OMAP 3430 Camera/ISP out of memory error
Hi, i'm trying to get camera support working on a relatively new Android port to an OMAP 3430 based phone (Samsung GT-i8320 a.k.a. Samsung H1). However calls to VIDIOC_REQBUFS fail with a -12 (OUT OF MEMORY). As far as I can see this return error isn't even supposed to exist, according to the V4L2 spec. I'm using the code from Android on the Zoom2. The sensor is a Fujitsu M-4MO. Any ideas on what could be wrong with the out of memory result?

Re: OMAP 3430 Camera/ISP out of memory error
Ok, thanks! However, I'm also quite curious about peoples thoughts about it from here. Since I think what's happing is quite OMAP specific. For example, I was wondering where omap34xxcam.c gets it's memory it should allocate from. Is it the 'main' memory? Or does it share memory with a framebuffer (overlay)? Or memory from the (M-4MO) sensor? Is it possible I should allocate memory for it as boot argument? similar like vmem=16M omapfb.vram=0:8M I can't find much information about this all...

Re: OMAP 3430 Camera/ISP out of memory error
Thanks, I'm looking at http://gitorious.org/linux-omap/mainline/trees/master/drivers/media/video however, I can't seem to find the drivers I need. I only see omap24xxcam while I was using the omap34xxcam from Linux kernel 2.6.32.9. And I also don't see any M-4MO driver anymore. I'm probably looking at the wrong spot, but... As you can tell, I'm fairly new with OMAP programming. Thanks!

Re: OMAP 3430 Camera/ISP out of memory error
Thanks. I'm still not sure where to find an (the) up-to-date mainline. I was under the impression there's only one mainline? Regarding the older kernel, unfortunately I won't be able to choose for a newer version. The lead developer for this project did most of the work for the rest of the device with this kernel allready. So, I guess it's possible to backport the changes to the older kernel too right?
