GIC-500 ICのITSのアドレスを理解するのに苦労しています。
imx8qmのリファレンスマニュアルには、GICが0x51a00000にマッピングされているという情報があります。次に、GIC-500のメモリマッピングを確認すると、ITSメモリマップアドレスが0x51a20000と仮定します。しかし、ITS から一部のレジスタにアクセスしようとすると、実行が停止します。
いくつかのデバイスツリーを確認したところ、一部の領域は0x52000000アドレスの割り込みコントローラノードにマップされています。もしかしたらこれがITSでしょうか?リファレンス マニュアルには、このアドレスに関する情報はありません。
正しいITSベースアドレスを理解するのを手伝ってもらえますか?
