    I'm pretty sure the card I used with this is OK...

    Pretty sure? Be certain and check it on your P2 board like I said, it'll only take less than a minute to do so.

    I just remembered @Cluso99 saying something about not supporting non-SDHC cards. Tried with SDHC card and get something that looks better:
    *Auto Detected P2EVAL
    
    Cluso's P2 Z80 Emulation: Experimental v053a
    
    SD Driver cog= 1
    
    Initialise
    
    Find Directory
    
    Find file(s)
    
      A: ZICOG_A2.DSK *** SD error *** F

    Yes, my later code (the ROM is fine) only supports the SDHC in sector address mode. Old SD and SDHC cards in byte mode will be rejected.

    What about SDXC? Do these all support sector mode?
    (wondering whether this may explain anything since most of my testing has been with SDXC cards)
  • I'm always surprised when someone is found to be using old old old or any old SD cards.

    @Cluso99 - Isn't it only SD cards that use byte addressing? From SDHC on they used block addressing.

    No. SDHC cards originally were byte addressing. It was the v2 spec. I identified SDHC sector mode as v3 but it is IIRC v2.1.
    Anyway, I removed support for the older byte addressing cards from my P2 software drivers a few months ago.

    @Tubular,
    SDXC are backwards compatible with SDHC (sector addressing) although they are often/always originally formatted as exFAT and my drivers require FAT32. Note: P2 ROM can boot from exFAT cards, but can only load from the Boot or Vol sectors as it does not actually recognise exFAT (see the P2 ROM SD Boot writeup/thread).
  • Ok. I hope to get back to testing cards some time, but its not a priority. I would love to understand it all better
  • Don't forget that TAQOZ can format SDHC/SDXC cards in FAT32 with the required hidden partition and in whatever cluster size you spec, but normally 32kB/cluster.

    You think it would be difficult to emulate and Amstrad 8256 or 8512?

    I haven't updated this in a long time. I posted code to my RetroBlade2 thread a long time ago with the latest code but missed doing it here.
    There are some bugs and I've had to revert to this version each time because I haven't had sufficient time to find the problems in my later versions.

    So here is OS228c that goes back to 2020-11-28. It's a bit of a mess, but it will do DIR of the SD card.
    You will need to use FlexProp - I used v5.2.0 today

    This is also the basis of my Z80/CPM for P2 which also works. You can run MSBASIC :)

    There is more info here

    I've found the cause of the error(s) - now to find the fix ;)

    When I have two instances of FAT32, the second one locks when used. With a minor change I have DIR working now.

    So, when I converted FAT32 to use my SD_DRIV driver, rather than the ROM driver, I removed/adjusted the vars. I probably have something in a DAT that needs to be in a VAR, and now all I need to do is find it/them.

    If I get a chance today, I'll strip out the other code so that only one instance of FAT32 is used and I'll post this version. Otherwise it will likely be a week before I get another chance.
