  • A few minor fixes and tweeks.
    Note: All object files updated and may be incompatible with previous releases

    V2.40 update in the top/first post.

    Minor fixes...
    OS240 v240 updated
    SD_DRIV v272 updated
    _PINDEF added

    Commands added...
    RSECTOR < sector_number_in_hex >
    DIRCPM < cpm_diskname > [ < cpm_filename > ]

    Entering any command without parameters will display the command syntax unless the command operates alone (ie DIR) where the command followed by ? (eg DIR ?) will display the syntax.

  • Hi Cluso,
    this sounds nice.
    Some years ago I earned some money programming a LSI11 running RT11XM. Later 68k with OS9.
    I am thinking, if I should build a P2 computer to control experiments.
    It should be able to run for xx days running at least one foreground job to control the experiment.
    I would like to log in and be able to start different background programs for example viewing the data while the experiment is still working.
    Can your system load resident programs into P2 cogs as such foreground jobs?
    Regards Christof

    Not yet although that is the intention. It’s not that difficult.

    Currently you could recompile with the extra code.

    I’ve been busy lately and now just getting enough free time to find the FAT32 bugs that have prevented me making progress on this. I just need to get load and run working next. Also, I need to make part of the OS stay resident and be able to load new commands. My P1 OS had separate loadable commands (eg DIR etc) so you just needed to make a new command and add that binary to the SD, without any changes to the existing OS. Currently they are all part of the one big binary requiring recompile when adding a new command to the source.

    A new update in the first post v2.41

    DIFF improved

    A new update in the first post v2.42

    _hubdef2.spin Reorganised and added some more fields. Now located in hub just below $7C000

    Improved information messages and general code tidy

  • Sounds super, can't wait to try it out.
    I just need to get an adapter I can plug into the pc then copy your OS to the SD Card.

    Hey @Cluso99, I noticed a bug in your SD_Driv

    The first thing startSD does is call stopSD() and in stopSD it fills2 bytes with -1 at ptr_mailbox, but it's not been initialised yet.

    you might want to put the
    ptr_mailbox := sd_mailbox
    before
    stopSD() ' stop cog if running

    PUB startSD(sd_mailbox) : result ' start SD Driver - uses a cog
    stopSD() ' stop cog if running
    ptr_mailbox := sd_mailbox
    sdcog := coginit(COGEXEC_NEW, @sddriver, ptr_mailbox) + 1 ' start sd driver cog
    return sdcog

    PUB stopSD() ' Stop SD Driver - frees a cog if driver was running
    if (sdcog) ' cog active?
    cogstop(sdcog-1) ' yes, shut it down
    sdcog := 0 ' and mark stopped
    bytefill(ptr_mailbox, -1, 2) ' reset object globals cmd=status=$FF

    Great work though as always bud :D

  • Cluso99Cluso99 Posts: 17,970

    Thanks for finding this baggers. Could be a nasty bug to find.

    There is actually no need for the stopSD in my OS as stopSD will not be present in the OS once it starts as soon as I get the commands back into separate binaries.

    I'm planning to put the sd_mailbox into fixed top hub with _HUBREF2 next.

  • BaggersBaggers Posts: 3,013

    No worries, saw it and thought I best mention it, in case it bites you at a later date. :)
