From c0b64a3f23639bcc52d1488728771560bc9a1d0a Mon Sep 17 00:00:00 2001 From: Jim Mussared Date: Wed, 16 Aug 2023 16:45:09 +1000 Subject: [PATCH] mimxrt/boards/make-pins.py: Update to use tools/boardgen.py. Minor change to remove support for using numeric IDs for machine.Pin. This was previously based on the index of the pin in the board csv, but this is different (and incompatible) with other ports. This work was funded through GitHub Sponsors.
