UART load issue in am335x

anil kumar23

Other Parts Discussed in Thread: AM3352, AM3357, AM3356, AM3354, AM3359, AM3358

Hi,

I am continuously reading data from UART and displaying in my application using Linux 3.12 with Qt 4.8.4.

after a period of time my CPU load is reaching it to 90-100%. then my Qt application is hangs and my cursor movement is very very slow.

why is there any serial driver setting are making any issue, any patches. I have enabled only OMAP serial port support (Device Drivers ---> Character devices ---> Serial drivers ---> ).

I have enabled the serial driver settings in my menuconfig, Find the below settings with snapshot.

How to reduce my CPU load and to improve my system using UARt related application. It is only problem when i tried to read the data from UART based only is giving issue..

Regards,

Anil

Hi,

Which AM335x device are you using: AM3352, AM3354, AM3356, AM3357, AM3358 or AM3359?

Have in mind that your device may not have a GPU integrated in the SoC. In this case I recommend checking your environment with (ps, top or valgrind) to see if you have any memory leaks in your gui applications. If you've made any modifications to the kernel, it may also be a good idea to enable the kernel memory leak detector.

If your device has GPU, then see if you've enabled the graphics support in your kernel (that is the graphics sdk component), and again check for any memory leaks in your GUI apps.

Best Regards,
Yordan

Hi,

I am using AM3354 platform and running my system Linux 3.12 (SDK7). Find my ps, top, lsmod status and suggest me where it is going wrong.

Regards,

Anil

Hi Anil,

Your processor does have a GPU & the graphics seem to be utilizing it.

However a single execution of ps or top won't give much info about memory consumption. What happens if you run your QT api on background & then run ps/top? Do you notice increase in memory usage by your application?

As I said valgrind is also useful to track memory leaks in user space applications.

Best Regards,
Yordan

Hi,

This is the case, i run the same application and ported in Linux 3.2 with SDK6 it is nicely running. But when i tried to run in SDK7 with Linux 3.12 with the same application it is giving slow in my qt application.

My app is very slopw and when i see top it is reaching 100% to CPU performance..

I have run my qt app using Valgrind and it is giving the below status.

This issue when i tried to read the data from UART it is giving issue in my application. I am using USB hub from that i have placed CP2102 USB to UART and got the interface as /dev/ttyUSB1.

from this USB1 i am reading the data from GPS.

Still i am facing the same slow issue using my qt apps. I ma not using pvrsrvkm.ko driver in my SDK7 linux 3.12 version.

Because of this pvr, Is there any qt apps are running slow.

Anil

Hi Anil,

Actually you should be using the pvr driver, have a look at the init scripts in /etc/init.d. The driver should be insmoded at boot up. If it doesn't, then this could be the root cause of your qt apps running slow, since qt apps are graphics apps and if gpu is not utilized to offload the arm, it could result in slowing your system.

Yordan

Hi,

I am feeling Linux SDK6 linux 3.2 is good and running apps are nicely. But while i run my apps in SDK7 linux 3.12 is giving very slow and performance is very very poor.

Plz any one look at my issue why it is giving very slow...

Anil

Could you provide the boot logs of your system? Bootlog of your board running SDK7 (kernel 3.12) & bootlog from SDK6 (kernel 3.2), this could give me some additional ideas.

Hi,

I have tried to modify my kernel customization for my board and run in my am335x PVR driver is not running. the below message displays:

Starting thttpd.
[ 28.983105] Unhandled fault: external abort on non-linefetch (0x1018) at 0xb6f8844c
No SGX hardware, not starting PVR

When i tried with prebuilt images (boot & file system) it is successfully loaded the pvr.
Starting thttpd.
Starting PVR

Please let us know how to start PVR driver in my kernel menu config and any configuration required to run PVR.
i am not using any SGX SDK as of now, is it required for this pvr???.

Guide me how to run PVR drivers in my platform.

Regards,
Anil

Hi,

Find attached log, now it seems my system is booted with PVR driver. But sill my qt apps are running very slow in my SDK7.

my qt is 4.8.4 version. which is not configured with Graphics link. Normally i configured qt and created executable and running in our target.

Still Slowness issue is replicating. Qt 4.8.4 is it stable version or any issue. Please suggest me.,

Regards,

Anil

Are you using DDR3? If so you could be running into a problem others have seen. Back in 3.12 and 3.14 there was some contention between the A8 and the M3 that caused a slowdown. See this post http://e2e.ti.com/support/embedded/linux/f/354/p/401863/1434940#pi317016=3. Try out my suggestion where I comment out some code. This has been fixed in newer SDKs.

Hi Steve,

Thanks for your response. I am using DDR2 with 512MB (2*256mb). I am taking am335x evm reference and don't have DDR3.

I am using Linux 3.12 and in my Linux tree under arch/arm/mach-omap2/cpuidle33xx.c mentioned my ddr2 state as below:

struct cpuidle_state am33xx_ddr2_states[] = {
{
.exit_latency = 72,
.target_residency = 150,
.power_usage = 625,
.flags = CPUIDLE_FLAG_TIME_VALID,
.enter = am33xx_enter_idle,
.name = "C0",
.desc = "WFI",
},
{
.exit_latency = 176,
.target_residency = 300,
.power_usage = 562,
.flags = CPUIDLE_FLAG_TIME_VALID | AM33XX_FLAG_MPU_PLL,
.enter = am33xx_enter_idle,
.name = "C1",
.desc = "Bypass MPU PLL",
},
{
.exit_latency = 390,
.target_residency = 500,
.power_usage = 529,
.flags = CPUIDLE_FLAG_TIME_VALID | AM33XX_FLAG_MPU_PLL |
AM33XX_FLAG_SELF_REFRESH,
.enter = am33xx_enter_idle,
.name = "C1+SR",
.desc = "Bypass MPU PLL + DDR SR",
},
};

which one one i need to comment for getting more speed. really i am very disappoint for addressing the problem for slowness in my 3.12.

Please guide me where should i comment?

Regards,
Anil

I've never seen the issue with DDR2. Let's see if this is the same problem as what we saw with DDR3. When your system slows down, can you go to a console and type in

devmem2 0x44e00488

And post the result. If the last few bits are 7, it's not the same problem. If it's 5, it's the same problemSteve K.

Hi Steve,

Please find the results:

root@am335x-evm:~# devmem2 0x44e00488
/dev/mem opened.
Memory mapped at address 0xb6f6c000.
Read at address 0x44E00488 (0xb6f6c488): 0x00000007

based on my reults, Please suggest me

Hi,
One more thing i am using script for reading from tty port with GPS data and stop the script for 5 sec and reading the values and display in the forma of polar plot and tables (%) level are showing in my application. when i am going in this it is hang my system. the same logic i have worked in my 3.2 it is working. i amusing there are also OMAP serial port driver. what could be the reason. is there any graphics related stuff need to compile my apps with openGles.

the slowness is coming when i read the data from UART continuously it is giving system slow

help me how to solve my issue.
regards,
Anil

Hi,

I am using USB to serial port which is /dev/ttyUSB0 port. Is there any issues over usb to serial.

Thanks,

Anil
