DRA726: yocto question

Michel Catudal
Genius 3825 points
Part Number: DRA726

I am creating a yocto based on  SDK rev 5, currently using version 3.04

The newly created image boots correctly except that weston is not working

I then noticed this in packagegroup-arago-tisdk-multimedia.bb

ACCEL_FW_append_dra7xx-evm = " \
    ${@bb.utils.contains('MACHINE_FEATURES', 'mmip', 'ipumm-fw', '', d)} \
    vis \
"

It is not likely the cause for this problem as I don't see the EGL libraries

I have  "require conf/machine/include/dra7xx.inc" in my actia-gd.conf file
which has "require conf/machine/include/omap-a15.inc"
which has :

MACHINE_FEATURES = "kernel26 apm usbgadget usbhost vfat ext2 screen alsa ethernet sgx mmip dsp"

What am I missing? I followed Brad's seminar close so I thought I took care of everything.

My machine is not dra7xx-evm, I call it actia-gd and distro named actia,  we have a custom board

Since our board differs a lot from the evm I need to customize both u-boot and the kernel. Much the same as with 3.04

My challenge once I get this to work is to get the analog cameras to work with cal.c where major modifications have been made since the kernel in rev 3.03

We use an intersil device with 4 cameras mutliplexed on the CSI port

This is the log for weston

    Hi Michel,

    -1-

    Let me start responding to you by asking you if your generated filesystem has the "/usr/bin/pvrsrvinit" and then is there the systemd service that starts this automatically? If these two things are not present then you are likely to run into this issue.

    -2-

    Could you please manually run "pvrsrvinit" and then try to launch weston? 

    Please make sure that that the actia-gd is closely resembling the dra7xx-evm and including the necessary dependencies.

    Please share the feedback on both the questions.

    Regards

    Karthik

    rc.pvr has

           if ! /usr/bin/pvrsrvctl --start --no-module; then return; fi

    Here is something interesting

    HI Michel,

    The errors

    PVR:(Error): OpenServices: PVRDRMOpenRender failed [0, ]
    PVR:(Error): PVRSRVConnect: Unable to open connection. [0, ]
    PVR:(Error): Couldn't connect to services [0, ]

    conclude that one module pvrsrvkm.ko is not inserted.  Please make sure two modules pvrsrvkm.ko and bc_example.ko are built and copied to /lig/modules/4.14.xxx/extra  

    Please refer the recipe for sgx-km

    http://arago-project.org/git/?p=meta-ti.git;a=blob;f=recipes-bsp/powervr-drivers/ti-sgx-ddk-km_1.14.3699939.bb;h=24d8d1d2e8530c728ae45a23ca1e9e80e1435dac;hb=refs/heads/rocko

    2) With these two modules available, rc.pvr init script should be able to load the pvr 

    Weston will be launched successfully with this.

    Can you please check if you have copied both the kos ?

    Thanks

    RamPrasad

    Hi Michel,

    Can you execute these 3 instructions in this order and check?

    modprobe pvrsrvkkm

    pvrsrvctl --start --no-module

    modprobe bc_example

    Thanks

    RamPrasad,

    I was off Thursday and Friday for the Thanksgiving holiday.

    root@actia-gd:~# pvrsrvctl --start --no-module
    PVR:(Error): OpenServices: PVRDRMOpenRender failed [0, ]
    PVR:(Error): PVRSRVInitSrvConnect: PVRSRVConnect failed [0, ]
    PVR:(Error): SrvInit: PVRSRVInitSrvConnect failed (4) [0, ]
    pvrsrvctl: SrvInit failed (already initialized?) (err=PVRSRV_ERROR_INIT_FAILURE)

    I get the same kind of crash when I do the modprobe bc_example

    If I move the modules somewhere else and reboot I get different results

    I moved the modules back to the extra directory

    root@actia-gd:/lib/modules# pvrsrvctl --start --no-module

    Hi Michel,

    Does modprobe pvrsrvkm.ko works without any error?

    Can you try to build the sgx modules once from installer and give a try?

    The path for the sgx-km is here board-support/external-linux-kernel-modules/omap5-sgx-ddk-linux/ 

    Thanks
