@AmigaOldskooler

Thanks for the roundup - once again a pleasure to read thru!

Re: ExecSG memory allocation question.

@LiveForIt
I don't know exactly, but API wise AllocMem() pairs with FreeMem() and AllocVec() pairs with FreeVec(). Regardless what you might find by trying it out, I wouldn't consider criss-crossing the pairs a safe path unless it becomes publicly documented in the AutoDocs that its allowed to do so.
Even if it works (which I wouldn't expect it to) the implementation could change and break you library.

So, yeah, I'd say you're stuck with good old deprecated AllocMem().

Re: Usb external hd not mounting

@Antique
Is anything added to the USB log in T: when you attach the harddisk?
Perhaps the HD itself is never being detected by the USB sub system or massstorage driver, or does not respond in a way supported by the USB massstorage driver, and hence never gets picked up by the driver or mounted as a drive.

Re: Infamous Black Amiga Os 4.1 Splash Screen Freeze

@rjd324

The log entry you're pulling forth about USB is probably due to hardware timing. The hub driver tries to be fast, testing port reset after 10ms, but a hardware root hub may take up to 50ms to complete port reset.
What you see is the port reset not being complete after 10ms. Since you don't see any more warnings the port reset has completed within 20ms.

Also, the log entry is the top log entry in the file, which is the oldest log entry of the lot. So this is unlikely to have anything to do with the actual boot lockup you experience.

Re: Why with clib2 proc: requester popup as expected, and with newlib are not ?
Just popping in

@kas1e
as trgswe write, it must be due to the linux path used with chdir().
In AmigaOS terms that means 'folder "proc" in the parent folder' and hence has nothing to do with any volume or assign which DOS needs to request for.

Re: X5000 capacitor fell off ...!!!!!
Just popping in
Just popping in


I don't know it specifically, but it could be a capacitor for stabilizing a power suppply voltage - either as a local stabilisation or stabilizing the output of a DC/DC converter.
Most capacitors in a digital PCB design is for power stabilization and noise reduction, which is probably why your board is still running without it - it's still within specs for normal operation without this one single capacitor. But it may result in the odd trip-up.

Better find a soldering iron and put it back in (and remember to protect against anti static discharge when you do).

Re: AmiUpdate and manual installation of MUI means file requester is using MUI now. Please revert.

@rjd324

Without having been there yet myself, I'd say you should remove, or comment out, the ";BEGIN MUI ASL" to ";END MUI ASL" section in UserStartup so you don't get the PatchASL program run.

Re: MutexAttemptWithSignal
Just popping in

@sTix
Your code _should_ work as you expect and return the signal if that is the reason for MutextAttemptWithSignal() returning, or zero if the mutex is obtained.

How do you trigger with the correct signal? It may be you only posted example code and left out the debug output telling you which signal you have to trigger from the outside, but as it is shown here you can't really see the correct signal to send :)

Disclaimer: I've never used the new mutex function, so I don't know more than what the autodocs and examples indicate.

@devils_advisor
I bought and played thru the game a good while ago without any problems on my SAM460ex. I do believe I bought it via AmiStore as a download.

Have you tried downloading and installing it again? Maybe something went wrong with the archive?

Re: Stack USB 3.0 for OS4 at Pianeta Amiga 2012

@NinjaCyborg
As far as I remember I'm still using the tools from the latest SDK. I don't deal much with the tooling - it's a tool and if it's working and doing what I need I have no need to change it just because a newer version exist :)

I can't speak for other devs - I would believe it varies a great deal, so you'll probably find all sorts of tool chain versions being used.

@NinjaCyborg

With regards to both NDK and GCC/binutils I'm not in the know. The time I have for Amiga related developments I spend on improving the USB area.

@billt
The USB stack should have enough to be able to support USB3. I haven't read up on the USB3 spec in detail, but the basics should be covered. All the nasty work I believe is with the HCD and the hub driver :)

@billt

That is an oversight in updating the usbhcd.doc.
But basically for a device of that speed to be detected by a hub driver will require a USB3 HCD to be driving USB3 hardware (and a USB3-aware hub driver at that).

Neither currently exist for OS4, so what you see traces of is only initial steps to support it in the USB stack itself.

Re: DMA buffer for PCI busmaster headache

@geennaam

I'd say both methods are valid.

What StartDMA()/EndDMA() will add to the game is hiding a bit more of the cache control logic and enabling you to more easily do scatter-gather on non-consecutive physical memory pages.

Good to hear you were able to access the early-startup menu. But bummer about the mouse axis problems.

If I recall correctly you are OS4 beta tester, right? If so, and you are using latest USB modules I'd like to hear more about that mouse of yours - the bootmouse.usbfd should play along nicely if the mouse supports the bootmouse protocol. Otherwise I may have something I need to fix somewhere :)

How about pressing both mouse buttons to get to AmigaOS early-startup menu and select your boot device there? (Once UBoot has finished loading the kickstart modules, that is)

I can't boot my SAM460ex with its on-board SATA enabled either. So you're not alone with that :)

Re: USB does not recognize devices during booting (AOS4 July update)
Just popping in
Just popping in


@rwo

You can see the EndPoint is stalled by the reception of USBERR_STALL (iiirc - don't have the include files here at work :)

You can also issue a GET_STATUS request to the Default Control Pipe (DCP) to get the status of a specific named EndPoint - check the USB spec on standard commands to the DCP for more info - I don't have that spec here at work either.

Btw. I don't know how a device will react to destalling a non-stalled EndPoint. Probably it will behave nicely and take it is a NOP, responding as if it destalled the EndPoint, but I'm not sure.

Thomas

@MigthyMax

I got the same behavior from the July 2007 update.
Reverting to the pre-July 2007 usbsys.device (and, if you want to use USBInspector, that too) fixed it for me - at least as a temporary solution. Dunno why, though.
