Have you been able to get this to fall apart in IDA?

What is the problem?
M32R processor, use or create Renesas M32172 register file definition and memory allocation.

Ah, problem was that I was using the wrong config file.
I'll have to make and try a M32172 cfg.
Thanks!

Have you been able to find the entry point for this ROM? I'm still getting strange results.

Analyze M32R documentation.
M32R executes the code from 0x00000 after reset.
There is a branch to 0xC00 primary bootloader.
TCM control code starts from 0x8084.
