i.MX6 ARM cores rarely dead locked when communicated with ttymxc0.

[torus1000]

Hi,

Two ARM cores dead locked during test command input from console continuously.
It happened once per 24 hours. If dead lock happened, watchdog issue the reset.

Have anyone heard of this phenomenon?

What are the possible causes?

Our board info are as following.

kernel: L3.14.38
Board: Prototype board
host OS: Ubuntu14.04 Lemix(linaro14.04)
Serial port: port1(ttymxc0) 115200bps

Anyone can help me?

Thanks

Hello Torus,

Did you check this Errata of the device

https://community.nxp.com/message/397208?commentID=397208#comment-397208 

All the ARM errata has been defined in the arch/arm/Kconfig, you can search from the file arch/arm/Kconfig.

If you want to see which ERRATA enabled on the i.MX6X, please check the .config file after running the build command: ‘make imx6_defconfig ARCH=ARM ….’

Hi Jaime,

I opened new case #00109023 and uploaded register value and system.map.
If you mind, would you reply above case?
