On ESP32, we rely on the IDF toolchain. This is a big part of the motivation for the recent move to fully use the IDF cmake-based build system (which was merged earlier this week). This has already made it possible to support the S2, and the plan is that the C3 should be similar.rdbrown0au wrote: ↑Fri Feb 19, 2021 5:59 amThe recent release of the Espressif ESP32-C3 will raise interest in this.
(So... good news for C3, but I don't think it helps much with other risc v ports).
