Select RTI module clock source */
RTISetClockSource((uint32_t) RTI_CLOCK_SOURCE_32KHZ);
config_status = RTIDwwdWindowConfig(rtiModule, rtiReaction,
rtiPreload_value,
rtiWindow_size);
if (config_status == CSL_EFAIL)
{
RTIAppUtilsPrint(APP_NAME ": Error during Window configuration.\n");
#ifdef UNITY_INCLUDE_CONFIG_H
TEST_FAIL();
#endif
}
else
{
RTIAppUtilsPrint(APP_NAME ": DWWD is configured for %u ms time-out \n",
APP_RTI_DWWD_TIMEOUT_VALUE);
RTIAppUtilsPrint(APP_NAME ": DWWD will generate interrupt after "
"above time-out period.\n");
RTIDwwdCounterEnable(rtiModule);
/* Let DWWD expire here */
RTIAppUtilsPrint(APP_NAME ": Wait for %u ms for interrupt "
"to be generated by DWWD.\n", APP_RTI_DWWD_TIMEOUT_VALUE);

while (0U == isrFlag)
{
/* Wait for interrupt */
}
RTIAppUtilsPrint(APP_NAME ": RTI App completed successfully.\n");
UART_printStatus("\n All tests have passed. \n");
#ifdef UNITY_INCLUDE_CONFIG_H
TEST_PASS();
#endif
}
#endif
}

好的，已经反馈给相关工程师。
