i.MX6: KGDB is not working on cross UART

[dharani_r]

Dear All,

             I am trying to debug the kernel with GDB based on below steps.

Boot arguments:

setenv bootargs console=ttymxc1,115200 kgdbwait kgdboc=ttymxc0,115200 root=/dev/nfs nfsroot=<ServerIP>:/nfs-setup/rfs ip=<Target-IP>::<Gateway-IP>:<Netmask-IP>:iMX6:eth0:off rw rootwait

After board boots, the kernel entering in to GDB to debug the kernel as:

imx-sdma 20ec000.sdma: initialized

Serial: IMX driver

2020000.serial: ttymxc0 at MMIO 0x2020000 (irq = 58) is a IMX

21e8000.serial: ttymxc1 at MMIO 0x21e8000 (irq = 59) is a IMX

console [ttymxc1] enabled

When I run the vmlinux from host, I get the below error:

(gdb) target remote /dev/ttyUSB1

Remote debugging using /dev/ttyUSB1

Ignoring packet error, continuing...

warning: unrecognized item "timeout" in "qSupported" response

Ignoring packet error, continuing...

Ignoring packet error, continuing...

Bogus trace status reply from target: timeout

If I use the same UART port for both console and KGDBOC, I could debug the kernel based on below arguments

setenv bootargs console=ttymxc1,115200 kgdbwait kgdboc=ttymxc1,115200 root=/dev/nfs nfsroot=<ServerIP>:/nfs-setup/rfs ip=<Target-IP>::<Gateway-IP>:<Netmask-IP>:iMX6:eth0:off rw rootwait

and

(gdb) target remote /dev/ttyUSB0

Why can't I debug the kernel, when I use one UART for console and another UART for kgdboc?

Hi,

probably your problem is the same as in this other thread:

Kgdbwait into wait state, but GDB timeout, can not connect

Basically, kernels prior to 3.19 do not enable UART clocks until the serial port is enabled. As the second UART was only used for KGDB, that tty was off and thus the clocks never properly set-up.

Try a newer kernel, or applying the patches I refer on that other thread, and it should work.

Please look at my comments below.

In Freescale BSP all the UART ports can be accessed through the device files
/dev/ttymxc0 through /dev/ttymxcX (where X is the maximum UART number supported
by the IC).  /dev/ttymxc0 refers to UART 1.

To use several UART ports it is needed to configure them , in particular corresponding
pins should set via the IOMUXC. Also UARTs should be enabled in Linux kernel.  

Please look at “Registering a New UART Driver” chapter “i.MX_6_BSP_Porting_Guide.pdf”.

In Yocto release many board specific configuration options for the driver are set in Device Tree

file(s).

Have a great day,
Yuri

I have on i.mx6 dual question too~

~# echo g > /proc/sysrq-trigger work good

but  Kgdbwait into wait state, but GDB can not connect

of course I exit the mincom~ also try to use

git://git.kernel.org/pub/scm/utils/kernel/kgdb/agent-proxy.git

still can not work
