Linux/PROCESSOR-SDK-AM335X: NAND boot giving Bad Linux ARM zImage magic! error

Part Number: PROCESSOR-SDK-AM335X

Tool/software: Linux

Hi,

I am working on the latest TI SDK  ti-processor-sdk-linux-am335x-evm-03.02.00.05.

My NAND boot is working fine when I am writing the images separately.

But when I am creating a full UBIFS image I  am getting

"Bad Linux ARM zImage magic!"  on

"bootz ${loadaddr} - ${fdtaddr}\0"

This is my NANDARGS:

#define NANDARGS \
        "mtdids=" MTDIDS_DEFAULT "\0" \
        "mtdparts=" MTDPARTS_DEFAULT "\0" \
        "nandargs=setenv bootargs console=${console} " \
                "${optargs} " \
                "root=${nandroot} " \
                "rootfstype=${nandrootfstype}\0" \
        "nandroot=ubi0:rootfs rw ubi.mtd=NAND.file-system,2048\0" \
        "nandrootfstype=ubifs rootwait=1\0" \
        "nandboot=echo Booting from nand ...; " \
                "run nandargs; " \
                "nand read ${fdtaddr} NAND.u-boot-spl-os; " \
                "nand read ${loadaddr} NAND.kernel; " \
                "echo error comes now" \
                "bootz ${loadaddr} - ${fdtaddr}\0"

This is the output of my mtdparts

=> mtdparts

device nand0 <nand.0>, # parts = 10
 #: name                                                 size                      offset          mask_flags

 9: NAND.rootfs                                  0x1f500000      0x00b00000      0


active partition: nand0,0 - (NAND.SPL) 0x00020000 @ 0x00000000

Can anyone let me know the issue

Thanks

    Hi,

    How did you set:
    "bootpart=0:2\0" \
    "bootdir=/boot\0" \
    Did you follow this guide:
    processors.wiki.ti.com/.../UBIFS_Support
    for creating and wiring the ubifs into NAND?

    Best Regards,
    Yordan

    I have followed the above NAND user guide for creating and wiring the ubifs into NAND.
