Dear Team,

I am using i.mx6sololite processor for our epos terminal. My question is can i use older version of uboot (NO device tree support i..e. 2009.08 uboot) wth newer version of kernel (i..e 3.10 kernel).what are the changes i need to todo .

and one more thing is i want to load kernel and dtb file combined .kindly let me know the memory locations changes for uImage loading (3.10 kernel ) with out dtb file loading separately.

I have prepared uImage along with dtb but my kernel stucks at starting kernel....and not proceeding further.

so i doubt my uboot environment he am attaching my uboot related stuff.

bootdelay=1
baudrate=115200
loadaddr=0x80800000
rd_loadaddr=0x81000000
netdev=eth0
ethprime=FEC0
uboot=u-boot.bin
kernel=uImage
nfsroot=/opt/eldk/arm
bootargs_base=setenv bootargs console=ttymxc0,115200
bootargs_nfs=setenv bootargs ${bootargs} root=/dev/nfs ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp
bootcmd_net=run bootargs_base bootargs_nfs; tftpboot ${loadaddr} ${kernel}; bootm;
bootargs_mmc=setenv bootargs ${bootargs} root=/dev/mmcblk0p1 rootwait quiet
bootcmd_mmc=run bootargs_base bootargs_mmc; mmc dev 1; mmc read ${loadaddr} 0x800 0x4000; mmc read 0x98000000 0x4A00 0x12C; bootm
bootcmd=run bootcmd_mmc
bootdelay=1
ethact=FEC0
ver=GL11-UB-2009.08-1173-1.0.bin (Jun 14 2016 - 15:34:52)
first_boot=1
boot_fdt=no
filesize=5164C9
fileaddr=80800000
ipaddr=192.168.2.39

and am stucking at

bootm
## Booting kernel from Legacy Image at 80800000 ...
