Hi…iam trying to flash kernel permenantly to my board.My kernel version is 4.9.166-2.8.6+gd899927728be…So i downloaded Colibri-IMX6_LXDE-Image_2.8.7 and tried to flash following the methods of flashing…But i cant flash my kernel image . Looks like my uboot is old one . Do i need to flash new uboot to solve the problem or is there any other solution?

The easiest will be to just use the Toradex Easy Installer:

Thanks fory our response.
We installed ‘Toradex Embedded Linux Console Demo (Stable)’ image using easy installer tool, but still we are unable to update our kernel into board.
We need to update our modified kernel on board, SD card port is not working in our board, so only way to update kernel is tftp from uboot.
Copied the required files into tftp directory.
We are unable to find ‘fatwrite’ command in uboot to flash the kernel.
Can you please help us to solve the issue ?

Kernel binary located at UBI partition “kernel”. You can update it directly from Linux using

ubiupdatevol /dev/ubi0_1 <kernel_binary_file>

Or you can do it from U_boot:

  • Load kernel binary from network to RAM, then

    # ubi part ubi  
# ubi write <addr_in_RAM> kernel <size in bytes>
