The problem here is that ZuluSCSI _is not a SCSI2SD device_, nor is it advertised as such. I strongly recommend you read the manual linked above, and email us with any specific questions you may have, after doing so.
I just got a ZuluSCSI Mini in for my Mac Plus but I can't get it to not crash the machine. Both RaSCSI and BlueSCSI images cause the machine to hard reboot. I've tried several settings to no avail. The machine boots off an old SCSI hard drive and loads the entire 4MB of ram without crashing. Blank images don't crash the machine but don't show in OS which is correct I believe.
Can you try with the 6.0.8 image that you can download from https://www.savagetaylor.com/wp-content/uploads/68k_Macintosh/Bootdisks/608_2GB_drive.zip ?
On my Mac Plus, it boots to the Finder, but then the Mac bombs as I try to do almost anything (like just getting “Info about Macintosh” from the Apple menu).
Exact same. About info, immediate illegal instruction. Other apps cause infinite loop system errors.

Happens on my 8500 I was using to set it up, when it actually worked with the sd card I used. It didnt like the 32GB sd card I first used and would sad Mac my 475. The 8500 would start but bomb as soon as it started loading up.
You could try different SD cards?

@frankz seems to have figured this out. It's related to the driver using blind transfers. I'll let him share more, so we're not playing a game of telephone.

Bought one and installed it on an Amiga - it was a 2000 with a GVP A2000HC+8 controller. Worked pretty good!
I made a 3.9GB disk image for use on a 4GB card and it was a bit of trial and error to generate a blank image that made sense because I forgot that disk geometry calculators were a thing.
I'll grab another one to try in a Mac.

Very strange. I installed the zulu board (default dip swiches untouched) in my Mac se/3 (after copying a correctly named and suffixed .hda file) and it worked perfectly... once! Since then, everytime I start my machine (rominator), it doesn't see zulu (with our without an external scsi2sd plugged in, with or without termination dip switch on or off). There is no conflict with scscsi ID's. zulu is 1, others are 3 and 4. What can I do? Do I have to copy the .init fil on zulu card? I already updated the firmware with ZuluSCSIv1_0_2022-05-17-v1.0.2.bin
Do I have to set the dip switch SW1 on ON or OFF?

No txt error log in any case. Also, if I switch termination ON on the zulu and have nothing plugged in the SCSI port of the MAC, the zulu blinks in 5 flash sequence as for "SD card not detected" and an SCSI probe (via rominator) indicates "Bus not terminated". I am very puzzled and disappointed. Otherwise BlueSCSI and SCSI2SD work perfectly.

Please engage with us via e-mail, and _fully_ describe the problem, including which SD card you're using, etc. If you aren't seeing a log, it's because the ZuluSCSI isn't writing one, which almost certainly means it can't find an SD card. Please ensure you're using an SD card that's an SDHC-labeled card. Why are you disappointed, exactly? This thread is not a support forum for every ZuluSCSI customer.

Hello, please apologize my 2 previous posts. First of all, english is not my mother tongue. I may have expressed myself the wrong way and have no hard feelings at all. Also, thank you so much for your e-mail. We will discuss this privately and I'm convinced we'll find a good solution. Again, sorry for any inconvenience. Your product worked perfectly the first time I used it. I may have done a mistake when reformatting the card.

Many thanks and kudos to the Rabbit Hole Computing people for assisting me. ZuluSCSI now works perfectly and my SE30 is happier than ever!

Not sure where you got that (incorrect) memory address from.. The correct syntax/address is:
dfu-util -a 0 --dfuse-address 0x08000000 -D firmware.bin
