I am stuck in Torizon after installing from Easy Installer. Any tips or suggestions are much appreciated.

I cannot get back to booting the Easy Installer from SD card. I want to get rid of Torizon and install a different image.

What I Did:

  1. installed Angstrom
    LXDE via Easy Installer. This worked fine.
  2. Copied Easy Installer to SD
    Card
  3. Boot Easy Installer from SD card, using u-boot terminal, run distro_bootcmd
  4. Installed Qt Demo image via Easy Installer. Demo worked fine.
  5. Boot Easy Installer from SD cars, using u-boot terminal, run distro_bootcmd
  6. Attempt Install Torizon via Easy Installer.

System hangs at Torizon splash screen after reboot. The Torizon splash screen displays with a static progress-bar or text-entry at bottom (I do not know what it is)

After installing Torizon, attempts to boot from Easy Installer SD card fail:

Using serial terminal connected to X27, press space key, then run distro_bootcmd

I could not seem to get anywhere using iMX Recovery Mode

Any tips or directions are much appreciated.

[Solved] Thank you Raja. All is good.

I wanted to learn about Torizon. I incorrectly assumed iMX6 was a family and it would also work on the IMX6ULL as well. My mistake. I will forget about using Torizon on the IMX6ULL.

With TEZI SD card connected, the following u-boot console command booted into Toradex easy installer (TEZI) and allowed me to download and install other images besides Torizon.

setenv bootm_boot_mode sec
run bootcmd_mmc0

Thank you for your help!

Dear @embeddedEd,

Torizon supported platforms : https://developer.toradex.com/software/torizon#requirements.
Do you really want to use Torizon on IMX6ULL or just you tried on IMX6ULL?

Could you try below u-boot commands with TEZI on SD card

  • setenv bootm_boot_mode sec
  • run bootcmd_mmc0/1

If it is not helping then try below option

Did you try to load TEZI from PC as described here : https://developer.toradex.com/software/toradex-easy-installer#load-toradex-easy-installer

After programming Torizon, I am able to launch TEZI from PC. Please make sure the SD card should not be connected.

If above suggestions not helping you then could you log dmesg and share it with us.

Note: Toradex easy installer is called TEZI.
