Our board was ported some two months ago by DENX software based on the MPC8= 272 (freescale) . I'd like to add the support for shared memory , but as I said I'd like to k= eep the system as untouched as possible - as I said It's been tested and is= running stable and with good performance . Since I know that these things are delicate, I'd appreciate your guidance a= s to which files I need replaced (by which files) , and which configuration= s need be changed . Best Regards, Yigal Goldberger . --- On Fri, 10/16/09, Gilles Chanteperdrix wrote: > From: Gilles Chanteperdrix > Subject: Re: [Xenomai-help] shm_open returns errno 38 - function not impl= emented > To: "Yigal Goldberger" > Cc: xenomai@xenomai.org > Date: Friday, October 16, 2009, 4:18 PM > Yigal Goldberger wrote: > > Gilles, > > Thanks for the answer. > >=20 > > I need shared memory only between user space > applications , so I do prefer the second option.
