Hi Sir :
I try kernel version 3.2.0 and RT patch patch-3.2-rt10.patch.gz on TI
AM335x EVM(Cortex A8), I find out a problem.
My test steps as below :
1. In pure linux directory, I use zcat ../../patch-3.2-rt10.patch.gz |
patch -p1 command. (pure means I install TI’s SDK : ti-sdk-am335x-evm-
0.6.00.00.00-linux-x86-install.bin without changing anything)
In linux directory :
2. make ARCH=arm CROSS_COMPILE=/home/marcus/ti-sdk-am335x-evm-
06.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin/arm-linux-
gnueabihf- tisdk_am335x-evm_defconfig
3. make ARCH=arm CROSS_COMPILE=/home/marcus/ti-sdk-am335x-evm-
06.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin/arm-linux-
gnueabihf- menuconfig
4. Select kernel Features and preemption Model Fully Preemptible
Kernel(RT)
5. Save .config
6. make ARCH=arm CROSS_COMPILE=/home/marcus/ti-sdk-am335x-evm-
06.00.00.00/linux-devkit/sysroots/i686-arago-linux/usr/bin/arm-linux-
gnueabihf- uImage
7. After building successfully, copy uImage to SD card and power on the
EVM board.
8. Executing iperf -s on linux platform and execute iperf.exe –c
10.0.0.180 –w 100M –t 1200 –I 10 on win 7 platform.
9. Ethernet module on linux platform hangs up.(I can’t ping my PC in
linux platform even though I use ipconfig eth0 down and ipconfig eth0 up
command)
Could you give me some suggestion?
I have tried not to enable RT support and use iperf to test, the testing
result is good.
Best regard,
Marcus

Is there a reason you're not using the latest and greatest 3.2-stable
plust the matching lates -rt patch? Also 3.2 is already old and the
am335x support in mainline is good, so better use a more recent release.

Try a vanilla kernel. Vendor kernel tend to use non-optimal stuff that
stands in your way when you start to do things.

exactly. I remember fixing the driver for v3.8-RT. And v3.2 should have
no support for am335x so there is no way to backport that stuff. Use
something more recent.
