Tools you need before restoring the image to the eMMC under UBOOT mode.
Tools you need before restoring the image to the eMMC:
- Recovery eMMC image with the UUU burning software:
- A Windows 10 host O/S on a PC (The virtual machine is not suggested to be used)
- USB cable to connect between the host PC and EBOX-IMX8MM. (Ex: USB to micro USB)
- Cable for the console to connect between the host PC and the EBOX-IMX8MM. (Ex: USB to RS-232)
Restore the image to an eMMC.
Write the image to the eMMC on the EBOX-IMX8MM.
This section will introduce how to write the image to the eMMC on the EBOX-IMX8MM step by step.
- Turn on the host PC and unzip the image file in it.
- Connect the host PC and the EBOX-IMX8MM via console cable. (In this case, the console function on the ICOP’s device is on COM2.)
- Connect the USB to micro USB to the host PC, but not connect to EBOX-IMX8MM.
- Open the PUTTY on the host PC and set the Serial line at the correct location. You could find the location under device manager.
If there is no PUTTY on the host PC, please download it on the PUTTY’s website: https://www.putty.org/
- Open a terminal on the host PC and access the location you’ve put the image file and input
“uuu.exe uuu.auto” , and you will see “Wait for known USB Device Appear”.
- Go back to putty, and connect the micro USB to EBOX-IMX8MM to boot it up, and press any key while booting up to access the UBOOT mode and type the command
“fastboot usb0”
- You will see the terminal on the PC starts to restore the image.
- After the restoration is done, you can boot up EBOX-IMX8MM and will see the Yocto working.
