TI PRUSS remoteproc support doesn't exist in the Remoteproc drivers

Intellectual 330 points

I've followed the instruction to install the Sitara Linux SDK v8.0 and the PRU Software Support Package successfully. Then, I 've followed the instruction to apply the pru patches to the linux kernel successfully. Now, I am following the instruction to enable PRU Support in kernel. When I come in the Device Drivers -> Remoteproc drivers via menuconfig, I find there doesn't exist the option "TI PRUSS remoteproc support". Moreover, there does not exist the option "AM3xx wkup-m3 remoteproc support".

here is the figure

what's the problem? Is there any steps I need to do? How can I fix my problem?

P.S. I have not intalled the CSS in my linux host computer. Is CSS necessary for this configuration?

Thanks!

    Thanks for replying.
    I have already fixed this problem. The reason is that I haven't use the file "singlecore-omap2plus_defconfig", after using this configuration, I can see the option "TI PRUSS remoteproc support" in the Remoteproc drivers.
    Thank you again!

    Hello,
    I have the same problem. I can't find the "TI PRUSS remoteproc support" in the menuconfig. How have you fixed this issue.
    I have installed the "ti-sdk-am335x-evm-08.00.00.00-Linux-x86" and then I installed the "pru-addon-v2.0-Linux-x86." following the document processors.wiki.ti.com/.../PRU-ICSS_Installer.

    Someone could help me? Thanks

    P.S: I'm working on a v.m. (VMware) and the O.S. is Ubuntu 14

    Hi Matteo,

    Please refer to http://processors.wiki.ti.com/index.php/Linux_Kernel_Users_Guide 

    you can type in the command below first.

    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- singlecore-omap2plus_defconfig

    Then you type in the command

    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig

    In Device Drivers->Remoteproc drivers, you may find things you want.

    Thanks for your fast reply!
    the answar to the first command is "No rule to make target 'singlecore-omap2plus....'. Stop".

    I don't know if is necessary, but if I check in the folder "../ti-sdk.../linux-devkit/sysroots/i686-arago-linux/usr/bin" I can't find the file "arm-linux-gnueabihf- singlecore-omap2plus"..

    Thanks again for your help

    Hi Matteo,

    Have you referred to http://processors.wiki.ti.com/index.php/Linux_Kernel_Users_Guide ?

    Actually, you should go into the directory /home/user/ti-processor-sdk-linux-am335x-evm-01.00.00.00/board-support/linux-3.14.26-g2489c02 (similar with SDK8.0) before you use that command.

    now I'm able to edit the config by menuconfig, but I'm not able to generate a new image. The sequence of command and answares are these:

    Why it can't find the file "arm-linux-gnueabihf-gcc"? This file is present in the folder  ti-sdk-am335x-evm-08.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin... 

    What can I do?

    Thanks Again for your Help

    Matteo,

    I believe you may have missed the step to export the path to your toolchain:

    http://processors.wiki.ti.com/index.php/Linux_Kernel_Users_Guide#Compiler

    Or, you did this step, but in another instance of your terminal.

    You can use "echo $PATH" to check.

    Hello,

    The PATHs that I have set are:

    troppoteo@ubuntu:~/ti-sdk-am335x-evm-08.00.00.00/board-support/linux-3.14.26-g2489c02$ echo $PATH
    ti-sdk-am335x-evm-08.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

    the paths should be right?!?!

    Thanks

    Matteo

    Matteo,

    I believe you may be missing a '/' at the beginning of the path to the toolchain. One way to verify would be to go to 'ti-sdk-am335x-evm-08.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin' where you've verified the tools are, and issue a 'pwd' command. The output of this command needs to be in your path. I believe it should start with a '/'.

    Thanks for your help. Now I updated the image on my sd card.
