Hi all, this is probably a long shot from far out of left field, but I wonder if anyone is familiar with the deep inner workings of the 1600R series routers?
Long story short, I got a bit bored recently with all of the coronavirus related restrictions, and started to reverse engineer some older model Cisco routers (2500 and 1600R) that are based on Motorola 68000 family CPUs, with a "no particular reason" goal of making FreeRTOS run on them (achievement unlocked.) But the 1600R is throwing me a curve ball, and Im having difficulty seemingly "unlocking" access to the memory ranges that cover the WIC slot and the PCMCIA controller registers. Ive used Ghidra to disassemble and rummage through the factory boot ROM code to figure out basically "what Cisco did", and re-implemented it myself, but I still seem to be missing something. Basically, I wondered if someone here might be familiar enough with these old boxes at a low enough level and might know if there is something in particular that needs to be poked to make this work? Thanks in advance!
