TX1 l4t R28.1 can not flash U-Boot only.


I am trying to modify U-Boot these days. But for l4t R28.1 I can not flash U-Boot only with this command:

sudo ./flash.sh -k EBT jetson-tx1 mmcblk0p1

The log shows that flashed successfully, but the result did not change. And when I flashed the full l4t, the U-Boot result changed, the command is:

sudo ./flash.sh jetson-tx1 mmcblk0p1

Besides, when I used l4t R24.2.1, I can flash U-Boot only with that command.

hello ShayWang,

please refer to https://devtalk.nvidia.com/default/topic/1020778/jetson-tx1/jetpack-3-1-falsh-sh-k-ebt-jetson-tx1-mmcblk0p1-/post/5197337/#5197337

there’s erroneous in the R28.1 documentation.
we should use below commands to update u-boot partition for R28.1/TX1,

$ sudo ./flash.sh –k LNX jetson-tx1 mmcblk0p1
