OMAP3EVM PowerVR SDK Problems

Other Parts Discussed in Thread: SYSCONFIG

 

Hello,

        I’ve downloaded the OpenGL SDK v3.00.00.08a and the latest PSP (OMAP35x-PSP-SDK-02.01.02.09) and am using the arm2007q3-51 version of the CodeSourcery toolchain – I’m running into problems getting the OpenGL kernel modules to load on the Linux kernel on the OMAP3EVM – I’ve applied the SGX patches (found in sgx_kernelmodule_patches), and noticed that the psp_kernel_patches/*.patch have already been applied on the Linux kernel (so I did not apply them). 

When I try to load the three kernel modules, I get errors. Loading pvrsrvkm.ko goes without incident. Loading omaplfb.ko produces the following error:

<4>omaplfb: no symbol version for PVRGetDisplayClassJTable
omaplfb: no symbol version for PVRGetDisplayClassJTable
<4>omaplfb: Unknown symbol PVRGetDisplayClassJTable
omaplfb: Unknown symbol PVRGetDisplayClassJTable
insmod: cannot insert 'omaplfb.ko': unknown symbol in module, or unknown parameter

Has anyone else come across this error in the latest releases? A peek into the OE (OpenEmbedded build system) recipes for the 08a kernel module build shows a number of patches being applied to get it working.

Thanks,

Jerry

    I'm getting the same issue.

    Following your procedure I have succesffully built and loaded the kernel modules. When I go to run the test I receive the following error.

    # ./gles1test1 -t                                     
    'eglInitialize' returned egl error 'EGL_NOT_INITIALIZED' (0x3001)

    It should be noted I am using Graphics SDK 3.00.00.08 with PSP 2.01.01.08 on OMAP3EVM board. I am using pre-built kernel, and GFX SDK NFS filesystem. I have replaced pvrsrvkm.ko and omaplfb.ko, and modified /etc/init.d/rc.pvr to change "modprope -f" to "modprobe -q" and remove the bc_example.ko stuff as it is not built using your method.

    Perhaps this has been address in 08a or 09. I will try these out if you haven't encountered the issue I have above. These were printed during startup:

    EGL library does not support RGB888 !!!                                        says it all

    I have the same issue on my beagleboard, I can only get it to work with a RGB565 framebuffer, to set it up in u-boot, I used (note this may differ on different boards and kernels, the omapfb.mode is the one that matters):

    nand erase 260000 20000
    setenv bootcmd 'mmcinit; fatload mmc 0 0x80300000 uImage; bootm 0x80300000'
    setenv bootargs console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait omapfb.mode=dvi:1280x720MR-16@60
    saveenv

    to get a 1280x720 60hz 16 bit framebuffer, then the PVR driver loads OK and I can run the examples and Qt, be sure to edit /etc/powervr.ini I had to replace the flip-library with libpvrPVR2D_FRONTWSEGL.so in there, as I can't get FLIP to work neither.

    I can not find the patch sgx_kernelmodule_patches in OMAP35x_Graphics_SDK_3_00_00_09.

     

    Thanks for any help!

    I dont think you need a patch for 3.0.0.9 sdk.
