Hi All,

I'm creating the timer with using SYSBIOS Configuration(*.cfg file) as below and it is working.

var Timer = xdc.useModule('ti.sysbios.timers.dmtimer.Timer');

In addition, I would like to set the interrupt priority of this timer above the others peripheral (GPIO, CAN, UART, Ethernet).

Could you please let me know if there were ?

Hi JY,

You can use HWI_create() function to setup the Timer interrupt. You should set Hwi.params priority to higher (than GPIO, CAN, Eth) value:

software-dl.ti.com/.../Hwi.html

var params = new Hwi.Params;
params.priority = Int -1;

Check also below e2e threads:

e2e.ti.com/.../779630
e2e.ti.com/.../299842
e2e.ti.com/.../733318
e2e.ti.com/.../763488

Another approach is to use the CSL_xbarIrqConfigure function, together with Intc_IntPrioritySet()
