I find a IPC example project . in the project core0 triger ipc interrupt to core1.
and core1 trogers ipc interrupt to core2,and so on.i have no EVM board and this project is run under simulator mode.
I defined a glbal variable 'int g_flag = 3'.In the correspondig ipc_isr function, i added one to g_flag and
print its value in console.
however the output message is below , it looks as if the global variable added only once . it means the variable is not shared by all the eight cores.
how to define and use a global variable that can be operated by all cores on DSP6678 under IPC ?thanks.
