MNT ZZ9000 and Linux

rjnorthrow · 22 July 2021, 14:28

I wonder if someone can help me get this going. I have an A4000D with MNT ZZ9000 card and I want to run linux to test the memory on the card to rule out problems with my Amiga or the ZZ9000. I have run Amiga Test Kit and the memory test fails.

So far I have followed the instructions at https://source.mnt.re/amiga/zz9000-l...p19a/README.md and connected up the ZZ9000 to my laptop via a serial to USB cable so that I can see the output from the ZZ9000.

Here is the output:

I have deliberately not connected the Ethernet as I want it to boot from the SD card.

Can anyone tell me what I am doing wrong here? Thanks!

I need to figure out where I can add the linux kernel command line options such as 'root=/dev/mmcblk0p2'

rjnorthrow · 22 July 2021, 20:25

OK, found it:

setenv bootargs 'root=/dev/mmcblk0p2'

rjnorthrow · 22 July 2021, 20:27

See details in the thread

stevelord · 22 July 2021, 22:11

Are you having weird crashes with your ZZ9000? Random memory bugs?

I ask because I've had the same thing and have been convinced I've been going mad. In OS 3.2 I'm getting gurus from requesters amongst other things.

I've found lowering resolution helps (and speeds things up massively), but that's about it. I'd be interested in seeing how you get on with the linux side. I'll have a go at repeating it, maybe we can compare notes?

rjnorthrow · 23 July 2021, 09:32

Yes, although it sounds like I'm having more serious problems as I can't even get an RTG screen up at all! The test screens from Prefs are either corrupted, show nothing, crash or reboot the Amiga

After running the X server on the linux side, I get the same problem in that I get a screen but it's corrupted and the mouse leaves trails behind it

I'm not sure if this points to bad hardware or software, that's what I'm trying to find out

To complicate things, I have a Cyberstorm Mk II with 68060

One thing to try straightaway is to run the ZZTop application and do the Bus Test. You should get no errors from that

If you need help from the linux side, I'm happy to help

stevelord Registered User Join Date: Apr 2019 Location: UK Posts: 540	Are you having weird crashes with your ZZ9000? Random memory bugs? I ask because I've had the same thing and have been convinced I've been going mad. In OS 3.2 I'm getting gurus from requesters amongst other things. I've found lowering resolution helps (and speeds things up massively), but that's about it. I'd be interested in seeing how you get on with the linux side. I'll have a go at repeating it, maybe we can compare notes?

rjnorthrow Registered User Join Date: Jul 2021 Location: Brighton, UK Posts: 31	Yes, although it sounds like I'm having more serious problems as I can't even get an RTG screen up at all! The test screens from Prefs are either corrupted, show nothing, crash or reboot the Amiga After running the X server on the linux side, I get the same problem in that I get a screen but it's corrupted and the mouse leaves trails behind it I'm not sure if this points to bad hardware or software, that's what I'm trying to find out To complicate things, I have a Cyberstorm Mk II with 68060 One thing to try straightaway is to run the ZZTop application and do the Bus Test. You should get no errors from that If you need help from the linux side, I'm happy to help
