jetson设备是否可以在系统启动后更新SPI-flash中的UEFI?

我们的一款产品用到了Jetson Orin™ NX核心板,后面会修改UEFI
1、如何在线更新SPI-flash中的UEFI,我看到/dev中好像没有SPI-flash节点?(设备未连接Type-C时)
2、我看到nvme中有一个esp分区,此分区数据是否和SPI flash相同?

Hi qiaowei,

Are you using the devkit or custom board for Orin NX?
UEFI is stored in the partition of QSPI.
If you want to update it only, please try using the following command on your host.

$ sudo ./flash.sh -k A_cpu-bootloader -c bootloader/t186ref/cfg/flash_t234_qspi.xml jetson-orin-nano-devkit nvme0n1p1

Or you can refer to Update and Redundancy — Generating the Capsule Update Payload to udpate bootloader.

不是在PC上连接type-c更新,是在设备中有没有方法更新?

Please refer to the link I shared to perform capsule update for bootloader.
