IDA Pro - how to correctly load a non-PC binary (presumably mpc860)?

Question

reverse engineering

The binary is not encrypted - the content contains the lines "/dev/tty", "DMALLOC_CHECK", a couple of IP addresses, etc.
When loaded into IDA Pro, these lines are not referenced, some are even recognized incorrectly.
I suspect that Ida needs help by specifying the RAM and ROM segments (starting address, loading address). Is there a method for searching (selecting) these addresses?
How can I try to download the binary again?

Answer 1

Is there any other information about the file? Where is it drained from, what should it be poured somewhere? What does the file command say about it?

Answer 2

file, binwalk don't recognize anything. The filler opened it - he stupidly beats this file into pieces and sends it to the device. Without processing and additional data.
There is practically no data on the device itself either, presumably PowerPC MPC860.
I understand that it turns out to be a task for a psychic - to unravel something, I don’t know what.
I see the only option - brute force some thread of parameters when loading. I already tried to brute load address using console commands - the result is also zero so far.
