load u-boot to imx6q sabrelite ,but see no output in serial console

[panpanli]

I have both used mfgtool and imx_usb_loader to load u-boot.bin or u-boot.imx to imx6q sabrelite ,but neither works,since I can't see U-Boot launch  on the serial console,and I'm sure the serial console have been correctly setted ,and the boot mode switches have been setted to 00 – Fuses.

here is the output on the terminal of ubuntu 10.04 ,when I use imx_usb_loader to load  u-boot.imx to BD-SL-i.MX6:

pp@pp-desktop:~/imx_usb_loader$ sudo ./imx_usb u-boot.imx

does u-boot load to the board ?if so,why I can't see any output in the serial console?I am so confused,

and I also have used the mfgtool,here is the information in the mfgtool.log:

Panel A Start <CMD/> type="find" body="Recovery" file="" timeout="180" onError="" text="".

it seems the u-boot have been successfully load to the board,does it?but there is neither no output in the serial console, I'm a freshman learning linux,I am eager to get the BD-SL-i.MX6 up,but it seems so many problems there since I can't boot the board,please help me!

Hi,

As far as I know, Nitrogen6_Lite that you use is provided by Boundary Device, not the standard reference board of freescale.So, I'm sorry that I can't reproduce your error.

[panpanli]

thank you all the same!it seems the board has two name imx6q sabrelite and bd-sl...is`t it produced by fresscale and two other companies？ and in fact i need to load ubuntu in the board，and install qt in ubuntu,and i have successfully installed ubuntu in the board,but i don't know how to install qt.is that just as simple as it in pc?can i just use ‘apt-get’ to install qt?

[tonyzheng]

About standard reference board of freescale, pls refer to http://www.freescale.com/webapp/sps/site/taxonomy.jsp?code=IMX6X_SERIES&uc=true&lang_cd=en

You can't install QT only using 'apt-get'. Before installing QT, you should be sure that you hardware supports framebuffer and then install some necessary underlying graphics library. pls refer to http://qt-project.org/doc/qt-5/linux.html

If you are satisfied with the answer, pls close this question and submit correct reply. Thank you.

Regards,

Tony

Hi, panpan

Do you have setup your serial console correctly?

Generally, the setup is 115200,8,NONE,1.

yours,

Hi,TonyI'm sure I have set up the serial console correctly,now I have no idea about why no output in the serial console,can you help me?

Hi,
Can i know where your board boot from?SD/MMC, eMMC4.3, eMMC4.4, eMMC4.41, SATA?

[panpanli]

I 'm not sure,maybe SD/MMC?

[tonyzheng]

hi, I advise you to boot the board from SD/MMC and it is easy!

• Step 1:

Get a u-boot.bin. You can compile it through LTIB or use the standard image provided by Freescale

• Step 2:

Copy the U-Boot image to the SD/MMC card as follows:

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

• Step 3

Insert the SD/MMC card to SD slot and power on the board.Now, you can boot the board from SD/MMC.

you can refer to i.MX_6Dual6Quad_SABRE-SD_Linux_User's_Guide

I have tried this method ,but also failed,since a error came up

[tonyzheng]

Can you provide me more information?And I'm confuesd by you.

Are you sure your board is standard board of freescale? In my opinion, imx_usb_loader is not provided by freescale. It is a script file and you are unnecessary to use it. You can complie a u-boot image through LTIB or Yocto and copy it to SD card by yourself.
