Tried the omapfb X driver.

Got a black screen.

Here's my log :

Another thing (using autoloaded fb driver), i can't see picodrive rendering, but pcsx rearmed works fine. Fun.

FRZ · Feb 3, 2012

Hi, question. Did you do everything from your OpenPandora?

Linux-SWAT · Feb 3, 2012

The distro's install is made through my PC. I grouped useful scripts/sources/etc. that i put on the SD too.

After that, i prefer to compile the kernel and libraries on the host, even if it's slow (can do other things aside).

I currently struggle with the TI graphics drivers.

ok. when are you gonna do a video for us to see it running on your unit. though im a linux noob. I have been installing slackware on my laptops since version 9 or so. I currently have 13.37 install on my win7 installation through virtualbox, (first time). I 've had always had a dual boot system.

Linux-SWAT · Feb 4, 2012

Well there's many things to setup. You can taste some screenshots of the 12.2 up in this thread.

I now succeded into installing a 13.37. I even run KDE 4 ^^.

Basic controls works, but some things are not yet supported by 3.2.1 kernel, like cpu mHz settings.

Linux-SWAT · Feb 25, 2012

I'm a bit stuck with the 3d driver.

Dunno if it's the correct way to (un)set toolchain pathes.

I want to compile native :

Code:

#Rules.make

http://git.openpando...90eecde;hb=HEAD

I used patch 0002-Compile-fixes-for-recent-kernels.patch

Do i need all the other ? Some lines reports for 2.6.X.

notaz · Feb 25, 2012

I did not need to edit Rules.make, only Makefile in GFX_Linux_KM, and build it from there.

Here is a hacky patch I used to build this for 3.2:

Maybe it's because i removed debug folders to gain space ?

Or i patched with 0002-Compile-fixes-for-recent-kernels.patch before ?

notaz · Feb 26, 2012

Hmh maybe I used the wrong base, try redownloading and reapplying (without the OE patches):

http://notaz.gp2x.de...00_01_3.2.patch

oh and do 'make TI_PLATFORM=omap3430'

Linux-SWAT · Feb 26, 2012

Worked fine, thanks.

Modules loaded.

The pvr-init script hat to be started before X ?

I think i have to modify my xorg.conf now.

notaz · Feb 26, 2012

SGX has little to do with X, you can start it anytime and no Xorg config editing is needed.

You do need SGX binary blobs that are in various .so files and some tools (at least pvrsrvinit):

http://www.openpandora.org/feeds/unstable/armv7a/libgles-omap3_4.00.00.01-r3.5_armv7a.ipk

Linux-SWAT · Feb 26, 2012

cputype, devmem2 and pvrsrvinit i suppose ?

I copied them from OP rootfs, and got :

/usr/bin/pvrsrvinit ... error loading shared libraries: libsrv_um.so

I hope it's included ^^.

Thx.

Linux-SWAT · Feb 26, 2012

Code:

strace pvrsrvinit

reports i have no /dev/pvrsrvkm

Dunno mknod numbers since not listed in /proc/devices :/

notaz · Feb 27, 2012

They should show up when you insmod pvrsrvkm.ko.

Linux-SWAT · Feb 27, 2012

Weird. I'm back with official OP kernel for now.

I have another things to report :

1-On my 1st normal OP, console keyboard is weird, and when booting the same slack SD card on my non-wifi OP, the console keyboard is ok.

I use the official /etc/keymap-extension-2.6.map.

Checked dates, it's OK.

2- I have to manually modprobe usb-ehci. Others modules are well auto-loaded.

notaz · Feb 27, 2012

1. weird, I haven't seen this.

2. it's done on purpose - usb-ehci doesn't support power saving so not inserted by default to save power.
