For some fun between debugging:  :)
Same CHDK as compiled for my 101b without ExMem trouble, 4h lowres video and ptp 240p life-view.
(needs? dial at <P>, not StdVideo)
Free mem after ptp connection -> rec -> play :
So, if I can translate, you are able to record low res video with PTP connected, when CHDK is built without exmem?
All my home builts are compiled without the EXMEM_MALLOC and CHDK_IN_EXMEM switches, no configs.inc... changed.
Free mem after booting to <play> is ~400k, to <rec> ~570k, firmware update same ~400k. :)
Code: [Select]
sx230hs, 101b  (FHD)

Oops, I misread your screenshot. 160K is CHDK size, free space (actually largest free block) is 275K, which might be OK, but is still quite low.

Yes, that makes sense. Can you check if MOVIE_REC is the same when you do not have USB connected?

Hi guys,

Posting here as it is related to video download and crash.

I resorted to my SX220HS to test the video script and got a crash when I requested a reboot. I have observed that it happens when I download a .mov file over ptp that was recorded earlier, delete all files over ptp (imrm), and then reboot the camera over ptp, the reboot fails. Attached is the ROMLOG. Note that the unsafe IO was turned off.

con 2> =return get_buildinfo()
3:return:table:{platform="sx220hs",build_date="Dec  6 2021",build_number="1.6.0",build_time="16:11:11",version="CHDK",platsub="101e",build_revision="6022",digic=40,platformid=12844,os="dryos"}

Let me know if I better create a new thread for this one. I did not yet test with CHDK 1.5 though.

Did you switch to play mode before deleting the file?

Some cameras crash with an assert similar to this on switching to play or shutting down after images are deleted in rec. I don't specifically recall anyone reporting it for video, but my impression is video is much less used with PTP, and is likely treated similarly to stills by the subsystem involved.

There should be no need to test 1.5, it's very unlikely to be CHDK version specific.

Thanks. That helps indeed.
