Now it locks the whole machine solid at 50% progress on the "Identifying Drives" dialog. I've only got Wizzo enabled just now (removed ZIDEFS).

I set DEBUG% TRUE and the debug.txt is as attached.

Thanks for confirming.

dpsharp wrote: Mon Oct 10, 2022 I've tried mounting the partition (named HardDisk2) with FAT32FS with
*FAT32FS:Mount HardDisk2
*Filer_OpenDir FAT32FS::HardDisk2.$

The README that comes with FAT32FS covers mounting partitions, but to mount the 3rd partition (the p3) on SDFS:0 (the :16) you'd need:

Code: Select all

fat32fs:mount -sfp3 :16

Has it locked, or have you hit the LOCAL ERROR stack corruption I reported back in 2021? I've added additional LOCAL ERROR's and re-uploaded 0.85 if you'd like to try again and see if it does generate a fatal error.

How many physical drives do you have on the ICS? And what version of IDEFS does the Podule have on it?
As its the IDENTIFY against IDEFS:1 that's hung, see what the following does from BASIC:

Code: Select all

SYS "OS_SWINumberFromString",,"IDEFS_DiscOp" TO A%
SYS A%+63,,3,0,&10000,0,&9000,1
*MEMORY B 10000+200

I mean LOCKED - the pointer no longer even moves. The machine needs a hard-reset to recover. Very serious.

JonAbbott wrote: Mon Oct 10, 2022 How many physical drives do you have on the ICS? And what version of IDEFS does the Podule have on it?

One physical drive - a 4GB CF card with four 495MB partitions.
It's not a podule, it's Wizzo - an extension ROM in the A5000 using the onboard IDE interface.
It's Wizzo 3.15 which is AFAIK the latest.

I'm not sure I can actually distinguish between Wizzo and ICS but as they're essentially identical, it just means it will show up as ICS in the debug logs and interface.

It sounds like Wizzo might have a bug - its possibly sitting in a timeout loop waiting for a non-existent drive to respond. I'll have to disassemble it to see what its actually doing.

What does the SYS sequence in my previous post do from BASIC?

That works beautifully, thanks Jon! Was able to happily create and reformat the FAT partition on the RPi SD card, mount it & use it immediately on my Mac and then back into the Pi.

Locks the machine hard here. But I'm not quite sure what the +63 business is supposed to be doing anyway - that looks wild to me.

It's the internal SWI to perform an IDE IDENTIFY.

Sounds like Wizzo might have a bug as that SWI should either timeout, or immediately return with an error if used against a non-existant drive. I'll need to reverse engineer the Module and see if I can either implement a software workaround or worst case, patch the Module.

Not sure if it's intended to cover this scope yet but accessing a Compact Flash card via a USB card reader on my Raspberrry Pi, that has an existing single Filecore partition I created with HForm on Risc PC running RISC OS 3.7, shows up as partition format <unknown> on v0.85.

The Pi seems to be able to access the partition fine. I'd not expected CF cards to mount as a SCSI:: drive so perhaps that's confused some logic somewhere.

It should read it as SCSIFS support is complete, please post a debug log created with 0.86.
