Uart problems in am335x

Other Parts Discussed in Thread: AM3354

Hi,

I am using my uarts (ttyO1, ttyO2, ttyO0, ttyUSB1) using in my am3354 platform and customized drivers in sdk6 Linux 3.2 is working good. When I am using the same uarts in Linux 3.12 sdk7 is giving many issues. Some times the ports are detecting suddenly and stop, some times if I access one uart and the same time if I am using ttyUSB is giving an issue. Simultaneous data is not coming in all uarts. Could u send me the drivers enable logic for serial ports. In Linux 3.2 I am using only 'omap serial port' and DMA disabled.

Please share the feedback why it is behaving in Linux 3.12. Any patches or modifications required to enable multiple uarts in my am3354.

Regards,

Anil

Hi Anil,

The hw description in kernel 3.2 and kernel 3.12 are different, that is kernel 3.2 uses board file from arch/arm/mach-omap2/ and kernel 3.12 uses a device tree file from arch/arm/boot/dts/.

So first of all make sure you have your device tree file set accordingly. The correct setup of dts file enables your uarts & calls the appropriate kernel drivers.

Kernel 3.12 also uses the omap-serial driver, but there have been some changes since 3.2 you can use a diff tool to track the differences between the two versions of the driver (in kernel 3.2 & kernel 3.12). I suggest you integrate your modifications in the 3.12 drivers, and not just replace the existing sources in kernel 3.12 with your customized uart drivers.

Hope this helps.

Best Regards,
Yordan

Hi Yordan,

I ma referring the same device tree in Linux 3.12, Please find attached dts file which have declared the definition for all the peripherals.

Also please suggest me the tools for seeing the difference between the 3.2 & 3.12

Regards,

Anil.

Hi Anil,

anil kumar23 said:
Also please suggest me the tools for seeing the difference between the 3.2 & 3.12

Personally I use Meld on my Ubuntu host, to compare driver sources.

I will have a look at the dts & post if I find anything wrong with the setup.

Best Regards,

Yordan

Hi Yordan,

Can you give me the standard configuration file for Linux 3.12 for compiling all the drivers.

Regards,
Anil

TI__Guru**** 161600 points

Hi,

It is available in the sdk. For SDK7.0 it is arch/arm/configs/tisdk_am335x-evm_defconfig.

Hi Yordan,

the same thing i have done, but my Qt applications are not syncing, mean it is running my application then if i click and go in to the next widget it is not allowing. there is a issue to pop up next window. It is not going in to the next widget. it is coming next widget executed and staying in previous widget.

Recently i have changed some drivers in in my menu config and disturbed the whole kernel tree. If i put my old zImage & am335x-evm.dtb and run from sdcard it is working normal. To revert my changes, i need to recover my drivers in menu config. previously I have changed some settings in DMA and under USB drivers.

Regards
Anil

Hi Yordan,

Is it prefer to use

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tisdk_am335x-evm_defconfig

or

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- omap2plus_defconfig

which one i need to execute the configuration to my am3354 platform.

Regards,
Anil

Hi,

The tisdk_am335x-evm_defconfig should be used, when building the SDK7.0 kernel for AM335x devices.
