"scsi_accel_rp2040_finishRead timeout" with any SD card

[sozonnyk]

I'm getting scsi_accel_rp2040_finishRead timeout with any SD card.
I tried SanDisk Ultra 64Gb Class 10 and then SanDisk Extreme 64Gb V30
Both cards are brand new and formatted using SD Formatter.
I also tried several different images which work fine on PiSCSI but no luck with BlueSCSI.
Same log with any card or image.
Can someone please help me?

Computer: Macintosh Plus.

This is due to you having Debug enabled on the Mac Plus (see Compatibility page for more info) Simplify your ini to just

[SCSI]
System=MacPlus

And you should be good.

[sozonnyk]

Thank you @erichelgeson
It indeed was a problem.
I think I missed it because I thought that sentence means that debug is not going to work, not the whole thing.
it would be great to modify the Compatibility section to explicitly mention that you wont be able to boot on Mac Plus if Debug is set to true.

[erichelgeson]

Please feel free to update the wiki if it could be more clear, glad you got it working!
