Jetson Nano Developer Kit 40-Pin Expansion Header Configuration Failed!

Hey guys
I am trying to reconfigure “Jetson Nano Developer Kit 40-Pin Expansion Header” following the document “DA_09565-001” step by step carefully. Everything was ok until I rebooted Nano which was flashed with new u-boot.bin and dtb files. Something seems to be wrong, the u-boot was stopped by some error as follows:

The name of the document “DA_09565-001” is “Jetson Nano Developer Kit 40-Pin Expansion Header Configuration Application Note”, with partnumber “DA_09565-001 | August 2019”

The spreadsheet I was using is “Jetson_Nano_Module_Pinmux_Config_Template.xlsm”, which was download from the follwing url.
https://developer.nvidia.com/embedded/downloads#?tx=$product,jetson_nano

But I modified only one GPIO in the spreadsheet “Jetson_Nano_Module_Pinmux_Config_Template.xlsm” like the following picture.

And there is not other modification to the spreadsheet “Jetson_Nano_Module_Pinmux_Config_Template.xlsm” .
