I'm working on a var-som-mx6 board with a kernel version 3.0.35. Now I would try to upgrade it to a newer version, for example, using Yocto Dizzy, 3.14.28 kernel version. I find out that with the new version I'll have 4 NAND partition as follows:


0x00000000-0x00200000 : "spl"

0x00200000-0x00400000 : "bootloader"

0x00400000-0x00a00000 : "kernel"

0x00a00000-0x20000000 : "rootfs"


while before I have only 3 partitions (no spl). If I upgrade my NAND writing SPL and u-boot.img via tftp as follows:


tftpboot 0x10800000 SPL

nand erase 0x000000 0x200000

nand write 0x10800000 0x000000 0x200000


tftpboot 0x10800000 u-boot.img

nand erase 0x200000 0x200000

nand write 0x10800000 0x200000 0x200000


it will be ok?

thank you for the attention,

best regards
