IPC hw interrupt generation problem

I am trying to send IPC interrupt between ARM Cortex A-15 processors in TCI66AK2H12 board and OS is SYS/BIOS.

I've cerated an hw interrupt with the configuration below.

    Hwi_Params_init(&hwiParams);

    hwiParams.triggerSensitivity = 0x03;

    hwiParams.eventId = CSL_ARM_GIC_IPC_GR9;

    Hwi_create((37), myIpcIsrFunc, &hwiParams, NULL);

this configuration creates an interrupt with eventId 5 which is ARM CORE 1 IPC event ID.

In order to trig IPCGR9 register, I used below code. Kicker have to be unlocked before writing to IPCGR9, because IPCGRx register is in the BOOTCFG area. 

CSL_BootCfgUnlockKicker();

*(unsigned int *)(0x02620264)=(0xFF<<4)|0x1;

CSL_BootCfgLockKicker();

But interrupt is not working. myIpcIsrFunc does't called. I don't know where the problem is.  Hw interrupt creation or triggering the interrupt.

Thanks

    Hi muhammet,

    Could you please confirm your DSP part number? 

    TCI66xx devices are supported directly through Local Field Applications Engineers (FAEs.)  These devices are not supported on the E2E forum.  Please contact your local FAE for support of these devices.  If you are not sure who your local FAE is, then please contact your local technical sales representative and they will be able to put you in contact with your local FAE.

    Thanks.

    Hi Rajasekaran

    I use EVM TCI66AK2H12

     

    thanks

    Muhammet,

    For KeyStone II (MCSDK 3), look at the two include files csl_cpIntc.h and csl_cpIntCAux.h to see all the API that are needed.
    Find an examples in the release MCSDK_3_01_12\pdk_keystone2_3_00_01_12\packages\ti\drv
    There are examples that use interrupts from peripherals.

    Read the following wiki page,You can find the code snippet of an example of creating an HWI instance.
    http://processors.wiki.ti.com/index.php/Configuring_Interrupts_on_Keystone_Devices

    Please mention the device number instead of EVM / Board.

    Hi Pubesh

    Thanks for  the docs.  Sorry about the late response, there were other higher priority works to do

    Device number TCI66AK2H12

    I can send ipc interrupt from ARM CorePac Coretex A-15 Core1,2 to Core 0 but Core1 and 2 still doesn't get the interrupt from other ARM cores.

    thanks

    Hi Muhammet
    Could you please let us as what mechanism did you use on the ARM side to send the IPC interrupt to DSP. If possible can you share me the sample code.
