Is this starting up for you?

Hey nice work, I'm trying to get this working as well so I can startup the MMU on rpi4, it doesn't seem to startup for me though.

I tried downloading the firmware from today and from ~6 months ago but neither will boot up for me.

I'm able to get the MMU working on the rpi 3 but not the 4, so was hoping to be able to boot this up and use some of your code.

Hello Mr. LLD!

I've tried using the latest firmware and everything worked fine.

Did your rpi4 show the firmware messages or there's nothing at all? The firmware messages are:

Initialising SDRAM ...
...
Starting start4.elf @ 0xfec00200

Also if you didn't hook up the pl011 UART it may take ~15 seconds for the parent/child messages to start showing on the mini-uart because there're a lot of debugging messages printing on the pl011 UART first.

I've also DM'ed you on discord, if you'd like to chat there.
