相机接入描述:
11V 两个8M x8b raw12 两个8M x3c raw12,7个YUV422相机1920x1280,11V都是30fps
现在是MIPI0 MIPI1 分别接入一个x8b+x3c,isp0 处理x8b做直通,剩下的一个x8b和两个x3c使用isp1处理,7个x3j分别接在MIPI2上三个,MIPI3上三个
单独每个MIPI分别打开都很正常,或者同时开两个MIPI也很正常,如果MIPI0 MIPI1和MIPI3同时开,内核就会频繁打印[fchm_ncf_irq_handler, 102]NON-Critical error happened, module_name:tee_cam_noc, ncf = 250! 和[A][time_1 :1700619938 s, 327058 us], ncf = 250!这两种打印,频率很高
想问一下这个相机接入架构下,这是内存带宽达到瓶颈了吗,有没有什么排查方向或者优化措施
