Hello,

I am using omap-l138 EVM with PSP 03.21.00.04, and I use nfs filesystem. the images of the u-boot and kernel I use are those that given in the image directory of this PSP. The problem is that the startup of the kernel fails when starting the nfs. If I only change the uImage to be from the previous PSP I have used so far (03.20.00.11) everything works well. What is the problem ? Is the nfs filesystem should be different with the new PSP ?

Regards,

Ran
