When IMX6ULL is powered on , there is no output on the serial console.So i put the board into recovery mode by following the link : iMX Recovery Mode | Toradex Developer Center .
The board boots up , and i use tftp/nfs to load kernel and rootfs.
1 . I follow the link : Colibri iMX7 Firmware Update - Technical Support - Toradex Community ,
to update the u-boot , there are no errors displayed. But , on restarting the board does not boot.
2. The same is the case when i use the ‘run setupdate’ , ‘run update’ commands from u-boot.The steps are a success on restart it does not boot.
3. The same happens when i update the u-boot-nand.imx from the u-boot.
Please let me know if i any additional steps need to be taken care of.
Thank you for the reply.So, i am now trying to replace the whole image via Toradex Easy Installer. As i do not have the easy installer in my board, i download the image from ‘Load Toardex Easy Installer’ section and run recovery-linux.sh on my linux-PC (while the board is in recovery mode). It boots up (i can check in my serial console).
I do not have a display, so i can connect via vncviewer, for which i require an IP, according to the TEZI the IP is ‘192.168.11.1’, which i should be able to check by running the command ‘ip addr show eth0’ (I have USB/otg cable plugged in to the otg port of the board).
But when i run the command in the serial console i do not see the IP address.
Hence unable to connect via vncviewer.
Could you please let me know about what i might be missing.
The interface of RNDIS is called usb0. You can check this with ifconfig. eth0 is the Ethernet Interface which needs Ethernet connection and a proper network setup.
But when i run the command in the serial console i do not see the IP address. Hence unable to connect via vncviewer. Could you please let me know about what i might be missing.
Did you try to connect to the Ip address 192.168.11.1?
yes, i forgot to mention , but i checked with ifconfig as well. I tried connecting to 192.168.11.1 via vncviewer, but it does not connect.
ifconfig does not show usb0.

Welcome to Toradex Easy Installer
This is a Linux based installer for Toradex modules. Currently the
installer does not have a serial console interface. You can use the
Toradex Easy Installer through any of the available display interfaces
using USB mouse/keyboard or via network using VNC. Use:
# ip addr show eth0
to display the Ethernet IP address or use USB RNDIS at IP 192.168.11.1.
/ # ifconfig
eth0 Link encap:Ethernet HWaddr 00:14:2D:00:00:00

You can place a TEZI compatible image to USB flash or SD card and change autoinstall value to true at json file. Than insert this media to your carrier board.and load TEZI. TEZI will automatically flash that image. Please check for more details here.
Could you please let me know the format for the image/folder layout in USB flash?
I downloaded ‘Toradex Embedded Linux Images’ for Colibri IMX6ULL under the ‘OS and demo images tab’ and extracted it to my USB flash.Then I run the TEZI (with autoinstall changed to true in image.json), but its the same output as mentioned above.
I could not find any information related to this.
Format your USB media as FAT32 and unpack this file to a root. Then change a “autoinstall”: false, to “autoinstall”: true,
at /Colibri-iMX6ULL_Console-Image-Tezi_2.8b6.184/image.json
Yes, I believe the MISSING TORADEX CONFIG BLOCK is the culprit. In this case, one would need to recover it first which is usually done using the Toradex Easy Installer GUI. Alternatively, one could try doing this in U-Boot using its cfgblock create command. After that any- and everything should work as usual again (;-p).
