Part Number: PROCESSOR-SDK-AM62X


HI,
I use SDK  for ti-processor-sdk-linux-am62xx-evm-09.00.00.03 on AM6254 。 ddr4:512M .

1、now the linux system works . but in the startup . the psplash-star.service is failed , the ti-apps-launche.service is failed.

I use the systemctl command . below is information :

root@am62xx-evm:~# systemctl status ti-apps-launcher.service

2、I use  lsmod

the pvrsrvkm.ko  didn't  auto loaded .

so how to solve it ?
could you give me some advices ?  Thanks very much!

    Hello,

    Have you compiled the GPU module? In general, how are you are you generating rootfs and compiling Kernel? Are you using the sources directly from the SDK?

    Regards,
    Krunal

    Hi， I compiled the Kernel and extra-drivers. 
    I used rootfs directly from SDK .  I  decompression  tisdk-default-image-am62xx-evm.tar.xz to SD card parition two of ext4 pattern.
    then I install kernel modules to sd rootfs  with command(sudo make ARCH=arm64 INSTALL_MOD_PATH=/media/hj/rootfs modules_install).
    and I copy extra-drivers  (cryptodev.ko and  pvrsrvkm.ko) to rootfs .the path is /lib/modules/6.1.33-g40c32565ca/extra.

    so do need to compile the rootfs ?

    No, you don't need to compile rootfs. You mentioned that you manually copied pvrsrvkm.ko and what happens if you manually insmod it?

    Hi ，I can  insmod pvrsrvkm.ko manually. then I run qt application ,like hellogles3, I  found the cpu mem has used 90%.

    1、I have do some other test . I found if  I use default rootfs of ti-sdk-9.0.03's filesystem . Ijust change the k3-am625-sk.dtb. the linux system could run .all the modules loaded ok . but the tidss driver has probole . the information is: tidss 30200000.dss: tidss_encoder_atomic_check: No bus_formats in connected display。  I use  rgb888. the  dts configure is below:

    panel_rgb: panel-rgb {
    compatible = "panel-dpi";
    //backlight = <&backlight_rgb>;
    //power-supply = <&vdd_rgb>;
    status = "okay";

    panel-width-mm = <68>;
    panel-height-mm = <121>;


    panel-timing {
    clock-frequency = <85500000>;
    hactive = <1366>;
    vactive = <768>;
    hback-porch = <223>;
    hfront-porch = <60>;
    vback-porch = <24>;
    vfront-porch = <3>;
    hsync-len = <143>;
    vsync-len = <3>;
    hsync-active = <1>;
    vsync-active = <1>;
    de-active = <1>;
    pixelclk-active = <1>;
    };

    ports {
    #address-cells = <1>;
    #size-cells = <0>;
    port@0 {
    rgb_in1: endpoint {
    remote-endpoint = <&dpi1_out>;
    };
    };

    };

    };

    &dss {
    pinctrl-names = "default";
    pinctrl-0 = <&main_dss0_pins_default>;
    status= "okay";
    };

    &dss_ports {
    #address-cells = <1>;
    #size-cells = <0>;

    /*VP2:DPI OUTPUT*/
    port@1{
    reg = <1>;
    dpi1_out:endpoint{
    data-lines = <24>;
    remote-endpoint = <&rgb_in1>;
    };
    };
    };

    so the bus_formats how to configure in the dts ?

    2、 I  compiled  kernel  in the ti-linux-kernel  with the  default  config (make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- defconfig ti_arm64_prune.config). then i install the kernal module to rootfs(sudo make ARCH=arm64 INSTALL_MOD_PATH=/media/hj/rootfs modules_install).the linux system run ,but the module pvrsrvkm.ko didn't load .and the hw time sync and  ti-apps-launcher.service failed.
    why coule  the compiled the kernel and module run ?

    3、if  I just update  the compiled  kernel , this kernel couldn't load the default module of rootfs .this is very strange . do I forget configure something ?
     I  referenced :https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_00_00_03/exports/docs/linux/Foundational_Components_Kernel_Users_Guide.html#getting-the-kernel-source-code

    what's the problem ?could you give me some useful advices ?

    Hi Helen,

    Krunal is out of office this week as he is on travel. While he returns, have you tried to use the default Image that comes with our SDK release? The latest SDK release is 9.1.

    https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-PvdSyIiioq/09.01.00.08/tisdk-default-image-am62xx-evm.wic.xz

    Let me know if you still see issues with apps launcher/psplash?

    Best Regards,

    Suren

    Hi Suren,
    in the  sdk09.00.00.03.I use command(make all ). I found the toolchain is  aarch64-oe-linux-gcc, this is for oe operation system . I comipled the ti-linux-kernel use the toolchain aarch64-none-linux-gcc.so The issues is caused by the  different toolchain ?

    Hi ,I have fond the problem of the issue. pvrsrvkm.ko need to copy to the module of rootfs . then to update the map file . now the system run ok . Thanks very much!
