@wuming 现在可以找代理商下单了。

RE: Coolpi support 32GB of RAM
@HU The CP4 machine currently does not have a 32GB RAM version. We will soon launch a CP4-PRO machine that can replace DDR particles and WIFI modules, and can support up to 32GB RAM

RE: 连接器型号
@qys2022 下面是MXM连接器规格书和对应的贴片铜螺母,封装都是一样的,按照板子的实际高度选择不同规格。

RE: ubuntu 0306 有时桌面卡死
-
目前跟踪到的问题是,视频窗口全屏状态下,gnome会发afbc的图层格式给VOP,但这种格式是VOP Esmart图层不支持的类型,内核监测到这种异常图层就会报不支持的log,屏蔽掉出错log浏览器视频播放不会有影响。
-
然后测试了QV4L2打开摄像头然后全屏,没有发现黑屏的现象,可以参考一下QV4L2的全屏操作方式。

RE: Ubuntu23.04 for CoolPi
@wuming 确认loader有没有更新到最新,先连接USB到电脑,然后短按rst一次,然后按三次PWR按键,机器就会进入UMS模式。

RE: Coolpi uses UMS to update the system
@Twsuts 这个固件是百度网盘或者onedrive下载的系统img格式固件。不是内核编译脚本生成的。

RE: ubuntu 0306 有时桌面卡死
@jugg 数据格式NV12是没有问题的,这里主要是Esmart图层本身不支持AFBC的格式。可以尝试图层切换到Cluster显示,但是我查了一下AFBC的格式,好像也没有AFBC_FORMAT_MOD_SC这种,你可以先尝试一下.

RE: ubuntu 0306 有时桌面卡死
@george 刚才查了一下0351对应如下格式,这种格式RK3588 VOP是支持不了的,所以画面会异常。确认一下SDL过来的数据格式是否可以修改为VOP支持的格式。

RE: CSI支持
@wuming 这个接口意义非常大,直接驱动4个摄像头可以做360环视。再加转换芯片以后可以做到8个摄像头同时工作。后续如果有这方面需求可以提出来,我们会有针对性的出一些转接小板。
