Hi,

processor:   MX6Q;

Board     :   SabreAI rev.A

BSP:      :   L4.9.11_1.0.0 (Build by myself) 

                     L4.9.11_1.0.0 (Download demo file)

                    L3.14.52 (Download demo file)

I started it with the above configuration.
However, the following error occurred.
How can I solve it?
Is the board broken?

how did you download demo image? which .vbs file you do you use? let me check it

Dear Joan Xie,

Thank you for your reply.

I am not using MFGtool.
I wrote down below.

$ sudo dd if = u-boot.imx of = / dev / sdb bs = 512 seek = 2
$ sync

The board now works once every four times.
Perhaps, I think there is a problem of contact failure.

Best regards,

did you Partitioning the SD card successfully? I couldnt reproduce this issue, maybe you can try to mfgtool, for dd command, don't forget partitioning the SD card and format the card first, and I try the command as below:$ sudo dd if=<U-Boot image> of=/dev/sdx bs=512 seek=2 conv=fsync

Dear Joan Xie,

Thank you for your reply.

The SD card did the following.

$sudo fdisk / dev / sdb
d [repeat this until no partition is reported by the 'p' command]
n [create a new partition]
p [create a primary partition]
1 [the first partition]
20480 [using the default value will create a partition that starts at offset 2048]
102400 [size of the actual partition = 255 MB]
n [create a new partition]
p [create a primary partition]
2 [the second partition]
122800 [using the default value will create a partition that starts at offset 67584]
<enter> [using the default value will create a partition that uses the remaining space on the card]

w [this writes the partition table to the medium and fdisk exits]

$sudo mkfs.vfat / dev / sdb1
$sudo mkfs.ext 4 / dev / sdb 2

I think that there is a problem because this board has been purchasing a few years ago.
As new information, L3.10.53 works normally.
I have not solved it, but please close .

Best regards,
Yoshihisa Saito
