From 776be79f7bb10b09e795e2ea93bb795a653c9b4c Mon Sep 17 00:00:00 2001 From: Ulf Lilleengen Date: Fri, 24 Jun 2022 19:56:15 +0200 Subject: Move bootloader main to examples This should remove some confusion around embassy-boot-* being a library vs. a binary. The binary is now an example bootloader instead. --- examples/boot/application/nrf/.cargo/config.toml | 9 +++++ examples/boot/application/nrf/Cargo.toml | 18 +++++++++
