Script for getting a list of some known memory ranges, discussed in this thread and elsewhere. Sadly, this eventproc is no longer available on R6 (and probably R5), memory handling seems to have been reworked on those new models.

Code: [Select]

private sub Initialize()

dumpf()

For example, sx740 outputs this (text needs cleaning as unprintable characters are in it and newlines are missing sometimes):

Hey Srsa that script worked on the R6.

It's a logfile of 170KB. Is this log file publically shareable?

Hey Srsa that script worked on the R6.

I used ExecuteEventProcedure to avoid crashing cameras that don't have smemShowFix. As I mentioned, the R6 is missing that event procedure. Your log is therefore only a regular log without memory range info.

It's a logfile of 170KB. Is this log file publically shareable?

These logs are regularly shared in this forum, so I guess yes. But in this case, it would be pointless.
The R6 1.0.1 firmware has a list of memory range names (list of pointers is located at 0x7A3C in RAM, the firmware has references to 0x7A2C in case you have a disassembly to look at). But, I could not find an equivalent of smemShowFix from a quick look.

[a1ex]

SX740 picture posted over here.

The R5/R6 don't have smemShowFix, but they seem to have some similar strings, like USER_BMPVRAM, USER_IMGVRAM_1, USER_MOVIE_REC_WORK_2, USER_DAF_RAW and many others:

Code: [Select]

strings gang100.bin |grep '^USER_'

The routine referencing these strings is likely the equivalent of smemShowFix.

Now if someone could figure out if it is possible to disable focus box on M50 to get clean HDMI.
That was done on M100:

Would it be possible to switch off the automatic crop mode with Canon Basic if Caonon EFS lenses are connected?

[yourboylloyd]

Probably if we knew all of the right stubs and what to enable/disable. Canon basic seems powerful. I'm still learning but don't count on it because I'm noob.

[coon]

You can write to any memory location by using Poke32 / Poke16 / Poke8, so in theorey it is possible to modify canon code in RAM like that. We only need to find the code locations.
Are you able to revert autocrop when EF-S lens is mounted or is that option locked then?

[c_joerg]

I don't have an R yet myself, but the menu is locked with EF-S lenses. This is not a problem with Sigma lenses. The EF-S 55-250 works really well with the 6d with intermediate rings.

I wonder about the increase in TotalShoot and TotalShutter counters.

I have an EOS R that I bought used a year ago.
The seller told me that he took approx 1800 images and I have taken approx 1500 pictures and 300 videos.

Those counters now look like this:
<TotalShoot> 33991 </TotalShoot>
<TotalShutter> 3275 </TotalShutter>

I don’t think the previous owner would have taken over 30000 photos in such a short time.

[c_joerg]

So far confirmed to exist on:
PowerShot SX740
EOS M50
EOS R, RP, R5, R6
EOS 250D

Works as well on EOS M6 Mk2, G5X Mark II and  90D.

[T7i owner]

What about the T8i?

[Walter Schulz]

Should work but nobody tried and reported back. So: No confirmation.
