Hi :
I have questions about the Keystone2 IPCG . accordoing to the datasheet. 66AK2H12 has 12ge IPCGR register and it can trigger interrupt to anycores .
for example :dsp to dsp ,arm to arm and arm to dsp ,dsp to dsp.
Currently , I meet a problem that is ARM can trigger DSP interrupt while DSP cannot trigger ARM interrupt. In my projoect , ARM is running on vxworks . I also check the GIC interrrupt registers and IPCAR regters . the IPCAR has been trigger and GIC SPI interrupt has been enable .
Can you give me some advice ? thank you
