No command "findfdt" in the uboot for ARM core in K2H

Yes, I am using NFS.

For keystone boards , the step will be little bit different.

If you are saying there are some differences, can you help me to find a document or link to illustrate the uboot procedure for K2H evm by using Processor SDK Linux?

What I can find is the procedure for BeagleBone Black Board the in this link ()

Hi Titus

In short, I want to load my recompiled Linux kernel to K2H EVM by using tftp.

First, according to this link (click here), I recompile the Linux kernel, and got two newly generated files: k2hk-evm.dtb and zImage.

Second, I copied those two files to the NFS root folder.

At last, I am following the BeagleBone Black uboot example to setup uboot procedure for K2H EVM. Just like you said, it does not work.

u-boot# env default -a
u-boot# setenv boot net
u-boot# saveenv

I tired what you said. The minicom pops out "init_nfs" is not defined. So I think I need to setup the boot folder, boot file and etc settings to make the boot successful. Can you tell me those things?

I cannot find the TFTP booting procedure in this link.

Hi Titus

I went through the Internet and I program the uboot by the following command.

env default -f -a
saveenv
reset
setenv serverip 10.203.6.199
setenv tftp_root '/home/arrc-3190/ti-processor-sdk-linux-k2hk-evm-02.00.02.11/trainingNFS/boot'
setenv nfs_root '/home/arrc-3190/ti-processor-sdk-linux-k2hk-evm-02.00.02.11/trainingNFS'
setenv name_kern zImage
saveenv
setenv boot net
saveenv
boot

The following is the output of minicom. It shows that there are two 'Access violation' happened. Check the permission of the directory, i.e., 777. The first error is for the file k2-fw-initrd.cpio.gz. However there is no such file in that folder.There are only two file in the root nfs path. One is zImage. Another one is k2hk-evm.dtb. I do not know why the uboot need k2-fw-initrd.cpio.gz.  Second is for the k2hk-evm.dtb, I do believe the file is over there.

It seems like besides zImage and 2hk-evm.dtb, more files needs to put into the tftp boot folder. But what are they?
