ERROR : Flash Jetson Nano : Board ID(3448) version(200)

What does
ERROR : Flash Jetson Nano : Board ID(3448) version(200)
The flash suceeds and the Nano boots.
But I am having problems with other SDK.

What is your error?? I don’t understand your statement.

When I flash the Nano with the SDK Manager

This:

ERROR : Flash Jetson Nano : Board ID(3448) version(200)

appears in the log tab.

What does it mean? The log messages immediately above and below it
are “INFO” messages.

It would be better if you can share the full message…

Does the SDK Manager have a way to copy logs or save them to a file?
Selecting the log on the UI and right mouse down does not
pop up a context menu.

or you could directly go to below path:
~/nvidia/nvidia_sdk/JetPack_4.2_Linux_P3448/Linux_for_Tegra

Put your device into recovery mode and run “sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1”

Will running “sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1” also install jetson SDK components and Additional SDKs?

No, it will not. It only installed the bootloader and driver.
