Bricked the MiSTer?

[misterrocks]

I bought a MiSTer Pre-configured Bundle in January 2022 and sadly am just now getting around to playing with it. I tried to use the Downloader script to update it but it said that my software is older than September 2021 so I would need to follow the instructions here to update it:

https://github.com/MiSTer-devel/mr-fusion

I downloaded and unzipped the image and used the following command to copy it to the SD card which completed without error:

dd if=mr-fusion-v2.7.img of=/dev/sdb status=progress

I booted the MiSTer with the card inserted and I got the blue screen and splash screen as expected but nothing from the system after that. After rebooting I don't get the blue screen and splash screen any more. Does anyone know what went wrong or how to fix it?

I don't think you bricked it, I would just start over and use balenaEtcher this time instead of straight dd.

Is there a dd command that works?

Try a sync after dd.

[misterrocks]

You were right. Not bricked. I got it working by using Gnome Disks instead of dd to flash the SD card image. Still interested to know a good dd command in case anybody has seen one.

it's pretty much impossible to brick a MiSTer. Worst case scenereo, you have to copy your saves to a pc and reflash your sd card.

dd works just fine, but it often returns before it's really done. You really should give a sync command afterwards. It also helps to set a sensibly large block size for the command. I usually go with bs=1m for SD cards. Limits the number of write operations performed. So:

Code: Select all

dd if=./imagefile.img of=/dev/sdb bs=1M ; sync

That should do it. Replace /dev/sdb with your actual SD card's block device. I'm on FreeBSD myself so the M after 1M may need to be lower case in Linux, not sure off the top of my head. Consult the man page. The sync command itself should work.

I am having the same issue as OP. Bought a MiSTer years ago and never used it. Trying to use it now and getting the "update OS" message. How do I update the OS?
