SOLVED 相机抓图相关问题

我尝试做转接板让edge2开发板支持raw-mipi-sc132m相机。
编译好驱动后，更改设备树如下：// SPDX-License-Identifier: (GPL-2.0+ OR MIT) / { vcc_mipidphy0: vcc-mipidcphy0-regulator {//cam2-sc132m status = "okay"; compatible = "regulator-fixed"; gpio = <&gpio1 RK_PB2 GPIO_ACTIVE_HIGH>;

@潘阳刚 这个问题有可能是edge2的linux kernel 源码缺少一些对数据格式的支持。
kernel\drivers\media\platform\rockchip\cif\capture.c
附件这份代码，你聊做参考。

@veye_xumm 确实缺少支持，我修改了这个文件。重新烧录镜像之后再次尝试，现在的log是这样的：

@潘阳刚 感觉你现在问题更麻烦了。 上次给你的文件，不能直接替换掉，你从中把关于数据类型的几个地方修改到原来edge2的源码中即可。
-
capture.txt @veye_xumm 我没有直接替换，原始文件和您给我的文件只有如下几处不一样，我进行了修改：
绿色的几行本不在原始文件中。
其他有区别但是我未作改动的：
其他的都一致。现在的问题有没有可能是转接板PCB设计不恰当导致的？
capture.txt -
@潘阳刚 整体上我看你的操作没有太大问题。 现在不出图，不太清楚是咋回事。 要不你把板子寄过来，我们给看一下吧。
-
@veye_xumm 地址是什么？
