Hi Karan,
we have made necessary changes you have mentioned(tic:916768) in R5F core. Now we are trying enable the Share memory In A72 side which runs Linux.
other than enabling shmmax in /etc/sysctl.d/99-sysctl.conf, kindly let us what else we have to do in Linux side to make use of shared memory.
#kernel.shmmax = 141762560
Thanks,
Rakesh T
