If someone could provide RAM dump(s), we could find out whether the
issue (missing bitmap buffer) philmoz encountered on the G5x is affecting this camera.
The following
Canon Basic script can be used to dump the whole camera RAM (512 MB). The card needs to be set up like
this.
' dump RAM to A/RAM.BIN
' log to A/CBDUMP.LOG
' a working script blocks the camera until finished
DIM startaddr=0
' following is the size of RAM to dump (has to be adjusted to not exceed the amount of camera RAM)
DIM dumpsize=0x20000000
DIM lcdmsg=0
DIM msgstr=0
DIM fname="A/RAM.BIN"
private sub RegisterProcs()
if System.Create() = -1 then
SystemEventInit()
end if
if ExecuteEventProcedure("UI_RegistDebugEventProc") = -1 then
ExecuteEventProcedure("UI.CreatePublic")
end if
end sub
private sub InitMsg()
lcdmsg = ExecuteEventProcedure("LCDMsg_Create",10,10,"Started",2)
if lcdmsg >= 0 then
LCDMsg_ChangeColor(lcdmsg,2)
end if
msgstr = AllocateMemory(80)
end sub
private sub PutMsg(msg)
if lcdmsg >= 0 then
LCDMsg_SetStr(lcdmsg,msg,0)
end if
msgfile = Fopen_Fut("A/CBDUMP.LOG","a")
if msgfile <> 0 then
Fwrite_Fut(msg,strlen(msg),1,msgfile)
Fwrite_Fut("\n",1,1,msgfile)
Fclose_Fut(msgfile)
end if
end sub
private sub Initialize()
RegisterProcs()
InitMsg()
PutMsg("Started")
sprintf(msgstr,"%0X",startaddr)
PutMsg(msgstr)
dumpfile = Fopen_Fut(fname,"w")
if dumpfile <> 0 then
Fwrite_Fut(startaddr,dumpsize,1,dumpfile)
Fclose_Fut(dumpfile)
Wait(500)
PutMsg("done")
else
PutMsg("file error")
end if
FreeMemory(msgstr)
end sub
You can make a dump in either playback or rec mode, but you need to name the script file accordingly.
A script named
extend.m can be started by pressing SET in playback mode. A script named
autotest.m can be started by holding SET and pressing RIGHT in rec (shooting) mode.
Before you make a dump, make sure there is a visible JPEG (or live view when in rec mode) displayed on the LCD. Also make sure that there is some visible Canon overlay (exposure info, icons and such).
Note that the dump may include file(s) from the card and whatever is displayed on the LCD, so remove anything from there that you don't want to publish.
Compress the dump before sharing it.
