SD card not booting in Zero W, in 3B it does

sebar

Dear all,

I have read a lot about interchangeability of SD cards among the several pi models, but as of now have not found a solution for my problem. Apparently this should not pose a problem in most cases, but certain settings in the "config.txt" and "cmdline.txt" (see below) can prevent cards from booting in one model that work in others. But what are they?

Some facts:

Raspbian 9 with retropie (4.14.50-v7+) June 2018
partitions labelled "retropie" ond "boot"

Symptoms:

card works flawlessly in Pi 3B
in Pi Zero W it's stuck at rainbow square boot screen

Why insist on this old System? It contains tweaks, which I am not able to reproduce.

Any ideas?

We don't support 3rd party systems, we don't know how they've been configured and set-up.
Your image has a special kernel, which might as well not work on a Pi 0 if it was optimized for the Pi3 CPU.
