xavier nx平台调试多路imx274视频通路
1. 前言
试图使用三个IMX274相机模块与Xavier NX,
但得到以下错误
[ 55.932842] tegra194-vi5 15c10000.vi: [vi capture status] csi_port 0, stream_id 0, channel_id 1, virtual_channel_id 65535
[ 55.933086] tegra194-vi5 15c10000.vi: no reply from camera processor
[ 55.933208] tegra194-vi5 15c10000.vi: vi capture get status failed
目前使用的是JetPack 4.4。
看起来I2C通信是正常的,
但试图从CSI端口读取时会超时

没有从MIPI总线接收任何验证数据。
可能需要探测MIPI信号和检查CSI通道配置匹配HW连接
检查跟踪发现下面的错误,表示rx FIFO溢出。

3. 调整Pix_clk_hz & 时钟
根据之前的经验
可以尝试调整Pix_clk_hz
以及nvcsi和vi时钟
(1)修改Pix_clk_hz & mcLk_multiplier
设备树中修改了以下值:
Pix_clk_hz从576000000到756000000
McLk_multiplier从24到25
(2)调高了nvcsi和vi时钟
echo 998400000 > /sys/kernel/debug/bpmp/debug/clk/vi/rate
echo 1190400000 > /sys/kernel/debug/bpmp/debug/clk/isp/rate
echo 400000000 > /sys/kernel/debug/bpmp/debug/clk/nvcsi/rate
但看起来这些值被限制在以下几个方面:
cat /sys/kernel/debug/bpmp/debug/clk/vi/rate
460800000
cat /sys/kernel/debug/bpmp/debug/clk/isp/rate
576000000
cat /sys/kernel/debug/bpmp/debug/clk/nvcsi/rate
314000000
按照上述修改后
仍然无法采集
查看trace也是一样
另一个潜在的信息来源:
运行如下命令
v4l2-ctl -d /dev/video0 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=3
[ 221.009649] tegra194-vi5 15c10000.vi: [vi capture status] csi_port -1, stream_id 65535, channel_id 0, virtual_channel_id 65535

[ 221.012389] tegra194-vi5 15c10000.vi: err_rec: successfully reset the capture channel
奇怪的是,csi_port一直报错是-1
可能原因是设备树的port匹配错误了

模式0的分辨率设置为3840X2160,
但我已经尝试了很多不同的分辨率
(模式1= 1920x1080,模式2= 1280x720,模式3= 1280x540)
5. 启用dev_dbg()来确认端口映射
使用以下命令启用了dev_dbg()消息:
echo 'file channel.c +p' > /sys/kernel/debug/dynamic_debug/control
echo 'file csi4_fops.c +p' > /sys/kernel/debug/dynamic_debug/control
echo 'file csi2_fops.c +p' > /sys/kernel/debug/dynamic_debug/control
trace信息如下
gst-plugin-scan-6821 [000] .... 79.146174: tegra_channel_open: vi-output, imx274 30-001a
gst-plugin-scan-6821 [001] .... 79.147665: tegra_channel_set_power: imx274 30-001a : 0x1

6. 检测设备树port匹配
用示波器检查了信号,看起来没问题。
此外,实际上能够使3个IMX274摄像机工作,
但必须在模式配置中将num_lanes改为2而不是4。
如果我把它们设置为4,就不会像在之前的帖子中显示的那样工作。
现在的设备输入port匹配如下:
host1x {
vi@15c10000 { // Video Input: this is the port binding
/* CSI Channels */
num-channels = <3>; // Number of video inputs
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 { // media pad port
reg = <0>;
liimx274_vi_in0: endpoint {
port-index = <0>; // sensor port connection
bus-width = <4>; // number of CSI lanes. Each CSI port has 2 CSI lanes, so there are 12 lanes total.
remote-endpoint = <&liimx274_csi_out0>; // This binds the two ports. One is for sink and one for source
};
};
port@1 {
reg = <1>;
liimx274_vi_in1: endpoint {
port-index = <2>; // sensor port connection
bus-width = <4>; // number of CSI lanes. Each CSI port has 2 CSI lanes, so there are 12 lanes total.
remote-endpoint = <&liimx274_csi_out1>; // This binds the two ports. One is for sink and one for source
};
};
port@2 {
reg = <2>;
liimx274_vi_in2: endpoint {
port-index = <4>; // sensor port connection
bus-width = <4>; // number of CSI lanes. Each CSI port has 2 CSI lanes, so there are 12 lanes total.
remote-endpoint = <&liimx274_csi_out2>; // This binds the two ports. One is for sink and one for source
};
};
};
};
// sensor -> (port0)NVCSI(port1) -> (port#)VI
nvcsi@15a00000 {
num-channels = <3>;
#address-cells = <1>;
#size-cells = <0>;
channel@0 {
reg = <0>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
liimx274_csi_in0: endpoint@0 {
port-index = <0>; // sensor port connection
bus-width = <4>; // number of CSI lanes. Each CSI port has 2 CSI lanes, so there are 12 lanes total.
remote-endpoint = <&liimx274_imx274_out0>; // This binds the two ports. One is for sink and one for source
};
};
port@1 {
reg = <1>;
liimx274_csi_out0: endpoint@1 {
remote-endpoint = <&liimx274_vi_in0>;
};
};
};
};
channel@1 {
reg = <1>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
liimx274_csi_in1: endpoint@2 {
port-index = <2>; // sensor port connection
bus-width = <4>; // number of CSI lanes. Each CSI port has 2 CSI lanes, so there are 12 lanes total.
remote-endpoint = <&liimx274_imx274_out1>; // This binds the two ports. One is for sink and one for source
};
};
port@1 {
reg = <1>;
liimx274_csi_out1: endpoint@3 {
remote-endpoint = <&liimx274_vi_in1>;
};
};
};
};
channel@2 {
reg = <2>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
liimx274_csi_in2: endpoint@4 {
port-index = <4>; // sensor port connection
bus-width = <4>; // number of CSI lanes. Each CSI port has 2 CSI lanes, so there are 12 lanes total.
remote-endpoint = <&liimx274_imx274_out2>; // This binds the two ports. One is for sink and one for source
};
};
port@1 {
reg = <1>;
liimx274_csi_out2: endpoint@5 {
remote-endpoint = <&liimx274_vi_in2>;
};
};
};
};
};
};
我使用的是来自Leopard Imaging的imx274驱动程序和传感器初始化表。
我以为他们使用的是四车道传感器配置
tegra194-camera-imx274-dual.dtsi
dsi在那里都使用总线宽度4
我想找到了问题的根源。
imx274_mode_tbls.h实际上是为2 lane配置的,
而设备树是配置的是4lane的配置
所以需要更新4lane的sensor配置文件即可
解决办法:
更新imx274.h, imx274.c,和imx274_mode_tbls.h)为4道配置,
现在我的相机工作。
问题:
图像看起来很模糊,
尝试调试过饱和度,tnr模式,e-mode和wbmode,但仍然很模糊
镜头是干净的,它实际上没有雾在房间里。
有三个摄像头,它们都是这样出现的。
这是命令:
gst-launch-1.0 nvarguscamerasrc sensor-id=0 sensor-mode=0 wbmode=8 saturation=2 tnr-mode=2 ee-mode=2 ! nvvidconv ! queue ! xvimagesink sync=false
解决办法:
更新isp文件
/var/nvidia/nvcam/settings/
现在三路imx274的图像出图正常了
