→Rootfs demos using an NFS-TFTP environment for IGEP v2
<br>
You could find these demo on TFTP (Linux kernel:) and NFS (rootfs) exported directories.
* TFTP exported Linux kernels at "/srv/tftp/poky/poky-image-XXXXX/igep0020/uImage" files
<pre>
<br>
* NFS exported rootfs at "/srv/nfs/poky/poky-image-XXXXX/igep0020/" directories
/srv/nfs/poky/poky-image-minimal/igep0020 *(rw,no_root_squash,no_subtree_check,sync)
</pre>
If you want use these demos, IGEPv2 should boot with network TFTP+NFS method.
Let show it:
* 1) Open debug serial port and configure U-Boot environment variables. Press any key when you see:
<pre>
Hit any key to stop autoboot: 5
<pre/>
* 2) Now, you are inside U-Boot prompt. Configure U-Boot environment variables with:
<pre>
U-Boot # setenv project poky-image-sato
U-Boot # setenv machine igep0020
U-Boot # saveenv
Saving Environment to OneNAND...
OneNAND: Saved environment to 0x00200000
U-Boot #
</pre>
All your environment variables should be similar to:
<pre>
U-Boot # printenv
