HI,

I was succeffuly build an uImage, now I have a uImage ready at "kernel Dir"/arch/arm/boot/", I think now that the next step it’s to replace the old uImage  by Copying these new uImage in the same location in NFS host directory(/mnt/nfs/boot).

Can’ you please tell to me the steps to do after building these new uImage.

I have the folowing files at "kernel Dir"/arch/arm/boot/" for the new uImage :

    I am not sure I follow; normally you TFTP (as opposed to NFS mount) uImage from your host to your target.  You NFS mount the Linux File-system directory.  This is explained in the corresponding Getting Started Guide for the DaVinci processor you are using (e.g. DM644x, DM355, DM6467, DM365....).

    Per the GSG, when you build your kernel you copy the newly built image from arch/arm/boot to /tftpboot directory (or your default host TFTP directory is different).  This is where your target will look for it when using TFTP service.

    Thanks for your answer,

    I don't know the nexte steps to do after copying the uImage at /tftpboot,

    If there are a document or an article which explain how to Flashing Kernel in NAND in DVM6467.

    Thanks advanced.

    Certainly.  Normally, when you buy our DM6467 EVM, the EVM will include software CDs with the documents and software to get started;  are you using our EVM or the EVM from a third party?  If using our EVM, then you would also get access to the latest DVSDK software for DM6467 where you should find our Getting Started Guide (GSG); this guide covers steps such as how to build kernel, where to copy it, how to configure EVM for TFTP and/or NFS mounting, how to flash new linux kernel....  This is a very comprehensive guide which was written for our DM6467 EVM.
