Hi all,

Do you have any workable example for the timer interrupt on EVMK2H ARM processor?

I try to modify the CSL example but cannot resolve "undefine reference" of function CSL_intcInit().

My project is as below:

ARM_Timer.zip

Thanks a lot.

Hi,

It looked the code you referred to is \pdk_k2hk_4_0_16\packages\ti\csl\example\timer\timer_test.c. This is code for C66x and interrupt architecture is different between C66x and ARM, it is not expected to work.

We don't have any bare metal timer interrupt example on A15, mainly there is no example how to set up interrupt. I have some SYSBIOS timer example on A15 of another processor (AM572X), that may work as a starting point for this purpose.

Hi,

AM572x uses dmtimer, K2H use timer64. Attached is one tested on K2H A15 core.
