error on target machine(pxa255+linux-2.4.19) when runing rmtsvr!

[nengneng]

hi ,i installed vtune 7.2 on my host ,recomplied the sourceunder C:Program FilesIntelVTuneRDC for XSC2TargetMVLCEE3.0vdkvdk_src_1.02vdk with arm-linux-gcc and get a driver vtune_drv.o and copy it to my target. Meanwileitranferred some files(rmtsvr,vtlxsc,insmod-vtune.sh)under C:Program FilesIntelVTuneRDC for XSC2TargetMVLCEE3.0vtutility_by_iwmmxt_le to my target machine . i run the insmod-vtune.sh and the message is below:

#/root>./insmod-vtune.sh

*STATUS* Sampling driver vtune_drv has been successfully loaded.

then i run rmtsvr programme,there is an error below:

#/root>./rmtsvr
rmtsvr (184): undefined instruction: pc=00009ea8
Code: 00028070 00028080 e1a0c00d e92ddff8 (ed6df102)

i run vtlxsc and there is also error:

#/root>./vtlxsc

why? should i recomplie the vtlxsc and rmtsvr with arm-linux-gcc?but i haven't the sources .

help!!!

[Peter_W_Intel]

First all, I believe that VTune Analyzer 7.2 supports MVLCEE3.0 and I don't think that you have to rebuild vtlxsc and rmtsvr. One thing may be missed of doingfrom you side after insmod vtune_drv.o - that is, you have to do mknodfor character device as below:

#cat /proc/devices

162 raw

252 vtdev

253 pcmcia

# mknod /dev/vtune_d c 252 0

# mknod /dev/vtune_m c 252 1

Also please note that prebuilt utilities in VTune is for PXA27x and you are working on PXA255.

You can use http://premier.intel.com to submit any issue, if you have concerns on this.

Regards, Peter

[nengneng]

i check the /dev and there are two nodes vtune_d and vtune_m.the driver vtune_drv.o hasbeen installed successfully.

Since the rmtsvr and vtlxsc are for pxa27x, where can i get rmtsvr and vtlxsc for pxa255 ?

[Peter_W_Intel]

I ever used rmtsvr on former version for pxa255/kermel 2.4.18. please try it.

[nengneng]

hi ,i just run the rmtsvr in my target machine,when i run the XscVTuneHostDC.exe on my PC,there is an error below:

it's a pity that itcan't be used.can you give me the souce of the rmtsvr and vtlxsc or tell me the mechanisms of the two program.

[nengneng]

we use arm-linux-gcc 2.95.3 to compile our kernel(2.4.19).does that matter?

[Peter_W_Intel]

I noted that you got error message after connection establishing. I remember that I used thatwith VTune Analzyer 7.1 host and gcc is 2.95.3. Is that the reason that you use itwith 7.2 host?

I searched another rmtsvr, which is under my VTune 7.2 folder. Would you like to try it with 7.2?

I strongly suggest you to submit this issue on premier, that system will trick this issue status and work efficiently.

[Peter_W_Intel]

You can see message - Version: 7.1.6.215. You have to use my first attaching one with VTune Analyzer 7.1...

[Peter_W_Intel]

Please use "root" user to run rmtsvr, I have seen there message -

"Flags: nzCv IRQs on FIQs on Mode USER_32 Segment user
Control: 397F Table: A3A98000 DAC: 00000015
Segmentation fault"

on user mode, you can not access PXA255 hardware.

[nengneng]

Excuse me!where can i get the vtune 7.1 evaluation.i will try but i can only find vtune 7.2 in your company's website

[Peter_W_Intel]

version 7.1 is face-out, let's back to 7.2. My folk thought itis the reasonthat utility (in 7.2) was built by MVLCEE3.0, and you are using arm-linux-gcc. please try his rebuild one again on attached!!

[nengneng]

yesterday i deleted the vtune 7.2 on my computer ,then i went to www.intel.com/software/products/vtune/downloads/vtune_eval.htm and down load the vtune 7.2's w_vt_p_7.2.034_ev05.exe on HONGKONG mirror site, but when i run it there is aNSIS Error:

" the install youare trying to use iscorrupted or incomplete.this could be the resultof a damaged disk ,a failde download or a virus. you may want to contact the author of this installer toobtain a newcopy.It may be possibile to skip this check usingthe/NCRCcommandline switch(NOT RECOMMENDED)."

I told to my fellow and he downloaded it again an run it in his computer ,but he failed too.

would you mindcheck the w_vt_p_7.2.034_ev05.exe on you website?wait for your reply! thanks a lot!

[Peter_W_Intel]

For quick work around, you can access ftp download URL at ftp://download.intel.com/software/products/vtune/downloads/eval/

I just wonder if you uninstalled the product, why can't you find extracted package at C:Documents and Settingszwang14Local SettingsTempw_vt_p_7.2.034 in my case.

[nengneng]

with your help ,i have resolved all problems! thanks a lot!!!

what may be the problem ? thanksa lot!

[Peter_W_Intel]

Last time you said all problems are solved. Haven't you run rmtsvr before? or just today you meet this?

[nengneng]

we have two types of target machine: one is pxa255+32m norflash+linux 2.4.19 and the other is pxa255+1m nor flash +32 m nand flash+linux 2.4.19.

last time i use the second target(pxa255+1m nor flash +32 m nand flash+linux 2.4.19),the rmtsvr can work on it. and today i use the first target( pxa255+32m norflash+linux 2.4.19),but the rmtsvr can not work.i'm puzzled! i don't kown wherethe probem occur,the hardware or the software? in the debug info i can see the device(vtune) is open,but it can't connect withthe host. when the system run ,i rmove most of the modules butthe rmtsvrstillcan't work.ialso rebuild thebzImage withe gcc 2.95.3 and 3.3.2 .in the two kernels the rmtsvr can't work either.

[Peter_W_Intel]

Have you used MV VDK driver on first board? Make sure it is rebuilt one for arm linux.

[nengneng]

Canyou tell me the version of arm-linux-gcc ,GLIBC ,binutils which you use to build the rmtsvr and vtlxsc given to me last time.In my target, we use zImage and rootfs with arm-linux-gcc (GCC) 3.3.2, glibc 2.3.2 and binutils 2.14.90.0.7.ithink itmaybethe problem!

[Peter_W_Intel]

gcc, glibc 3.2.1

[nengneng]

thanks a lot ! i rebuild the driver and it works well on my first and sencond machine!
