Linux: Failed to boot from nfs with am335x board. ti-processor-sdk-linux-am335x-evm-05.02.00.10

Hi,

Could you please capture the entire boot log and attach it as a file to your post? I'm sorry, the screen captures are lacking too much information and are too hard to read in order to be able to provide good help.

Thank you.

Hi!

Thank you for reply!

After some probe and debug, I have some new information:

I've turn on the NAND_DEBUG，and the boot log is the following:

I boot from nand and tried to mount nfs filesystem, failed: svc: failed to register lockdv1 RPC service (errno 111).

Then I searched the web, it told me to add a "nolock" option. It did work!

But there is nolock option in the kernel parameter u-boot provided. so puzzled.

Thank you very much!

Hi,

Just checking in to see if you've found a solution to this problem? If not, can you provide an update on your current status?

Thanks.

Hi, 

I have not found any solution yet, and the status is just remained. As a workaround I've flashed the images into nand and boot from it. Then mount nfs file system after linux is up. That works for application development.

If you have any ideal, please let me known.

Thank you very much.
