flashing tools

banavathvishnu

Hi,
My firefly-rk3288 board has broken when I tried to flash a different bootloader and I have recovered it back flashing recovery image. I could see board boots to android.
BUT when I tried to flash kernel Image (kernel-4.0) that I have built. Although flashing tools says flashing completed successfully but I don't see board uses the kernel Image I flashed. It still uses older kernel that was flashed as part of recovery image.

When rkflashkit tool used
------------------------------
sudo rkflashkit flash @kernel kernel.img reboot

When upgrade_tool used
----------------------------

upgrade_tool di -k kernel.img
Download kernel start...
Download image ok.

Also tried erasing kernel image and I see the same result

does anyone know what would has gone wrong here? Why does board still uses older kernel image?
Thanks
