Hello,

We are designing a SoftWare for the target

Board : i.MX 6 series , Dual Lite , ARM Cortex-A9 Core.

When setting the boot pins to SD on cpu Boot Mode, we are getting terminal:

Observed behavior :  Exception stack ( 0xe4061f90 to 0xe4061fd8 ) as observed in attached image.

also, I have another problem

using Software : DS-5 over Eclipse

I couldn't connect to the target by using USB or Ethernet.

By connecting USB Cable and Ethernet Cable.

Expected behavior : message from Microsoft connecting to the target.

Observed behavior :  there is no message and i couldn't establish connection between computer and Target.

can anyone provide some helps on this?

Thanks in advance!

one can copy full image (without partitioning) please refer to

attached Linux Guide sect.4.3.2 Copying the full SD card image,

or with partitioning using sect.4.3.3 Partitioning the SD/MMC card.

To connect to the target by USB Cable one needs to remove card,

then bootloader falls to Serial Downloader mode, USB OTG port should

be used.

Hi Besho

"Exception stack" error usually is caused by wrong image (for other board)

or ddr errors, please run ddr test for custom board

i.MX6/7 DDR Stress Test Tool V2.20

use FSL Linux BSP (uboot board/freescale/mx6sabresd/mx6solo_4x_mt41j128.cfg

should be changed with new ddr settings found from ddr test)

L3.14.28_1.0.0_iMX6QDLS_BUNDLE (REV L3.14.28_1.0.0)

i.MX 6Quad, i.MX 6Dual, i.MX 6DualLite, i.MX 6Solo Linux Binary Demo Files and Linux BSP Documentation

SABRE Board Reference Design|Freescale

DS5 connection procedure

Thank you For fast response @igorpadykov

my SDCard Was delivered with it's Software.

i set the boot pins to SD on CPU Boot Mode and then i had this exception.

i could't replace this Soft Ware image without formatting this SDCard.

the problem is that i couldn't connect to the target by USB Cable.

the question is :

Should i format SDCard to download the right image by Computer and insert it again to the target to boot correctly and then i can connect to the target correctly .

Am i right?!

Thanks in advance!

sorry for my Questions.

First i downloaded (.sdcard image ) <fsl-image-gui-x11-imx6qdlsolo.sdcard>

and tried to boot from SDCard . i didn't have any message on the terminal or HDMI according booting.

Second i removed SDCard trying to connect to the board by USB OTG and also i couldn't connect to the board.

when you are saying "trying to connect to the board by USB OTG" and "I use DS-5 v5.22.0"

what do you mean ? I think you should use hardware like DSTREAM with DS5

what reference design is based your board ?

it is not possible to answer if package that you have downloaded right or not,

because it is not known what reference design is based your board.

If, for example, it is based on sabrelite - images should be taken from

boundary devices place.
