Well after saying I wouldn't finish it. I finished the jig for the 805. I successfully updated my 805 from 1.04 (with updater 1.00) to 1.08 with updater 1.01 now. I will post all the details within a couple days, including PCB layout, for those few who would want to try this. Performing the update seems very doable for the novice, if a jig is available, but making a jig should only be attempted with experience
And yes a jig is required to update, as my prior thought (posting) about not needing it was wishful thinking.
Now my question is how does one update the HDMI firmware? Yes, there is another jack there, but seems like the marking on the board are different, which would indicate a different jig. But it might be the case that the main chip has an embedded Renesas MCU???? The available 1.08 firmware archive contains the code for both the DSP and HDMI updates in the .mot format. The configuration file lists the files that would seem to indicate that somehow the updater can update this firmware over the serial port. A user posted a while back that the HDMI code was the ONE firmware that could be updated with updater 1.00. So does anyone know how to do this?
Second, if firmware 1.10 is still "delayed", how about giving us the 1.09 firmware as this might be the last?
