VT Supercharged $A5 DARC Dissassembly (can reassemble)

Postby antus » Sat Aug 29, 2009 3:07 pm

Like the VS DSTK project this can re-assemble the original bin using the GNU tools on a linux environment. If browsing the contents of the archive on windows use wordpad which can handle linux text files fine. It seems these methods are working fine for newer bins :thumbup:

update: memory.x page0 should be start 0x0000 length=0x400 (which will provide a ram range 0x0000->0x03FF). Length in version 1 package length=0x3FF is off by one (provides 0->3FE)

I've been having a bit of a look through this disassembly, and I have noticed that it reads and writes to memory in the 0x1800 - 0x1Cxx range.
Is there another memory device on the bus (since writing to the memcal is pointless being an eprom) ?

I think thats the I/O addresses for control of the ports/pins.

this is in reference to one of the Holden calibration engineers that passed away during the development phase of VT S/C
