→Binwalk / Binvis -
This device has two firmware version strings visible in the firmware (at this point the strings are the only thing I've been able to see)
Appears it was already updated in the field to the last OS version (1.022) from I'm not sure if it then wipes the other bank? Possibly, because the other regions are written with FF. However it was still pretty confusing to navigate around later on; BRA from active code to 0xFF region. Probably these are the as yet un-mapped SRAM, and Alesis IC addresses. I've added peripheral mapping for the SCI. I'm still not sure: learning a lot as I go! Also maybe the Alesis ASIC remaps certain memory addresses at run time? (more research has shown that this is very likely) I've added peripheral mapping for the SCI, still it's tricky to find things with little experience. I am learning a lot though.
