./flash.sh -k kernel jetson-tx2 mmcblk0p1 nothing change

Hi Nvidia team,
I modifid kernel for tx2 . Compiling passed and Image and dts replaced in JetPack_4.2.2_Linux_GA_P3310/Linux_for_Tegra/kernel. And then I use the commad “sudo ./flash.sh -k kernel jetson-tx2 mmcblk0p1” like xavier. And then booting, nothing changed,uname -a still old time.
Can you guys help me ? how to flash kernel only?

Could you try with “-r -k kernel”?

Hi ,WayneWWW
Just solved. I found kernel was load from /boot/Image not mmcblk0p26 even it has mmcblk0p26.I think TX2 and xavier is same before. Thanks for your guys help.
