Hi All,

Refer to DRA76x TRM there is no description about which interrupt is mapped to CAL_IRQ on IPU1/IPU2.

the IRQ_CROSSBAR_353 is CAL_IRQ, but there is no mapping in section IPU1_Cx_INTC/IPU2_Cx_INTC.

could you please help to guide me where can find these information.

Regards

Since this does not relate to TINA-TI, I have notified the right organization to have a look at this question for you.

Joe,

The CAL IRQ is not default mapped to any interrupt service on the IPUs. Please check the "IPU1_Cx_INTC Default Interrupt Mapping" table and write a simple code to map the CAL IRQ to a free IRQ service. This can be done by modifying the values to the CTRL_CORE_IPU1_IRQ_y_x register.

Thanks & Regards,
Shiou Mei
