Hi,

Have you made sure to run the omap-demo script?

http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide#Step_2_:_soc_demo_script_verification

Also please share your complete bootup & execution logs(commands/scripts you would have run).

Thanks,

Prathap.

Hi Pratap,

Thanks for replying back.

Yes, the script runs the omap-demo script.

Please find the attachment of bootup and execution log.

Thanks,

Prabha

Hi Prabha,

From the logs you provided, it looks like there is a problem writing to the SGX functional CM_FCLKEN_SGX (0x48004B00) & interface clock registers on your board.

Can you please comment out the running of omap-demo script as part of init script?. Allow the linux to boot & at command prompt do the steps one by one manually & see where things are going wrong.

Using devmem , can you provide the dump of the feature status register - 0x4800244C(CONTROL_FEATURE_OMAP_STATUS Register) once the linux boots up.

Also write to the registers one by one using devmem as below -

/etc/init.d/devmem2 0x48004B48 w 0x2
/etc/init.d/devmem2 0x48004B10 w 0x1
/etc/init.d/devmem2 0x48004B00 w 0x2

First check whether you can read all registers (for this you can use devmem without the w option ie for eg devmem2 0x48004B48 would give the value of the register).

Then try writing one by one & see where its failing. You can also refer to TRM for understanding more on these registers if required.

Thanks,

Prathap.

Hi Prathap,

Sorry for the late reply.

As you said i commented the omap-demo script and allowed teh linux to boot. And at the command prompt i issued below given commands:

BusyBox v1.20.1 (2012-11-20 16:59:59 IST) built-in shell (ash)
Enter 'help' for a list of built-in commands.

Hi Prathap,

One additional input same code is working fine for REV C beagleboard and read of 0x50000014 is working fine in Rev C4.

1. I tried to understand what register "0x50000014" (SGX register register memory map from DM3730-TRM-pdf) and whether there is any change in register memory map between Rev C4 and xM. It has for all registers (0x48004B48, 0x48004B10, 0x48004B10), except 0x50000014

(Please provide links to relevant pdf to understand what the specific register is about)

2. Any reference links/blogs you can provide where SGX is working fine in Beagle board xM

Regards

Prabha

Hi Prabha,

Thanks for the additional inputs. Appreciate it.

0x50000014 is the SGX Revision register. It will provide the SGX core version present on the board.

For eg on my 3730 EVM setup, the dump is as follows -

# /etc/init.d/devmem2 0x50000014
/dev/mem opened.
Memory mapped at address 0x40329000.
Value at address 0x50000014 (0x40329014): 0x10205

But i am seeing the problem with the dump of  CONTROL_FEATURE_OMAP_STATUS register (0x4800244C) on your board. It should give value of 0x0 for 13-14 bit.  It means SGX is available with full speed clock. I am getting the expected value on my 3730 EVM setup as below -

# /etc/init.d/devmem2 0x4800244C
/dev/mem opened.
Memory mapped at address 0x40447000.
Value at address 0x4800244C (0x4044744c): 0xC00

Can you please check the values for 13-14 bit on your Rev C4 and xM setups? The details of this register( CONTROL_FEATURE_OMAP_STATUS) is  available in the 3730 TRM.

Thanks,

Prathap.

Hi Prathap,

Thanks for the reply.

I had one more xM board. So i tried the same on that board.

I am getting the value on my another xM board setup as below:

With the old board i am getting same error(Bus error ) and value of 0x4800244C register is 5C00

I searched in the TRM guide for the CONTROL_FEATURE_OMAP_STATUS register,but i didn't get any details in that pdf.I am reffering sprugn4r.pdf.

1.Is 0x4800244C register is a read only register?

How to resolve this? Am i missing any patches?

I am facing one new problem with my new board.

I have compiled my Garphic SDk with make ARCH=arm OMAPES=5.x SUPPORT_XORG=1 all and make ARCH=arm OMAPES=5.x SUPPORT_XORG=1  install
option.

When boot the board i am getting following error:

[    4.746307] [drm] Initialized drm 1.1.0 20060810
[    4.963867] pvrsrvkm: Unknown symbol drm_pvr_dev_remove (err 0)
[    4.973358] pvrsrvkm: Unknown symbol drm_pvr_dev_add (err 0)
modprobe: 'extra/pvrsrvkm.ko': unknown symbol in module or invalid parameter

I am using AM35x-OMAP35x-LINUX-PSP-04.02.00.07 kernel and Graphics_SDK_setuplinux_4_06_00_03.bin sdk. And also in the release note i have seen that X11 is supported.

Please help me in this regard.

Thanks,

prabha

Hi Prathap,

pvrsrvkm: Unknown symbol drm_pvr_dev_remove (err 0) issue is solved. But i am getting some other error as given below:

(==) pvr(0): DPMS enabled
(==) pvr(0): Direct rendering enabled
(EE) pvr(0): PVRDisplayCommandNoArgs: drmCommandWrite failed (-22)
(EE) pvr(0): PVRDisplayScreenInitFinalize: PVRDisplayCommandNoArgs failed (-22)

EndSection.

But i am not getting any display in my HDMI port.

Please find the attachment of config file,xorg.conf and xlog for your reference.

Thanks and regards,

Hi Prabha,

Good to know that you were able to solve the commonly encountered problems by following the sgxdbg instructions.

From your logs(xlog.txt), its clear that the 3D demo is running. No issues with SGX or Xorg driiver from the logs you provided.

Can you check if the HDMI display is working fine on that board by running any fbdev unit test application?

I am providing some check points for cross checking/reference. These are also present in the user guide.

* To check if system is fine/ready to run X apps, make sure you see the log 
(==) pvr(0): Direct rendering enabled 
on running the omap-demo script (This is there in the logs you provided).

* Also check lsmod. It should show the output as below(2 modules inserted successfully)-
# lsmod
Module                  Size  Used by
pvrsrvkm              165296  2
drm                   128254  3 pvrsrvkm

* Also check if X is running - issue ps -eaf command on the board and make sure X is running -
root      2136     1  1 07:47 tty2     00:00:05 /usr/local/XSGX/bin/X -verbose 
If its not running then drm module might not have inserted properly. In this case issue depmod -a command on the board Linux command prompt and reboot the board. 
Once the board comes up, run the omap-demo script. 

* Now issue following commands -
export LD_LIBRARY_PATH=/usr/local/XSGX/lib
export DISPLAY=:0

* Check xorg.conf to be present under /usr/local/XSGX/etc

 * Now the system is ready to run any X-app. One can run unit test application as shown -
# /usr/local/XSGX/bin/glxgears
193 frames in 5.0 seconds = 38.411 FPS
192 frames in 5.0 seconds = 38.355 FPS
193 frames in 5.0 seconds = 38.428 FPS

You can also check by issuing cat /proc/interrupts. This should show SGX interrupts increasing continously when running any 3D demo or unit test app.
If you see all the above points are fine, then first make sure that the HDMI display is working fine on that board by running any framebuffer (fbdev) application.

Thanks,

Prathap.

Hi Prathap,

I followed all the steps you have mentioned.

I ran the default image came with the board. With that image i verified that HDMI display is working fine. I ran framebuffer application also.

But with the framebuffer application i am not getting any display.

But in the minicom i can see only

The framebuffer device was opened successfully.
1024x768, 16bpp
The framebuffer device was mapped to memory successfully.

Hi Prabha,

Thanks for the info. Need some clarification.

Are you mentioning that you are able to get the HDMI display working fine with standalone framebuffer application using the uImage that came with the board but not with the uImage you built? If so what is the difference between the 2 images? Are you building the kernel with defconfig? Can you check if the frame buffer/HDMI display is enabled in your kernel build through menuconfig?

As i mentioned earlier this is not a SGX problem. You need to get the standalone framebuffer HDMI display working fine first & then only try running SGX apps.

In this case, please raise a separate query/issue mentioning that you are not able to get the frame buffer HDMI display working on your board so that the frame buffer driver experts can take a look & provide you the right pointers.

Thanks,

Prathap.

Hi Pratap,

i ran the frame buffer application from minicom. Is that correct? i rechecked my config with the default image .

As you can see from the below log Frame buffer is enabled:

To which mailing list i have to raise this query? and can you tell me how to test the standalone Frame buffer application?

Regards,

prabha

Hi Prabha,

Your observation so far is that the frame buffer HDMI display works fine with prebuilt uImage and does not work with the uImage you have built right?

As mentioned earlier , you can try running SGX apps only after you confirm that the standalone framebuffer HDMI display is working fine using any frame buffer sample or test application that you know to be working fine.

If you are seeing issues with the standalone framebuffer sample or test application itself or want to get more details on it, please raise it as a separate query/issue in the same forum just like the one you have raised on SGX.  This will grab the attention of frame buffer driver experts & can help you to get right pointers.

Thanks,

Prathap.

Sorry for this late  intrusion,

You say you have managed to operate a Beagle xm Rev C board using the TI AM35x-OMAP35x-LINUX-PSP-04.02.00.07. May I ask how you managed this? We have tried the stock PSP and it does not work/recognise the xM Rev C board. Looking at the specific code, x-load, u-boot etc, it only seems to support the original xM release and not the Rev C.

Any Guideance on how to get the PSP to work with a xM Rev C board would be very kusc appreciated.

Hi Prathap,

pvrsrvkm: Unknown symbol drm_pvr_dev_remove (err 0) issue is solved. But i am getting some other error as given below:

 

Gidday Prabha,

Did you resolve the bus error issue when trying to read the SGX version? What extra steps did you need to do to turn on the SGX?

Thanks in advance

Joshua
