Xiao nRF54L15でRISC-VとIPC通信できなかった件

個人的な上手くできなかった忘備録メモです。

Xiao nRF54L15でRISC-VとIPC通信できなかった件を雑にメモ残しています。

nRF54L15-DKではOK

Nordicの評価ボードであるnRF54L15DKでは問題なく動作します。

Xiao nRF54L15ではNG

最初にXiao nRF54L!5のdtsにはRISC-VにUARTが無いので、prj,confを弄る必要があった。

エラーが出たため、変にLOGメッセージが表示させないようにした。

CONFIG_PRINTK=n

CONFIG_LOG=n

CONFIG_PRINTK=n

CONFIG_IPC_SERVICE=y
CONFIG_IPC_SERVICE_BACKEND_ICMSG=y
CONFIG_MBOX=y

最初のIPCのハンドシェイクは上手くいっている様子だが、その後が？状態。

M33コアのログは下記のように止まってしまう

止まっている箇所を弄ってみたが上手く動かず。

nrf54L15-DKとのdtsの差分を見たが、XIAOの方はRISC-Vのメモリを違った切り方をしている。

これが原因なのか追ってみたがちょっと分からず
