Hello to you all! In this blog, we will focus on low power management in PCIe. PCIe Power management aims at reducing power consumption in PCIe devices by putting them to low power states when they are idle and bringing them back to full power state when required.

Why does it matter ?  Because PCIe devices in the market such as graphic cards, storage devices, Network Interface Cards can consume significant power when they are active. Power management allows them to scale down their power consumption during idle or periods of low activity.

このシリーズでは、低コストでコンパクトな開発ボード「FRDM i.MX 93 Development Board」を用いて、i.MX 93内のCortex-M33コア向けのSDKサンプルコードのビルドと実行方法を、ハンズオン形式で全3回にわたって解説します。

• 【第1回】開発環境構築とMコアイメージのビルド
• 【第2回】U-BootとremoteprocによるMコア実行（本記事）
• 【第3回】ブートローダーによるMコアの自動起動
