Current status Edit

Added by Autopilot

Support for the Canon EOS 7D is almost frozen, having a running version of Magic Lantern might never happen.

Thanks to an anonymous donor we have a test 7D body and can produce a firmware dump from it.

The problem is handling the 2 instances of DryOS, one for each Digic. Currently we can generate signed firmware images and we have dumped the 7D's ROM for analysis, but we do not know how to hijack task execution on the Master/Slave (2 headed) DryOS instances. We are only able to produce a dumper and some debug functions. See See 7D_internals, 7d_intercom

• Apply this bspatch to the 7D 1.1.0 firmware (instructions and details) to generate a dumper firmware with md5sum f9d720f38c7991f9526d4b34e21c7d7c. Follow the normal "Update Firmware" procedure to write out a ROM0.bin file with the memory starting at 0xFF00_0000. The entry point is at 0xFF01_0000.

• See 7d 1.2.3 dumper
• we can produce a dumper for 1.2.5 if needed.
