@yardy In order to update the kernel variant without re-installing the whole SDK, please follow these instructions:
cd <voxl-sdk-release>/system-image # reboot voxl2 into fastboot mode adb reboot bootloader # flash VOXL2 kernel variant 0 fastboot flash boot_a m0054-1-var00.0-kernel.img fastboot flash boot_b m0054-1-var00.0-kernel.img fastboot reboot # OR flash VOXL2 kernel variant 1 fastboot flash boot_a m0054-1-var00.1-kernel.img fastboot flash boot_b m0054-1-var00.1-kernel.img fastboot rebootYou can also test the kernel without overwriting it (the original kernel will be retained after voxl2 reboot:
adb reboot bootloader fastboot boot m0054-1-var00.0-kernel.img # OR fastboot boot m0054-1-var00.1-kernel.imgThe latter method is useful when you are not sure if the kernel you are about to try actually works (when you are experimenting with building your own kernel) - you can try the new kernel without the risk of temporarily bricking your board.
