Hi,
About MCAN, I tried to porting MCAN driver to mmw demo. (refernece source code: mcu_plus_sdk_am273x_08_02_00_26\examples\drivers\mcan)
When MCAN transmit is running, it always hang at "SemaphoreP_pend(&gMcanTxDoneSem, SystemP_WAIT_FOREVER);" to wait for Tx completion.
I think MCAN ISR may not work.
Is there anything else to check?
Thanks.

=========================
void App_mcanInit(void)
{
int32_t status = SystemP_SUCCESS;
HwiP_Params hwiPrms;
/* Construct Tx/Rx Semaphore objects */
status = SemaphoreP_constructBinary(&gMcanTxDoneSem, 0);
DebugP_assert(SystemP_SUCCESS == status);
status = SemaphoreP_constructBinary(&gMcanRxDoneSem, 0);
DebugP_assert(SystemP_SUCCESS == status);
/* Register interrupt */
HwiP_Params_init(&hwiPrms);
hwiPrms.intNum = APP_MCAN_INTR_NUM;
hwiPrms.callback = &App_mcanIntrISR;
status = HwiP_construct(&gMcanHwiObject, &hwiPrms);
DebugP_assert(status == SystemP_SUCCESS);
/* Assign MCAN instance address */
gMcanBaseAddr = (uint32_t) AddrTranslateP_getLocalAddr(APP_MCAN_BASE_ADDR);
/* Configure MCAN module */
App_mcanConfig();
/* Enable Interrupts */
App_mcanEnableIntr();
}
