Hi Alexey, Thanks for the update. A couple of questions. Do you intend on adding the copyright headers or a blanket license to: https://github.com/espressif/newlib-esp32 which appears to be where these files were previous to being proposed for newlib? There is one file that doesn't appear on your github site: sim-vectors.S. It has a different license/copyright owner from the rest of the files and I was wondering if you could provide any detail of where it came from? -- Jeff J.
