Use recovery mode to load the Toradex Easy Installer
The Toradex Easy Installer (TEZI) is a Linux-based Graphical Operating System Installer to the target. TEZI is shipped with targets from Toradex. If your target doesn't come with the TEZI or you want to flash the new OS, you must reload the TEZI using either USB OTG in recovery mode from an SD card or USB stick using the distro boot mechanism. For more information regarding, see the Toradex Easy Installer page on the Toradex website at https://developer.toradex.com/software/toradex-easy-installer#load-toradex-easy-installer.
The steps below summarize how to use TEZI too to flash an OS image to the Verdin Dahlia carrier target:
- Make sure that there is a USB type C cable connected from the USB DRP port (X3) to your PC.
- Make sure the board is turned off. Make sure that the JP3 jumper is opened
- Press and hold the Recovery Mode Button (SW5).
- Power on the board by pressing the ON/OFF Button (SW3) while keeping the Recovery Mode button pressed for 10 seconds, then release the Recovery Mode Button (SW5).
- Ensure you have connected the board to a display via the HDMI board.
- On the host computer, navigate to the location where you extracted the TEZI installer and run one of the following commands:
- Linux: ./recovery-linux.sh from a terminal
- Windows: recovery-windows.bat from a Command Prompt window
From the serial connection to the target, you'll see the following output:$ ./recovery-linux.sh Downloading Toradex Easy Installer... uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.127-0-g08c58c9 Success 1 Failure 0 1:1 8/ 8 [Done ] FB: done Successfully downloaded Toradex Easy Installer.U-Boot SPL 2020.04-5.7.1+git.33bb8e968332 (Sep 06 2022 - 15:21:33 +0000) DDRINFO: start DRAM init DDRINFO: DRAM rate 4000MTS Training FAILED Quad die, dual rank failed, attempting dual die, single rank configuration.
