2011 and later entry level cameras have a dummy version of DisableLensError, which has no effect. These cameras seem to be the ones without optical IS hardware (A800, A810, A1200, A1300, A2200, A2300
Which means you either need a hardware solution like spectroplasm posted, or additional reverse engineering.

Something on the computer 'talks' to the camera and sets it to a different internal state. This is known to cause problems. Try to disable the software component that causes it.

Just to close out this issue: after a fair amount of research (related: gvfs documentation is appalling) I found that making the following edit to /usr/share/dbus-1/services/org.gtk.Private.GPhoto2VolumeMonitor.service was the minimal edit required to get my camera happy:

Code: [Select]
[D-BUS Service]
Name=org.gtk.Private.GPhoto2VolumeMonitor
Exec=/bin/false
#Exec=/usr/lib/gvfs/gvfs-gphoto2-volume-monitor

I guess that the CHDK image doesn't like the PTP mount by libgphoto2 for some reason.

Thanks to everyone that helped.

Good to know.

FWIW,  it's the camera firmware's reaction to some normal (non CHDK) PTP commands, not really specific to CHDK.

An alternative way to deal with this is through udev rules:

This is useful in the case where you might want other devices to continue to work with libgphoto

Good point. I've now backed out my change to the dbus service definition and made the following edit to a copy of /lib/udev/rules.d/40-libgphoto2-6.rules that I've made in /etc/udev/rules.d/; what was /lib/udev/rules.d/40-libgphoto2-6.rules:

Code: [Select]
ACTION!="add", GOTO="libgphoto2_rules_end"
SUBSYSTEM!="usb", GOTO="libgphoto2_usb_end"
ENV{ID_USB_INTERFACES}=="", IMPORT{builtin}="usb_id"
ENV{ID_USB_INTERFACES}=="*:060101:*", ENV{ID_GPHOTO2}="1", ENV{GPHOTO2_DRIVER}="PTP", MODE="0664", GROUP="plugdev"

LABEL="libgphoto2_rules_end"

is now in /etc/udev/rules.d/40-libgphoto2-6.rules

Code: [Select]
ACTION!="add", GOTO="libgphoto2_rules_end"
SUBSYSTEM!="usb", GOTO="libgphoto2_usb_end"
ENV{ID_USB_INTERFACES}=="", IMPORT{builtin}="usb_id"
ENV{ID_USB_INTERFACES}=="*:060101:*", ATTR{idVendor}=="04a9", MODE="0664", GROUP="plugdev", GOTO="libgphoto2_rules_end"
ENV{ID_USB_INTERFACES}=="*:060101:*", ENV{ID_GPHOTO2}="1", ENV{GPHOTO2_DRIVER}="PTP", MODE="0664", GROUP="plugdev"

LABEL="libgphoto2_rules_end"
This inhibits libgphoto2 PTP mounter launching for all Canon cameras (and these Canons for CHDKPTP use are the only Canons I own).

Ultimate 4.1 was running fine on an A470. Now when I run it on an A2200, I get a " :1: not enough memory error". Could this be a firmware issue?
What canon firmware version does your camera have?

Can you report what get from "show memory info" in the CHDK misc menu?

There is an oddity in this port that versions 100b and 100c are not configured to use EXMEM, but 100d is. This should not vary by sub, if one doesn't have enough memory, then the others almost certainly don't either.

Yup, that's really not enough.

Here's a build with ARAM enabled. Please report whether this fixes your problem, and how much free memory is available.

edit:
bad build removed, see below

First I replaced the old CHDK software with the new. Camera would not even power on until I inserted a non-CHDK card that was locked. Also had to remove and replace battery.


So, I low level formatted the card and copied over the new software, locked the card. Powered on, did not boot, got "memory card locked" message.


Hmmm. I've not been using this long enough to know that is going on,

You're sure your camera is an A2200 with Canon firmware 100b? If so, I probably messed something up, but I don't see what. edit; see next post.

Do you know what CHDK version you had installed before?

Formatting the card erases the Canon boot flag, so you will need to make the card bootable again to autoboot. You can try loading with the "firmware update" option. If it works, you can make the card bootable in the CHDK miscellaneous -> SD card menu. I suspect that the build I posted will crash the same as autoboot did though.

You can also use stick http://zenoshrdlu.com/stick/stick.html to re-install and make the card bootable.

Found my mistake (forgot to set MEMISOSTART  :-[ ), new test build attached.
