It's not really a problem now because we only have a host package so we only define HOST_TI_CGT_PRU_DIR, but still, it's inconsistent. So the variable name should be e.g. TI_CGT_PRU_INSTALLDIR. Also, I don't think it's necessary to put the version in the installation directory name. We're not going to support side-by-side install of different versions. But that's just a minor nit.

Good question: only because I didn't know it had been released and hadn't tested with it :). Okay if I keep with 2.1.3 for the moment? The rest of the feedback makes good sense---thanks! --Ash

TI provides a binary code generation toolchain to develop firmware for the programmable real-time unit/co-processor found in some SOCs such as some models in the AM335x line. This toolchain includes C/C++ support (clpru) rather than just assembler (pasm) supported by the pre-existing am335x-pru-package [1]. Following the lead of the Yocto meta-ti layer [2], this package provides a host toolchain suitable for an x86 (or x86_64) Linux targeting an ARM-based PRU core.
