#
#       In plain English, IDA will look for the PLUGIN_ENTRY function which
#       should return a plugin object. This object can contain all the 
#       functionality itself, or it can have multiple actions.

You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

Description

The CTREE is built from the optimized microcode (maturity at CMAT_FINAL), it represents an AST-like tree with C statements and expressions. It can be printed as C code.
