So I started to play around with devicetrees, to build a minimal proof of concept. I looked into https://github.com/dgibson/dtc again and now I realized that libfdt does not offer an API for parsing a DTS (source) but an already compiled DTB (binary). The DTS handling is only done as an intermediate step. I now understand what @xiaoxiang781216 meant before regarding the DTS only existing during compilation. Zephyr directly parses and works using the DTS file using a python library (dtlib.py). I think that using dtc to build the DTS into a DTB first and then traverse that using libfdt (in order to generate whatever NuttX needs) is reasonable. So, I'm looking into writing a small tool that would parse DTB files using libfdt and generate a set of macro definitions to be included from NuttX. Would a tool like this written in C++ be acceptable to include in NuttX? Or is using C a requirement? Using the standard library could make it much easier to implement. I could force the use of a given C++ standard version if needed. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
