GetCameraInformationData and AdjLog

There is a reference to "freefall" in the firmware, which would appear to be output by GetCameraInformationData and seems like it might record something about whether a camera was dropped. I thought it might be interesting to get this on a camera that had a hard fall but I haven't been able to figure where it goes. It seems like it could be related to "StartLogOut" "OutputLogToFile", AdjLog.txt etc. I was able to get content in AdjLog.txt using

Code: [Select]

=return call_event_proc('FA.Create')
=return call_event_proc('InitializeAdjustmentSystem')
=return call_event_proc('StartLogOut',2,0x1000,0)
=return call_event_proc('OutputLogToFile')

However, calling GetCameraInformationData and (and GetTotalShootCount, which appears to use similar functions) didn't result in any output.

StartLogOut appears to take 3 arguments: mode, buffer size, and optional filename. Mode appears to range from -3 to +3, with +/-2 being connected to the AjdLog.txt, and the others possibly not.

There are also functions ActivateAdjLog and InactivateAdjLog, which appear to check a field in the adjlog related struct that I don't see being set anywhere.

I've done something similar here in Reply #304
.https://chdk.setepontos.com/index.php?topic=12542.300
CameraInfo.xml says that FreeFall TotalCount = 0.

Not sure if it was powered off by the time it hit.

I was sure, my S110 was off when it hit…

Thanks! I remembered there was discussion but couldn't find it. I'll check in RAM.

I finally got around to looking at this for other reasons, so here's a way to get the GetCameraInformationData XML.

The first function called by GetCameraInformationData (g7x 100d 0xfc5087ae) collects the actual data and puts it in memory allocated with umalloc. It expects a single argument, which is a pointer that receives the allocated buffer (it also stores it in a global variable, but the pointer is required anyway) It returns the length of the data. So using g7x 100d as an example

Code: [Select]

 =call_event_proc'System.Create' p=call_event_proc('AllocateMemory',4) return call_func_ptr(0xfc5087af,p),p,peek(p)
1:return:2912
1:return:5475504
1:return:1079217376
rmem 1079217376 2912 -f=g7x-caminfo.xml

My g7x did not show anything in the FreeFall section of the log, and the TotalShoot value was obviously far less than the real value (~6k, when I know the counter has wrapped passed 9999 multiple times).
The ErrorLog section shows a history of hardware defect errors.
The BatteryAuthentication section shows a history of the last ten times a non-Canon battery power source was detected. In my case, all of these correctly showed "DC coupler".

There is also a section appears to show what power sources have been used in the camera lifetime

Code: [Select]

<Explanation>Whether any non-Canon battery was used</Explanation>
<ThirdParty>YES</ThirdParty>
<Counterfeit>NO</Counterfeit>
<DC-coupler>YES</DC-coupler>
<non-CANON>NO</non-CANON>

Interesting that "ThirdParty" "Counterfeit" and "non-Canon" are all separate categories. I previously experimented with blocking various terminals, which might explain the "ThirdParty" entry on mine.

On my sx410 the log looks pretty simplified.
TotalShoot value shows a slightly higher value, the difference is approximately 150 to the value shown on the camera display, but during development I somehow reset the time and number of images, maybe that can explain the difference.
The ErrorLog section did not show anything.

Code: [Select]

-<FirmwareVer>
<Internal>Firmware Ver GM1.00C</Internal>
<Major>1.0.0.0</Major>
</FirmwareVer>
<ErrorLog/>
<TotalShoot>3507</TotalShoot>
<ZoomRetryCount>0</ZoomRetryCount>
<PowerOnCount>1690</PowerOnCount>
<TotalRunningTime>327765</TotalRunningTime>
<ZoomMoveCount>3071</ZoomMoveCount>
</CameraInfo>
</Canon>

The ErrorLog section did not show anything.

All my cams show ErrorLog section

The following basic script does the same for all newer canon cams

I don’t seem to have caused any hardware errors in 5 years, even though the camera fell from 2 meters to the floor 7 months ago.
Now I forced an E18 error for the test.

In addition to the E18 error, the battery temperature value also appeared.
If anyone else wants to see GetCameraInformationData on sx410 fw100c, the pointer is 0xFFBD085C.

Code: [Select]

-<ErrorLog>
-<Log>
<DateTime>2021.07.19 14:22:40</DateTime>
<Reason>E18 ZoomLensSpeedError</Reason>
<BatteryTemperature>297 30</BatteryTemperature>
</ErrorLog>

Was the camera on or off when that happened?
I have never seen FreeFall > 0.

The turned off camera fell out from the closet in the M6.4 earthquake.
No damage is visible, only the slightly noisier zoom mechanism was the first few minutes of operation.

~~Some~~ 13

.../.../funcs_by_name.csv have a line like

0xe050178b,CamInfo_Debug_FW

probably Ix180 too ...

Code: [Select]

<?xml version="1.0"?><Canon><CameraInfo><Serial>313061007584</Serial><FirmwareVer><Internal>Firmware Ver GM1.00A</Internal><Major>1.0.0.0</Major></FirmwareVer><ErrorList></ErrorList><TotalShoot>381</TotalShoot><ZoomRetryCount>0</ZoomRetryCount><PowerOnCount>251</PowerOnCount><TotalRunningTime>24937</TotalRunningTime><ZoomMoveCount>261</ZoomMoveCount><TotalZoomMoveCount>265</TotalZoomMoveCount><ZoomResetCount>216</ZoomResetCount></CameraInfo></Canon>

Maybe on others (Ix265, M3) the canon basic script doesn´t work...?
