DM355 driver conflict

Mikhail Smagin

Other Parts Discussed in Thread: THS8200

I have a generic board on DM355 with MT9P031 sensor and DM9000 Ethernet controller on it. I use DVSDK 3.10 with GIT-kernel. I've downloaded the sensor driver and it's latest patch (from here https://patchwork.kernel.org/patch/176222/) and integrated them into the kernel according to the instructions.

The kernel assembled successfully but didn't start. It stucks at the moment of start of the ethernet controller or begins to print some junk symbols on the screen. Without DM9000 driver, as well as without MT9P driver everything starts well.

Have someone faced the same problem? How it can be solved?

Thank you in advance.

Mikhail,

Can you share complete the logs? Without the sensor driver changes is your DM9000 Ethernet driver working fine?

I've discovered that the board starts successfully with both MT9P031 and DM9000 drivers integrated into the kernel if the network cable is not connected. If it's connected, the start-up procedure stucks.

Here is the log of the start-up with network cable connected

Mikhail,

Its more to do with the network. Can you check whether your DHCP server is up and running? Or, try to pass static ip in bootargs and see whether any improvement occurs?

I've tried both cases. The first log, which I've already sent describes the case of static IP.

In the case of DHCP the log is like this:

Mikhail,

What if you keep the cable disconnected and once it boots you reconnect it again. Will get stuck again?

Also can you check whether all the network related configs in kernel defconfig is enabled properly?

I've tried to do, as you advice. If I disconnect network cable during boot-up and than connect it, the board becomes unstable. Sometimes it stucks at the same moment. Sometimes it continues to work, and I can ping it from the host, but can not ping host from the board terminal.

Mikhail,

Can you check the kernel configs, and try disabling few network related settings? I'm not sure about the exact one, but just do a trial and error method. Might help in identifying.

Another experiment to try is, remove the cable and bootup. Run "top" command and then connect the network cable. This will show the processes that are taking high CPU load. This might give more insight as well.

Hi,

I am using same kernel 2.6.32 but i am facing different problem my dm9000 is working fine on u-boot but its not working after kernel is loaded

it can't ping to my host computer what should be the reason

Best Regards

Tejas,

Once you boot up, make run "ifconfig" command. Then run "ifconfig eth0 up" and then run "ifconfig eth0 dhcp"

Hi ,

Thanks for the reply but i have solved the problem by modifying kernel driver there was a issue in reset logic of DM9000 driver

But now i am facing another issue about THS8200 i can't initialize THS8200 driver on my 2.6.32 kernel we are using DM355 evm board. Please guide me

Best Regards

Tejas Dave
