VEYE IMX327S适配firefly主板问题

qianjunzhou

使用Firefly aio-3588sjd4主板，30pin mipi dphy接口，按照wiki添加了.c改了驱动目录下的kconfig、makefile,改了dtsi，但仍识别不到摄像头，用dmesg| grep veye没有查到驱动信息，请问如何解决排查

qianjunzhou

firefly_linux.config也改了，把摄像头=y了

@qianjunzhou
需要分成三部分：

驱动是否编译到系统中了？
dts是否正确加载了？
硬件i2c是否能检测到了？

我初步比较怀疑的是第二步。 AIO系列使用的dts文件必然与我们做过调试的ROC不是一个上层文件。因此你要首先确认原来系统用的哪个dts文件，然后将camera的定义在相应的文件中引用。

qianjunzhou

@veye_xumm 1.驱动目录下的Kconfig、Makefile已经更改，也生成了veyecam2m.o文件。firefly-linux.config中也添加了相应的驱动开关，然后用firefly的build脚本编译固件
2.我就是在原来的dts中include了veye的dtsi文件，并注释了原本的摄像头dtsi
3.没有驱动信息

@qianjunzhou
关于dts的改动，请提供更多信息。
你现在只说你所有步骤都做对了，但是结果不对。我是没办法帮你分析的。

veye_xumm

@qianjunzhou 看起来dts应该是在aio-3588sjd4.dts改动一下，包含veyecam的dtsi就可以，逻辑关系还是比较清晰的。

qianjunzhou

这是aio-3588sjd4.dts文件，其中include了两个官方摄像头的dtsi文件，我将aio-3588sjd4-cam-8ms1m.dtsi这个文件的内容替换成了贵司的rk3588-roc-pc-cam-veyecam2m.dtsi的内容
下面是3588sjd4-cam-8ms1m.dtsi这个文件的原内容

开机后，使用dmesg | grep veye会有如下报错

qianjunzhou

@qianjunzhou 好像是I2C不对，这个板子dphy是用I2C5

veye_xumm

@qianjunzhou
rk3588-roc-pc-cam-veyecam2m.dtsi
中有一些资源信息，需要根据底板不同而调整。比如i2c,io等。

qianjunzhou

@veye_xumm 感谢回复，目前我主板的DPHY上使用贵司的摄像头已经成功了，我的主板只有一个dphy摄像头接口，还剩下两个DCPHY接口但是是24pin的，我想自己画转接板将接口转换一下，但不知道一个主板上能否同时使用两个VEYE的摄像头，是否会有冲突或者别的问题，希望得到您的答复

veye_xumm

@qianjunzhou 如果主板设计没有问题，那么每一个mipi csi-2接口的硬件资源都是独立的。也就是说，你的3个mipi csi2接口可以接3个摄像头。驱动中需要做的就是dts中区分定义三套资源。

@qianjunzhou said in VEYE IMX327S适配firefly主板问题:

还剩下两个DCPHY接口但是是24pin的

此外，你这个地方提到的DCPHY指的是这两个接口兼容DPHY和CPHY模式对吗？如果对，则无问题。
