The 1200D is in the progress of porting. When a crash occurs (ERR 70) it is always this error:
ASSERT: FALSE at ASIF\ASIF.c:486, task ASIF lv:0 mode:3 Magic Lantern version : Nightly.2016Jul24.1200D101 Mercurial changeset : d0ffefa7d840+ (1200D) tip Built on 2016-07-24 10:15:12 UTC by mathew@mathew-VirtualBox-15. Free Memory : 247K + 1274K
The crash (mostly) happens in the following situations: - After you ran the stubs api test from selftest.mo and it finished - When running the random tests from selftest.mo after some time - When: 1) Set the "quality warning" in Prefs -> Warning for bad settings 2) Continue to use the menu
All these crashes create the same error as above (ASIF).
