What does U-Boot's "Unknown command 'boot i'" mean???

[sangjinhong]

I uploaded L3.0.35_4.1.0_130816_images_MX6/u-boot-mx6q-sabresd.bin,

L3.0.35_4.1.0_130816_images_MX6/uImage

and L3.0.35_4.1.0_130816_images_MX6/rootfs.ext2.gz

to i.MX 6Dual/6Quad SABRE-SD board.

However U-Boot halted and The error message is "Unknown command 'boot i'"

I don't know why!!!

Please, help me!!!

[AnsonHuang]

Can you paste your uboot command line setting? Just use "pri" command to get them.

[sangjinhong]

I captured the message of boot sequence and printenv.

Thanks.

“bootcmd=booti mmc2”

This is wrong, uboot try to run bootcmd, it is "booti mmc2", there is no booti command. Try "destroyenv" and reset to use default setting.

[sangjinhong]

Thanks.

But Why is there booti???

[sangjinhong]

I have a different error, and the error message is the following:

The following is the message of error and printenv cmd.

I don't know why there is error like the following!!!

MMC read: dev # 3, block # 2048, count 8192 ... 8192 blocks read: OK

Wrong Image Format for bootm command

ERROR: can't get kernel image!

I'm now following "i.MX 6Dual/6Quad SABRE-SD Linux User's Guide"

and I used the L3.0.35_4.1.0_130816_images_MX6.tar.

I don't understand why I had this problem !!!

[sangjinhong]

I made SD card like the following sequence:

======================================================

$ sudo dd if=u-boot-mx6q-sabresd.bin of=/dev/sdb bs=512 seek=2 skip=2 conv=fsync

$ sudo dd if=uImage of=/dev/sdb bs=512 seek=2048 conv=fsync

$ sudo fdisk /dev/sdb

u<enter>

d<enter>

n<enter>

p<enter>

1<enter>

16384<enter>

w<enter>

$ sudo mkfs.ext3 /dev/sdb1

$ mkdir /home/user/mountpoint

$ sudo mount /dev/sdb1 /home/user/mountpoint

$ gunzip rootfs.ext2.gz

$ sudo mount -o loop -t ext2 rootfs.ext2 /home/user/rootfs

$ cd /home/user/rootfs

$ sudo cp -a * /home/user/mountpoint

$ sudo umount /home/user/mountpoint

[sangjinhong]

"i.MX 6Dual/6Quad SABRE-SD Linux User's Guide" document assumed that SD/MMC card is 4 GB,

but I used 8GB SD Card.

Is that problem???

[sangjinhong · Accepted solution]

I resolved the problem.

I changed u-boot parameter using

i.MX 6Dual/6Quad SABRE-SD Linux User's Guide / 9.2 Running the Image from MMC/SD

U-Boot > setenv loadaddr 0x10800000

U-Boot > setenv bootargs_base 'setenv bootargs console=ttymxc0,115200'

U-Boot > setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/

mmcblk1p1 rootwait rw video=mxcfb1:dev=ldb,LDB-XGA,if=RGB666 video=mxcfb0:dev=hdmi,

1920x1080M@60,if=RGB24'

U-Boot > setenv bootcmd_mmc 'run bootargs_base bootargs_mmc;mmc dev 2;mmc

read ${loadaddr} 0x800 0x2000;bootm'

U-Boot > setenv bootcmd 'run bootcmd_mmc'

U-Boot > saveenv

U-Boot > run bootcmd

[AnsonHuang]

Do you have a kernel uImage in your MMC?!

The error message means there is no valid image.

I followed the "i.MX 6Dual/6Quad SABRE-SD Linux User's Guide" document.

Check the following my answer.

[AnsonHuang]

I don't know, not sure who change it, the default setting should be not booti....
