【驱动】Orin NX恢复备份失败：does not match the current board you‘re flashing onto

1、问题描述

更新NVIDIA的sdkmanager后，备份了新版的Orin NX（支持super模式，150T算力）的镜像；
在旧版本的Orin NX上使用前面备份的镜像，重新恢复系统时，没有烧写成功，报错：

nvrestore_partitions.sh: Use the default nvpartitionmap.txt as the index file.
nvrestore_partitions.sh: You are trying to flash images from a board model that does not match the current board you're flashing onto.

2、原因分析

1）打印备份镜像的板子型号和当前将要恢复的板子型号
修改文件：tools/backup_restore/nvrestore_partitions.sh
添加打印：echo “FIELDS[2] = ${FIELDS[2]}, BOARD_SPEC = ${BOARD_SPEC}”
修改后的内容如下&#x
