hello everyone ( i am not good at English )
i use P2020 and P1011 and OS is linux
at last time i use CPM2 timer and kernel driver at linux 2.6.29, CPU was MPC8248
but kernel is a lot different from old one and CPU and the way to use interurpt are much more complex
in CPU Reference Manual it says it has timers at overview section
i am not sure it means Global timer regsiters ( in Programmable interrupt contoller )
but i have no clue how to use it ?
do i need to change DTS file ?
in linux source code, there is a fsl_gtm.c ( gerneral timer ) file
could i use it and how could i use it ?
is there any example to use fsl_gtm ?
thank you in advance
