Thanks again for this really great project and I'm looking forward to using and adding to it. Pardon my getting started with OVMS & esp-idf, I suspect I have an issue with my setup in terms of the path being correctly defined? I attempted to follow the google docs OVMS developer guide, but I must be missing something. The developer guide and the esp-idf instructions seem clear until the esp-idf instructions to run the install.sh script (setting paths, etc), but this script or similar doesn't exist in the openvehicles esp-idf branch? And the openvehicles esp-idf is a few months old, many items from the master esp-idf are different now? does that matter? Do the instructions mean to install and set up the espressif's master esp-idf, and then also clone the openvehicles esp-idf? Because I think that's what I've done. I installed the dependencies and espressif's esp-idf, and am able to flash at least hello_world on a regular esp32 board over USB and the serial terminal works with it. So that seems good. When I try to compile OVMS I get errors that look like I'm missing something. Maybe the something I'm missing is in the openvehicles esp-idf, but my paths are not including it? Is there a script in the openvehicles esp-idf that I need to run? Is it ok to have both versions of esp-idf set up at the same time? First it gives errors about the copyright text to include in the binary? dklein@___:~/Leaf/OVMS/v3/vehicle/OVMS.V3$ make Toolchain path: /home/dklein/.espressif/tools/xtensa-esp32-elf/esp-2019r2-8.2.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gcc Toolchain version: esp-2019r2 Compiler version: 8.2.0 Python requirements from /home/dklein/esp/esp-idf/requirements.txt are satisfied.
