LS2085ARDB-Ubuntu

[justindelva]

My question is regarding the the Ubuntu test image for the LS2085ARDB. The document LS2085ARDB_RUNNING_UBUNTU.docx (attached) explains how to set up ubuntu. On page 5, following the instructions on how to configure for an SDCARD boot, I get the error shown here:

=> setenv mmcpart 1

=> setenv bootargs console=ttyS1,115200 root=/dev/mmcblk0${mmcpart} rw rootwait earlycon=uart8250,mmio,0x21c0600,115200

=> setenv boot_call cp.b $kernel_start $kernel_load $kernel_size && bootm a0000000:kernel@1 - a0000000:fdt@1

Wrong Image Format for bootm command

ERROR: can't get kernel image!

Any ideas?

Hello Justin Delva,

In fact page 5 of attached document describes how to boot rootfs filesystem from SD card. It assumes that FIT Images(including Linux, device tree and rfs) has already been deployed on NOR Flash at 0x5_8110_0000.

In the default u-boot environment, variables kernel_start, kernel_load and kernel_size are defined as the following.

kernel_size=0x3000000

kernel_start=0x581100000

kernel_load=0xa0000000

So please program kernel itb image kernel-ls2085ardb.itb onto NOR Flash at 0x5_8110_0000 first.

If your problem remains, please provide the result of "pri" command in u-boot.

Have a great day,
Yiping
