LCD_CAM interrupt allocation of camera failed

[eclps123]

同时使用i80bus和摄像头模块，会出现 LCD_CAM interrupt allocation of camera failed。可能是中断配置方面的问题，但我不知道如何解决它

同问, 我也遇到了同样的问题. esp-idf版本5.1.2. ESP32S3 LCD用i80接口或者RGB接口, 同时使用Camera, 就会出现这种情况. 如果先初始化LCD, 则Camera初始化失败, 如果先初始化Camera, 则LCD初始化失败. 如果LCD用SPI接口, 则没有问题. 定位到 esp_intr_alloc_intrstatus -> get_available_int 这里, 中断配置失败. LCD和Camera的中断配置出现冲突, 不知道怎么解决.

LCD和Camera初始化冲突找到解决办法, 确实是配置中断的冲突, LCD和Camera中断用同一个中断源, 导致分配中断失败. 解决办法是LCD中断和Camera中断分配到不同的CPU. 比如LCD在CPU0 任务里初始化, Camera在CPU1任务里初始化. 另外发现必须先初始化Camera再初始化LCD, 否则还是有异常, 这个没发现什么原因.
