I want to merge the zImage and dtb files into a single file for writing to SPI flash for easy booting. I have enabled the option, CONFIG_ARM_APPENDED_DTB=y in the kernel config.
After compiling. I merge two files by "cat zImage xxx.dtb > zImage_dtb".
Under u-boot, I types:
setenv autoload no
setenv boot_fdt no
dhcp
run netargs (this set the bootargs)
tftp 0x80060000 zImage_dtb (get from the tftp server)
bootz 0x80060000
After this, the kernel crash, it shows
Kernel image @ 0x80060000 [ 0x000000 - 0x2c13a0 ]
data abort

Resetting CPU ...
What is the correct procedure for this? Are there something need to be enabled in the u-boot code?
