Comments in the makefile.inc suggest this port had little free memory, so it would be a good idea to check the CHDK memory info (or =return get_meminfo() in chdkptp) with Philmoz' build.

Having connected to all 16 cameras I used:

Code: [Select]

!savecon=con for lcon in mc:icams() do con=lcon cli:print_status(cli:execute('mup C:/CHDKPTP/PHILMOZ-DEBUG A/')) end con=savecon

to update to Phil's build. Apart from starting the uploads very quickly then slowing to a crawl for one or two cameras - no issues.

Then, using the chdkptp gui with a single camera:

Code: [Select]

> =return get_meminfo()
2:return:table:{chdk_start=63589344,free_size=204824,chdk_size=134224,allocated_size=1473528,free_block_count=12,name="combined",allocated_count=1582,chdk_malloc=true,free_block_max_size=202584,allocated_peak=1543784,total_size=1678408,}

Minor (?) teething problem - having then restarted multicam, what I think is the Alt helpscreen is (randomly) causing multicam to report script as not running on those cameras on which it is displayed. Two screenshots and a clitrace hopefully describe that.

Is there some lua code I could use in multicam to turn that off (it's a relatively major exercise to do anything individually on all the cameras) and do any balance in the GUI:

Code: [Select]

Edit:
in case it could be useful, I have an A2500 (described as beaten but 100% functional) arriving soon if that could help in testing anywhere.

Edit2: so, I set the Alt helpscreen to off in one camera then copied (via multicam) the cfg files from it to the other 15. That got rid of the Alt helpscreen appearance but not the "no script running" message (on 2 cameras) which I had assumed was connected to the occurrence of the Alt helpscreen. Will provide further update asap.

This feedback is, I think, quite strange so not sue what (if any) comment to expect. This is the first experience of anything like this.

Description:

I added this to multicam:

Code: [Select]

function mc:camstatus()
local cn=0
local nc=0
    for lcon in mc:icams() do
        if not lcon:is_connected() then
            nc=nc+1
            printf('#%s NOT connected\n',lcon.mc_id)
        else
            cn=cn+1
            printf('#%s connected\n',lcon.mc_id)
        end
    end
    printf('\nSummary: %d cameras (%d connected, %d disconnected)\n',cn+nc,cn,nc)
end

After successfully connecting to all cameras I confirmed connection via camstatus() . I then (attempted) to start the remote script's and display camera ID on each camera LCD. After this the cli reported that command having failed on Cam5&10 as no script was running. Executing camstatus() again revealed all 16 cameras as still connected (& unsurprisingly, there had been no usb disconnect sound throughout the test).

Screenshot of cam10 at test end attached.

This behaviour seems (to me) to have no natural link to any previously described issues but I can't currently imagine what this problem could be as a result of (other than the script not getting copied over and starting to execute, of course!).

200k is marginal, but may be sufficient to test.

Had the camera been switched to rec at this point? The camera will use some additional memory the first time it switches to rec.

You could keep lua memory usage at a minimum by putting
collectgarbage('collect') in the main loop of the camera side script, right before

local msg=read_usb_msg(mc.msg_timeout)

Yeah, the help screen shouldn't have anything to do with the script not running message. It's possible you might see something in the CHDK console (using "show last console" in the menu) of the cameras where the script isn't running.
Low memory could cause the script to exit.

No (oh dear).

Not exactly sure when i'll get the next bash at this but will try that and get back.

Thanks for suggestion and comment.

Edit1:
Of some interest, on a second test, scrpt initially failed to start on 2 cameras (oddly perhaps, these 2 cameras (Cam4&5) were two of the four which failed to start in the first test?) but another attempt to start script on all cameras (which includes clobbering those already running) was successful:

Edit2:
subsequently, with all scripts running:

lock ptp comms "on" was successful on all cameras
switch to record caused Cam 12 to crash (usb disconnect sound) - no romlog.

check free memory after switching to rec.
check for messages in the CHDK console on the cameras that fail with "script not running"

To test memory, I added the following to cameraside multicam:

Code: [Select]

function cmds.memory_stats()
    --e.g. to run !return mc:cmdwait('memory_stats')
    local memory_amount ={}
    memory_amount = get_meminfo()
    write_status(serialize(memory_amount), 'memory_details')
end

After connecting to all 16 cameras and attempting to start the remote script's, Cam5 reported as not running. Apart from lack of ID the camera display was the same as all other cameras (OK 0x3cc5830 / DEFAULT SCRIPT <ALT>)

Attempting to start the script's for a second time was successful on all cameras and the ID displayed on all. Function memory_stats followed by lock_ptp_comms executed on all cameras without fail but then switch to record caused Cam 12 to crash (usb disconnect sound) without romlog.

Having turned off all cameras and then connecting to Cam12 with the GUI provided pre & post record memory as:

Code: [Select]

> =return get_meminfo()
2:return:table:{chdk_start=63589344,free_size=204152,chdk_size=134224,allocated_size=1474200,free_block_count=11,name="combined",allocated_count=1584,chdk_malloc=true,free_block_max_size=202280,allocated_peak=1544416,total_size=1678408,}
> =return get_meminfo()
4:return:table:{chdk_start=63589344,free_size=203536,chdk_size=134224,allocated_size=1474832,free_block_count=7,name="combined",allocated_count=1607,chdk_malloc=true,free_block_max_size=203272,allocated_peak=1544416,total_size=1678408,}

Ths cli trace is attached.

Did you check "Miscellaneous -> Console -> Display last console" on the failed camera?

From your cli output, most cameras show free_block_max_size as only ~30kb, which is not nearly enough for stable operation.

Code: [Select]

 [5]={
  failed=false,
  done=true,
  status={
   msg="memory_details",
   cmd="memory_stats",
   status="{chdk_start=63589344,free_size=87840,chdk_size=134224,allocated_size=
1590264,free_block_count=181,name=\"combined\",allocated_count=2427,chdk_malloc=
true,free_block_max_size=30984,allocated_peak=1671536,total_size=1678408,}",
  },
 },

Interestingly, camera 14 shows free_size=459712 and free_block_max_size=218592. I wonder if that camera is still running the old build?
