PROCESSOR-SDK-AM65X: PROCESSOR-SDK-AM65X

Part Number: PROCESSOR-SDK-AM65X


Hi ,

SDK Version: ti-processor-sdk-linux-am65xx-evm-06.00.00.07

Sitara AM65XX

I am using default file system  and i am able see all the PHY interfaces enabled using ifconfig(ex:- eth0,eth1....) by default after successfully booting.

But while using  arago-tiny-image-am65xx-evm only ETH0 is detected .

Is there any possibility of enabling two MII(PHY) Ethernet interfaces in Arago tiny file system ??

regards

Venkatesh

    Hi Venkatesh,

    Firstly, the arago tiny filesystem does not include the kernel, modules and some init scripts that are present in the full filesystem (tisdk-rootfs-image). There is a chance that you are missing one of more things from this.

    Could you please check if you have all the dependencies to get all the PHY interfaces working?

    You have to look into the kernel, modules, dependencies and the init scripts - the problem, in my best guess, could lie here.

    Regards

    Hi Karthik ,

    I have prepared a kernel image with required kernel modules and with this image, generated target NFS .Copied entire TargetNFS folder to rootfs of EVM SD card , after booting i can see all the PHY's.

    I didn't change any def-config files used default ones.

    Now the issue is  if I use the same image in arago-base-tisdk-image-am65xx-evm filesystem and copied this filesystem to sdcard  i can see only 2 PHYs  . 

     "You have to look into the kernel, modules, dependencies and the init scripts - the problem, in my best guess, could lie here."

    Can you please provide any references , elaborate dependencies and  init scripts?

    BR

    Hi Venkatesh,

    You can start by comparing the modules that are getting loaded (with respect to the ethernet functionality) and compare between the two filesystems that you have. If you find anything missing, please try to load those modules and see if you can get all the PHYs enumerated.

    Then you can go and look for the script in the default filesystem that takes care of loading this automatically.

    Regards
