SCSI access: SPTI = freeze

[Toni Wilen]

Interesting.. It probably is USB hardware/driver related.

Sometimes mainboards have multiple USB controllers (if it has many ports and single chipset built-in controller can't handle all of them).

If your mainboard has more than one USB controller, could you check if all ports have same problem?

I'll put "emulate audio but use scsi passthrough for everything else"-feature in my todo list. Maybe someday..

"ECHO ON" on Amiga writes "ON" and don't have any function like in MS-DOS. Also "@echo" and "echo." won't work, it will say that it is unknown command. To parse batch you need to write something like "echo SetPatch" before command.

@Tomislav
Sorry, I meant Set ECHO ON of course.

Tested all 5 ports (4 USB-A 3.1 + 1 USB-C 3.1 gen2), nothing changes and still black screen freeze on ASUS GL703GS...
It's also strange that the moment I manually hot-unplug USB drive emu and Win resume from freeze and go on without problems.

WOW! Would be great and make WinUAE even more compatible with some modern HW. Feel free to PM me if you'll need beta-testing of any kind...

Great news:
switched from Verbatim 43888 with Blu Ray UHD 4K support to an Archgon MD-8102P-U3YC-UHDB (AKA: Archgon Star UHD External USB 4K-Ultra HD BD) with Blu Ray UHD 4K support and the freeze issue in SPTI + SCSI scan mode on my ASUS GL730GS is gone!

The funny thing is that both use the same mechanical part: PIONEER BD-RW with the same identical firmware version BDR-UD04 1.11 (18/11/28)!

[Toni Wilen]

This confirms it is the USB adapter that does not handle some drive returned conditions correctly.

(Emulated CD audio in SPTI mode has chance of happening soon.. Maybe.)

[hexaae]

[Toni Wilen]

SPTI mode now internally emulates audio CD commands, any other commands goes to the drive like previously.

There is still something wrong because OS39 CD player refuses to count remaining time but I didn't bother to debug it more today..

[hexaae]

Nice… Just tested and it's like you said for CD Player not showing remaining time… Moreover Eject doesn't seem to work yet.
It's very promising however… Thank you Toni!

[Toni Wilen]

Remaining time works now.

Eject works fine here, it gets passed to the drive like previously. (You did test with previous official version, right?)

[hexaae]

It doesn't work here… and prevents Windows from ejecting the CD right after I quit WinUAE! From Device Manager I see the drive with a yellow mark and says it's not working and an old instance of the driver still unreleased is in memory, till I reboot Windows 10.
In short it looks like Eject cmd in SPTI + scsi command mode screws this drive 'till next Windows OS reboot.

This is what I did:
- genetic species CD
- ran OS3.9 CD audio tool and played a pair of tracks (with timer not working)
- then clicked on eject button in CD audio tool GUI
- then I quit WinUAE and noticed Win 10 refuses to eject drive as well (!)
after Win 10 reboot everything returned to normal behaviour.

[hexaae]

Never mind: latest exe has no issues anymore also with Eject, now!

WOW! That's an amazing achievement Toni! Maybe this time I can even use again (just for retro-emu sake) MakeCD, now testing…

[hexaae]

Ouch… it happened again: after a successful MakeCD session where I created an authentic Mixed Mode CD (!!) eject stopped working, also when I return to Windows 10.

The strange thing is that everything still works fine if I play the CD tracks or boot in WinUAE again… I can use the CD as expected, but eject doesn't work anymore and screwed something with the Windows std driver… I can play audio tracks and inspect CD from Windows as well. Just Eject stops working for some reason… including the eject button on the drive not responding anymore.

Trying to start WinUAE in Log mode. Will attach it as soon as I can reproduce the issue… (looks like a Windows problem to me)

[Toni Wilen]

There is command "PREVENT/ALLOW MEDIUM REMOVAL" which is used by burning software to prevent accidental eject during burning. Perhaps it is still active for some reason.

SPTI mode shouldn't have any other changes, only difference is that it catches any CD audio command (drive won't see them anymore). Audio playback works similar to other CD emulation modes, audio is read normally (using READ CD command which can also read sub channels).

It probably is weird driver/hardware issue, like it is getting re-detected incorrectly or something like that. Probably means some command didn't get any reply in x amount of time and Windows assuming driver/drive being stuck or hung or something.

Perhaps the new drive has other problems..

[hexaae]

Latest build (compiled today in the morning) crashes badly with SPTI + SCSI when I open MakeCD and just examine the destination drive with an empty CDRW inside…

[Toni Wilen]

Only difference should be a bit more logging.

Does it also happen if logging is not enabled? (no -scsilog)

[hexaae]

Tried without "-scsilog -scsiemulog" and still crashed.
Crashes also with log disabled:

[Toni Wilen]

Did you have some CD player running in the background?

Crash according to log happens in READ SUB-CHANNEL command which is mainly used by audio players.

[hexaae]

No, and nothing changed since yesterday testing apart the old build…

to have DATA CD icon + MUSIC CD icon automatically on my WB for mixed mode CDs or AudioCDs.

winuae.7z updated, possibly fixes it. Attach dump if it still crashes.
