FX30 custom kernel


#1

Dear,
I recently bought two FX30. I tried to build a custom image to add libraries to the initial one. The build success but I can’t flash it on the FX30. I haven’t any problem to flash the rootfs but when I tried to flash the kernel, the kernel’s part seem staying empty : the FX30 reboot in bootloader mode.

I managed to boot on my custom kernel by executing the command : “fastboot boot kernel”, the kernel is written in RAM and the FX30 boot correctly but the next reboot will be in bootloader mode. How can I flash the custom kernel definitively ?
Best regards,
