Hi,

My U-boot is on an older version and that doesn't have DT support for ARM.
Now, is there any way of booting Linux with DT, without U-Boot supporting DT?

Like, if we can compile dtb somehow with Linux or something else?

This is how I responded to Fabio on the same query a few hours ago :)

- Turn on CONFIG_ARM_APPENDED_DTB and CONFIG_ARM_ATAG_DTB_COMPAT
- cat zImage mx27pdk.dtb > zImage_dtb
- Boot zImage_dtb as you do with zImage

Regards,
Shawn

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

Yes, see CONFIG_ARM_APPENDED_DTB and CONFIG_ARM_ATAG_DTB_COMPAT.
