ZuluSCSI RP2040 Initiator Mode - Need help to get it working

[guytaylor]

I am trying to get Initiator Mode working.
My understanding is that it allows the Zulu to image a drive, which is what I would like to do.

I have a full size RP2040, and have the latest firmware installed, v2023.07.01 and the drive is a Quantum Fireball SE (which was an a Yamaha A3000 sampler)
The drive was working fine in the sampler. The drive SCSI ID is 0

What I have tried is, connecting the ZuluSCSI directly to the drive using a 50 pin cable, and powering both.
I set the 'Initiator' jumper on the Zulu as well as the debug out.

But I can't get it to see the drive. I tried all 4 combos of SCSI termination, and here are the logs.
I wait for 60 seconds for each run, and the logs just repeat, I trimmed the log output as they just are repeating

Any tips to what I may be doing wrong?

@guytaylor how are you powering the Fireball SE? Each device should have termination enabled.

[guytaylor]

SCSI ID = 0 on the drive.
I tried 3 different cables (One of them was the one that was being used in the sampler and worked)

[guytaylor]

how are you powering the Fireball SE?

I am using the power from the A3000 sampler (this is what powered it when it was in the sampler) and I am power the Zulu off the floppy power cable

[guytaylor]

I have a 2nd Zulu, I tried that, same behavior (older firmware Dec 2022)
I also put the SCSI drive back into the A3000 to confirm it still works, and that read it fine

[aperezbios]

@guytaylor thanks. What's the exact model number on the hard drive? I may have one here I can attempt to replicate with.

[guytaylor]

Great, thanks @aperezbios Appreciate the help! :)

The details are:

On the main sticker:

Quantum Fireball SE
3.5 Series
N143
Model Number: 2.1S, 3.2S, 4.3S, 6.4S, 8.4S

On the sticker on the connector:
4.3 S P/N SE43S012 Rev 01-B

[aperezbios]

@guytaylor I'm able to replicate this behavior while attempting to dump a 1.2GB Quantum Fireball, model 655-0394, with my ZuluSCSI. Other Quantum drives I tested worked fine, so this seems like some sort of possible/likely bug.

[guytaylor]

Thanks for doing that. :)

[aperezbios]

@guytaylor I think we finally have a fix. It works for me with the 1.2GB Quantum Fireball I mentioned above, , but I'd like to have you test it as well, if you are able to do so.

All you need to do is download the attached .bin file, unzip it, and put it on the ZuluSCSI's SD card. At power up, it should detect the .bin file (only if it's decompressed) and re-flash itself, then reboot.
