MA35D1 RTP GPIO_PowerDown喚醒問題

发表于 2024-5-31 15:04:17

運行RTP GPIO_PowerDown程序, 觸發I/O腳位後. 但M4端無喚醒, 反而A35內核崩潰出現下列訊息. 可能的問題為何?

请从这个地址更新内核、TFA、示例代码

內核已使用Github://OpenNuvoton/buildroot_2024更新. 問題同樣會發生...
TFA的device tree設定
gpio_s = <PM2_SUBM>,
<PK9_SUBM>,

測試後問題發生是在設定GPIO_EnableInt後, GPIO觸發狀態改變後, Linux內核過一陣子出現內核崩潰訊息.
RTP Code :
GPIO_SetMode(PM, BIT2, GPIO_MODE_INPUT);
GPIO_EnableInt(PM, 2, GPIO_INT_FALLING);
NVIC_EnableIRQ(GPM_IRQn);
