Nanodlp with Raspberry Pi 4 B

Hello all

I am using Raspberry Pi 3B before with nanodlp build 1693 on sd card, and just upgrade to Raspberry Pi 4 B .
So I mount the latest .img and flash it with build 4209

It runs normally on Pi 3B but when I change the sd card to Pi 4B, it can't run Nanodlp.  How can I fix this?

Thanks

Usually it indicate SD image is old and require os/firmware upgrade to support newer pi versions.

If it is downloaded from nanodlp website, it should work with pi 4 out of the box.
Have you tried pi4 booting with other SD cards?

Re: Nanodlp with Raspberry Pi 4 B

the sd card with latest nanodlp works on raspberry pi 3b
but when i put it on 4b ,it doesn't boot.
I have restored machine setting in nanodlp when it loaded in raspberry pi 3b
Was it related to the machine setting?
Thanks

fixed. upgrade to latest 4400 version
But I think that it was my problem of typing the wrong IP address
