- i.MX8M Plus EVK、カーネル 6.12.49-lts-next-g42fbadd4b2e9-dirty
- WiFi/BTモジュール:AW-XM729、ドライバbtnxpuart
- 同じハードウェア/カーネルで、Yoctoイメージが2つ:imx-image-core(BTは動作)vs imx-image-multimedia(BTが失敗)
問題
- マルチメディアイメージでは、 imx-sdma@30bd0000 がファームウェア準備完了を報告するのに約60秒かかります: [ 3.11] imx-sdma 30bd0000.dma-controller: sdmaまたはSDMAファームウェアが準備できていません!
[ 60.40 ] IMX-SDMA 30bd0000.dma-controller: ファームウェアを発見。 - BTNXPUARTは、SDMAが準備される前の~3〜7秒でBT UARTをプローブするため、UARTはDMAチャネルを取得できず、BTのタイムアウトHCI_Resetします。
imx-uart 30860000.serial: RX/TXのスレーブDMAに備えられません!
Bluetooth: hci0: Opcode 0x0c03 failed : -110 - 動作中のコアイメージでは、BTプローブの前に約3.7秒でSDMAの準備が整います。問題はありません。
