Other Parts Discussed in Thread: OMAP3530

Hi all

I used the PSP2.0.0000 to compile cmemk and dsplink

cmemk is fine,but dsplink is wrong, the error is :

[root@OMAP3EVM /omap3530]# insmod dsplinkk.ko
insmod: cannot insert 'dsplinkk.ko': invalid module format

and I typed ----strings dsplink.ko | gre vernagic, it shows

vermagic=2.6.260omap1 mod_unload modversion ARMV7

-mod_vermagic6

but I check the cmemk.ko ,it is that:

vermagic=2.6.260omap1 mod_unload modversion ARMV7

-mod_vermagic5

I comile the dsplink throng the webpage :http://wiki.davincidsp.com/index.php/Building_DSPLink

step is

1 export DSPLINK and PATH （$DSPLINK/etc/host/script/linux）

2 edit BASE_BUILDOS and BASE_CGTOOLS in " make/Linux/omap3530_2.6.mk" and BASE_SABIOS and BASE_CGTOOLS in " $DSPLINK/make/DspBios/c64xxp_5.xx_linux.mk"

3 used perl dsplinkcfg.pl --platform=omap3530 --nodsp=1 --dspcfg_0=OMAP3530SHMEM --dspos_0=DSPBIOS5XX --gpp0s=OMAPLSP --comps=ponslrmc --trace= --legacy=1

4 use xdc -P clean and .interface command to dsp/src and gpp/src

5 make -s debug for them

where am I wrong ?

thanks for all

What version of dsplink do you have? DSPLINK 1.60 and newer require GNU Make 3.81 as noted in the documentation (InstallGuide_Linux_OMAP3530.pdf) included with DSPLINK installation. Many Linux Host OSes are still using GNU make 3.80.

make -version shows GNU make 3.81

I also notice that InstallGuide_Linux_OMAP3530.pdf (included in dpslink installation tree) show different build option in the pearl script, but thought yours should work as well. It is worth a shot using the build options provided in the documentation just to be sure.

I found something in /config/bin/dsplinkcfg,.pl

my %CFG_GPPOS_OMAPLSP =
(
    'NAME'   => 'OMAPLSP',
    'PREFIX' => '2.6',
    'ID'     => 'OMAPLSP',
    'DESC'   => 'OMAP LSP for OMAP2530 and OMAP3530',
    'VER'    => '2.6.18',
    'TYPE'   => 'Linux',
    'LOADERS'=> [\%CFG_LOADER_COFF, ],
    'COMPS' => 'ponslrmc',
) ;

my version is 2.26.22 provided in the psp 2.0 , when I tried to change it to 2.26.22, it showed error while i complied gpp/src

so i don't what i should to changed,

This is very interesting indeed; personally, I do not have much experience with omap software and do not have my installation handy to try this myself. If no one else chimes in, I may try to rebuild dsplink for omap tomorrow. what version of the omap DVSDK are you using?

That said, dsplink is a common component across many of our DaVinci and OMAP family of parts and I have rebuilt it many times; however, never with 2.6.22 kernel. I am not saying it cannot be done (I imagine it can), simply noting an interesting finding on your part.

Also, what is your goal behind rebuilding dsplink? FYI, it is my understanding that in newer versions of dsplink; starting with dsplink 1.40.03 and newer versions, you can configure dsplink dynamically without needing to rebuilt it. See http://wiki.davincidsp.com/index.php/Configuring_DSPLink_Dynamically for more details.

first , thanks for your help.

i used OMAP35x-PSP-SDK-setuplinux-02.00.00.01..bin

Today I heard TI have support DVSDK 3.0.

Indeed there is a DVSDK 3.0 release; FYI, you can find it here: http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/S1SDKLNX/DVSDK_OMAP3530/index_FDS.html

I still fail to understand why you need to rebuild dsplink;

We will continue to help you with this effort if you wish, but I just want to ensure you knew that you can configure dsplink dynamically as I did not want you wasting your valuable time in an effort that may not be necessary.

I want to make a good use of dsp for my board, and I dont how to use dsp first , so I need to use it in every aspect .

H264 is only a part, maybe the board will be uesd for video application, so I need to understand more about dsp.

So thank you for your help on it.
