Hello Friends,

I have GigE GC2450C Ethernet camera from Alliedvision. connected on Altera SoC Kit (Cyclone V ARM Board)

while trying to chnage the Maximum Packet Size of Camera it always generate an error saying skbuff: skb_over_panic

i am trying to develop an application which grab an image from Camera using Altera SoC Cyclone V ARM board. the Procedure i am followinf is

1. Develop the Code on ubuntu 12.04 and cross compile it for ARM board.

2. Thne Port this Code to ARM board and run on ARM board Using PuTTY.

3. First i detect the Camera presence , the ARM Console (@ PuTTY) show that there is a camera having Serial No and Unique ID etc.

4. Then I open The Camera for Setup. (Please see attached print-Screen)

5. Then I trying to Set the Maximum Packet Size 8228 and run the Code, It Generate an error saying, skbuff: skb_over_panic etc (Please see attached print-Screen)

it seems something goes wrong on arm side.

as the error pont toward arm

Sounds like a problem in the linux kernel code for the relevant ethernet driver an jumbo frames.

This simple solution is not using jumbo frames!

Otherwise first make sure you are using a very recent linux kernel (3.14 or later) and if it still fails try reporting the problem to the 'netdev@vger.kernel.org' list.

Hello Dsl

Thanking you for your support

after typing following command on SoCKit Cansole: uname -r it shows 3.7.0 it seems that my board having alder version of Linux kernel,

so plz help me out how do i upgrade the microSD card for the latest linux Kernel, i have downloaded the latest Stable Kernel Release linux-3.15.4.tar.xz. the only thing is left how to upgrade.

*To get the maximum benefit from as GigE Camera in term of video resolution we need to have Jumbo frames. so i restrict myself on jumbo frame
