Tool/software: Linux
I use the k2levm(TCI6630).
I haved download the SDK-Linux(ti-processor-sdk-linux-k2l-evm-04.00.00.04) and builded u-boot and kernel.
I used tftp and u-boot succeeded.
I am trying to download a kernel(zimage) to nand in u-boot.
But I do not understand how to load the kernel from nand flash.
I'm following the steps in:
processors.wiki.ti.com/.../Program_EVM_UG
processors.wiki.ti.com/.../Linux_Kernel_Users_Guide
The u-boot environment is as follows.

Question)
1. Why do you need name_mon(skern-k2l.bin)?
2. what is the address to write to nand after loading zimage at 0x82000000?
3. What is bootcmd to load the kernel in nand flash?
