hi Guo:
  I guess CONFIG_ARM_APPENDED_DTB and CONFIG_ARM_ATAG_DTB_COMPAT are ARM
soc specific?
  So, what if I want to boot MIPS kernel, but without bootloader support DT?
  Thanks

Dennis

&gt; Hi,<br>
&gt;<br>
&gt; My U-boot is on an older version and that doesn&#39;t have DT support =
for ARM.<br>
&gt; Now, is there any way of booting Linux with DT, without U-Boot support=

&gt;<br>
</div>This is how I responded to Fabio on the same query a few hours ago :)=
<br>
<br>
- Turn on CONFIG_ARM_APPENDED_DTB and CONFIG_ARM_ATAG_DTB_COMPAT<br>
- cat zImage mx27pdk.dtb &gt; zImage_dtb<br>
- Boot zImage_dtb as you do with zImage<br>
