Apalis iMX6 # run setupdate

Easiest would be to use the Toradex Easy Installer to perform the recovery as it will automatically take care of any details.

Hi Marcel.
I’m using “Apalis-iMX6_ToradexEasyInstaller_1.3-20171201”. I run the below command “recovery-linux.sh” and it say it done successfully.

ubuntu:~/Aravinth/Apalis-iMX6_ToradexEasyInstaller_1.3-20171201$ sudo ./recovery-linux.sh 
Downloading Toradex Easy Installer...
Successfully downloaded Toradex Easy Installer.

ubuntu:~/Aravinth/Apalis-iMX6_ToradexEasyInstaller_1.3-20171201$

But after restarting I’m noting any log.?

After the Successfully downloaded Toradex Easy Installer. message the Toradex Easy Installer UI should be starting on your target showing on any connected display (e.g. HDMI or parallel RGB). You may then interactively (e.g. using a USB keyboard or mouse also connected to Ixora) install images or prepare an SD card or USB stick with an image for unattended automatic installation.

The big question is what exact versions of things you are talking about. Later BSPs make use of an U-Boot SPL to configure for IT vs. non-IT modules while earlier BSPs required separate binaries therefore the run update vs. run update_it. As you mentioned using the IT SKU you would really need to use the run update_it variant.

7

You are correct. Our board as IT module. In our BSP i didn’t get any image name with IT. So i copy u-boot.img to u-boot.imx-it and I have run the run update_it, but i didn’t get any log after resetting.

But what exact BSP version are you talking about? One can’t just mix and match u-boot.imx u-boot.imx-it and/or the later SPL resp. u-boot.img variants.

Have a look at the following article on our developer website detailing this as well.

U-boot version: V2.7
Branch: 2016.11-toradex

How can i proceed.?

10

But in V2.7 we are using SPL and u-boot.img rather than u-boot.imx resp. u-boot.imx-it. I suspect you are mixing later BSP binaries with earlier update scripts which won’t quite work. Could you please first try with our latest stock BSP 2.7b4. Once that is confirmed working you may go about configuring, compiling and updating your custom U-Boot binary by adhering to above mentioned article.

I’m able to flash “Apalis-iMX6_LXDE-Image_2.7b4” using “Apalis-iMX6_ToradexEasyInstaller_1.3-20171201”. It’s working fine. But “run update_it” with this command it is not working.

12

Sorry, but I would like to stress again that there is no such thing as update_it when using BSP 2.7b4. Please find the following log file of successfully flashing it to an otherwise completely empty eMMC flash.

It’s working now. Thanks for your support.!
