How to export the latest linux kernel to OMAPL138

Cunman Zhang
Prodigy 80 points

Other Parts Discussed in Thread: OMAPL138, DA8XX, OMAP-L138

The PSP-3.22 runs well on my OMAPL138 board (boot from SD-card). But I have tried many days to debug the Syslink with no success.

So I googled and found the remoteproc in the newest kernel.

I use the configuration file: da8xx_omapl_defconfig (kernel 3.11.1). Tried different settings & modified the arch/arm/mach-davinci/board-omapl138-hawk.c.

The problem is: the generated uImage can not run. -- No output on terminal.

I had thought, the kernel could run on similar board with minimal modification. Can some board tell me what's wrong?

Works the hawk board from this kernel release?

Best regards,

Cunman

    Hi Cunman,

    SysLink/IPC runs only after the kernel is booted. So if you are not seeing any output this is unlikely to be SysLink-related.

    For help on the hawkboard, I suggest you consult the comnunity project page: http://elinux.org/Hawkboard. There should be folks on there who can help with your kernel build.

    Fyi, if you want to use IPC 3.x (aka "next-gen SysLink" that works with remoteproc) instead, please make sure you read the release notes and Install guide provided in the IPC product. The documentation contains information on patches that you may need to apply depending on the version of the Linux kernel you choose to use.

    Best regards,

    Vincent

    Hi Vincent,

    thank you very much for your reply!

    My problem is not about SysLink. It runs well, but I cann't debug it with CCS 5.1. The how-to-debug example fromTI-Wiki is for another SysLink/IPC version, in the newst SysLink version, files are changed. Each step is not so easy as man thought.

    That is the reason I want to try the new mainstream linux kernel. I hope I can load DSP firmware with remoteproc and debug it in CCS.

    I have some general questions about the linux kernel supported for OMAP-L138:

       1) why in the TI PSP-3.22.0.6 kernel there is arch/arm/mach-davinci/board-omapl138-lcdk.c but no board-omapl138-hawk.c, in the mainstream linux vice visa? Is there something conflect with the two boards (other than same machine-id)?

       2) in mainstream-linux: is there some "secret" initilzalizing code for hawk-board which makes LCDK not work?

       3) for mainstream-linux: is there a patch to make boards like LCDK to work.

       4) is the problem caused by cross-compile (I use arm-2009q1 which is recommanded for TI-PSP)

     

    Best Regards,

    Cunman

    I tried another method: use the tilinux-kernel from git: https://git.ti.com/ti-linux-kernel (3.12.0_rc1)

    The kernel runs with small modification: (da8xx_omapl_defconfig) + SD card (no CD/WP pins). But stops at:

        Waiting for root device /dev/mmcblk0p2...

    (The hardware has no problem, it can boot with PSP 3.22.0.6)

    I added some debug infor in driver/mmc/host/davinci_mmc.c, (also enabled DIV4 in MMCCLK register).

    The booting message looks like below: Can anyone mir help? Thx.
