Hello,
I have issues using shared memory on i.MX53. I have two applications communicating together via shared memory. When I boot the system and I don’t start Xwindows and run the two applications I can have them communicate. But If I start Xwindows and I use xterm to run my applications they execute without any problem. I’m wondering what service Xwindows is activating to have the shared memory accessible? Does anybody know what may go on?
I get these outputs When I run the command: ipcs –m
a) This is what I get when it doesn’t work (running from linux Console):
--------------------------------------- Shared Memory Segments ------------------------------------------
Key shmid owner perms bytes nattch status
0x000005dc 0 root 666 1024 1
b) This is what I get when it works (running from Xwindows):
--------------------------------------- Shared Memory Segments ------------------------------------------
Key shmid owner perms bytes nattch status
0x000005dc 163840 root 666 1024 2
Thanks for your help,
:-)
