I've had that happen when the initial bootup scan is not complete by the time the happy Mac shows up. Perhaps look at disabling the contiguous check with mode=forcefast (if that isn't on already and the image is actually contiguous). That might also be a mode option thing - if not specified the...

I believe that's the INI file failing to load due to FatFS thinking the FAT volume is invalid. I have not documented it well, but on the development branch -DUSE_EXFAT must be specified during compilation or exFAT support will not be included. If it's an exFAT SD card that's like the culprit...

Thanks, I'll add the STL during the next update. I still plan to support all variants of the A3U in the firmware. I've got boards with different sizes of chips as well, and given how difficult its become to find XMegas I'd like to maximize flexibility for anyone who wants to make a copy. For...

I haven't had much time for this project, but I wanted to chime in and say that backplate is awesome! My spouse also got a real kick out of their "scuzzy the snail" art showing showing up on new PCBs. When I do an update on Github I'll add a link to the bracket. As long as @Chopsticks is still...

Hey there! I feel you, I've also been pretty busy with work/life and haven't been on here much, sorry about the delay in responding. As of now, if you want to try out the devel branch and see if things work on your SE/30 that would be awesome. I'm ready to call what's currently on that branch...

I've used optocouplers to do this type of thing before, which also has the nice benefit of isolating the system grounds. That might be overkill: ADB being open-collector, you could also try some tricks with transistors and pull-up resistors. Hopefully not too self-promotional (and Java may not...

I experimented a bit and haven't had a situation where the bootloader overwrites itself (so far): it seems to be OK flashing images repeatedly. A couple things worth trying: If you've used a PDI programmer to flash the application firmware any time after installing the bootloader, by default...

Hmm, that's not good. It makes me concerned that the bootloader is being overwritten somehow. Does it show any signs of allowing you to flash the first file again? It shouldn't care if they are identical. I'll do some checks on my boards too and see if I can replicate this.

That would be a sweet solution. I wonder if it might be useful to the RaSCSI folks too? Some kind of Mac program that could execute commands to list/swap images ought to be useful to any CDROM emulation hardware where there is control over the command set. I have zero experience with Mac...

Thanks! More news: experimental (and I mean experimental) CD-ROM support has been added to the "devel" branch on Github, based on the SCSI2SD implementation. In the config file, define a [hddX] section like normal, but use "type=cdrom" and provide an ISO image as the image. When the system...

After a bit of a break from the project, I'm back with a bootloader. This is generic enough I made a separate project for it, located here: https://github.com/saybur/mcxboot A version tailored for scuznet is also on the main branch under the "bootloader" folder. This bootloader should greatly...

This is an extremely neat bit of work, well done!

The freezing at shutdown seems to be a persistent source of trouble. I think I recall (maybe in the vanished posts) you mentioning some changes made to your branch that addressed that, or a theory on the subject? I haven't been experiencing the issue myself but that may be down to me being...

Good catch, I've only been testing on V1 boards so far. The issue is the lack of a DCLK signal on the V2 boards. I'll get the code fixed this weekend. If you want to try it out in the interim, it will compile fine if you strike "asm_dclk_def," (including the comma) in that line.

This is great, thanks for doing all the work to put this together!
