rearranging nand Partitions sizes in uboot unable to boot in imx6ul

[chandraevolute]

Hi,

I have changed the nand partition sizs in uboot mx6ul_14*14_evk.h, attached is my uboot header file

I am able to succesfully run mfg tool and program all the files uboot, kernel, device tree and rootfs to nand.

After changing the mode to internal boot mode it gives error saying wrong zImage magic number. Can anyone suggest what changes need to be done

With the default partition sizes i am able to boot completely. Right now we added some packages to the rootfs and out rootfs increased from 17MB to 62MB.

Hi chandra

#define CONFIG_MFG_NAND_PARTITION means that mfg tools

would use this change, so seems its firmware should be rebuilt, please refer

to attached Yocto Guide sect.6.2 Manufacturing Tool, MFGTool
