Is this possible to flash firmware by UART?

[greenoaktree]

Hello, Thanks for your works .

I have a reolink RLN8-410(hardware version:N2MB02 or H3MB18) It does not start up successfully after powering up

I can putty to nvr,and this below is the output:

I found the script file did not run when power up.
