XIAO nRF54L15でプログラム書き込めなくなった場合の対応
XIAO nRF54L15でプログラムを何回か書き込んでいると、途中でエラーが出ました。
下記のような赤字エラーです。
ATAL ERROR: command exited with status 1: C:/ProgramData/chocolatey/bin/openocd.exe -s 'C:/ncs/platform-seeedboards/zephyr/boards/arm/xiao_nrf54l15\support' -s 'C:\Program Files/OpenOCD/share/openocd/scripts' -f 'C:/ncs/platform-seeedboards/zephyr/boards/arm/xiao_nrf54l15\support\openocd.cfg' '-c init' '-c targets' -c 'reset init' -c 'nrf54l-load C:/boards/test/imu_dataforwarder/build/merged.hex' -c 'reset run' -c shutdown
それ以降書き込めなりましたが、Seeed公式からのリセット手順で直すことが出来ました。
Factory_Reset(ファクトリーリセット)を実施した旨を紹介します。
実際にリセットした際の動画が下記となります。

まとめ
XIAO nRF54L15でプログラムを何回か書き込んでいると、途中でエラーが出ました。
それ以降書き込めなりましたが、Seeed公式からのリセット手順で直すことが出来ました。
Factory_Resetを実施した旨を紹介しました。
