syslink compile and vanilla kernel for L138

Massimiliano Cialdi
Expert 1995 points

Hi,


I can build and execute the last vanilla kernel 4.2.0 (mainline git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git) for L138 (using davinci_all_defconfig) on L138 experimental kit (ZOOM by logicpd).

I have some problems building syslink. Is there some patch or "dedicated steps" to build syslink using a mainline kernel? Maybe syslink build with kernel 4.1 or above?

best regards

    I solved the build issue:

    just follow the speps described here: http://processors.wiki.ti.com/index.php/MCSDK_OMAPL138_User_Guide_Chapter_Exploring#Build_Syslink

    and two other change (asm/system.h become asm/system_info.h in file packages/ti/syslink/utils/hlos/knl/osal/Linux/OsalIsr.c and ioremap_cached() become ioremap_cache() in file packages/ti/syslink/utils/hlos/knl/osal/Linux/MemoryOS.c)

    these changes make syslink to build without errors, but the module cannot be loaded:

    syslink: Unknown symbol putname (err 0)
syslink: Unknown symbol getname (err 0)

    so also the kernel needs to be patched to re-export the symbols getname/putname in file fs/namei.c

    At this point syslink can be loaded, but tryng the examples the fails.

    root@arago:/ex02_messageq/release# ./run.sh 
+ ./slaveloader startup DSP server_dsp.xe674
Attached to slave procId 0.
Loading procId 0.
Error in ProcMgr_load [0x83046005]
+ ./app_host DSP
--> main:
--> Main_main:
Main_main: load callback failed
<-- Main_main:
<-- main:
+ ./slaveloader shutdown DSP
Stopped slave procId 0.
Unloaded slave procId 0.
Detached from slave procId 0.

    best regards

    Hi,
    We have not tested syslink with latest kernel version.

    this is helpful, I met those errors when making syslink. After modified two files, making syslink successed. Thanks.
