OM Systems OM-1 Mark II - not able to download

[coldfire22x]

I'm able to capture and save to the SD card but not download the captured images.

I've built libgphoto2 from 5f9f6c8 and gphoto2 from v2.5.8. Not 100% sure if #967 should be enough for download to work? No issues with my E-M1 Mark III's and I don't have an OM-1 Mark I to test with.

I think I missed this yesterday because I always started my tests with some sort of gphoto2 command unrelated to capture (auto-detect, summary, etc.). It seems that capture and download DOES work, but only on the first attempt.

Toward the end of the first capture and download there is an error:

ptp_usb_getresp [usb.c:516] (0): PTP_OC 0x1016 receiving resp failed: PTP General Error (0x2002)

Then near the beginning of subsequent attempts, a different error:

ptp_usb_getresp [usb.c:516] (0): PTP_OC 0x1016 receiving resp failed: PTP Device Busy (0x2019)

Logs generated from the following commands are attached.

one thing would be to try to comment out this line: (line 3267 in library.c)

                    CR (ptp_setdevicepropvalue (params, 0xD052, &propval, PTP_DTC_UINT16));

and see if that helps.

Also is this a dual image capture (raw+jpg)? if yes, try single-jpg or single-raw first if that works better?

It was set to single-raw .. I'll play with that setting on the camera with and without that line you mentioned, thanks!

@msmeissn Preliminary testing looks good on x86_64. The first two logs are with 0697bb0 (not working) and the last two are with the line you mentioned commented out.

1-capture-image.log 2-capture-image.log 3-commented-out-capture-image.log 4-commented-out-capture-image.log

Flipped the camera to RAW and plugged into an Orange Pi 5B. Looks like commenting out that line also works on aarch64:

arm64-commented-out-capture-image-raw1.log arm64-commented-out-capture-image-raw2.log arm64-commented-out-capture-image-raw3.log
