rk3568mipi攝像頭調(diào)試(gc2385 + gc2053)

這篇具有很好參考價(jià)值的文章主要介紹了rk3568mipi攝像頭調(diào)試(gc2385 + gc2053)。希望對(duì)大家有所幫助。如果存在錯(cuò)誤或未考慮完全的地方，請(qǐng)大家不吝賜教，您也可以點(diǎn)擊"舉報(bào)違法"按鈕提交疑問(wèn)。

RK3568平臺(tái)僅有一個(gè)標(biāo)準(zhǔn)物理mipi csi2 dphy,可以工作在full mode 和split mode兩個(gè)模式, 拆分為csi2_dphy0/csi2_dphy1/csi2_dphy2三個(gè)邏輯dphy

Full Mode:

僅使用csi2_dphy0,csi2_dphy0與csi2_dphy1/csi2_dphy2互斥,不可同時(shí)使用;

data lane最大4 lanes;

最大速率2.5Gbps/lane;

Split Mode:

僅使用csi2_dphy1和csi2_dphy2, 與csi2_dphy0互斥,不可同時(shí)使用;

csi2_dphy1和csi2_dphy2可同時(shí)使用;

csi2_dphy1和csi2_dphy2各自的data lane最大是2 lanes;

csi2_dphy1對(duì)應(yīng)物理dphy的lane0/lane1;

csi2_dphy2對(duì)應(yīng)物理dphy的lane2/lane3;

最大速率2.5Gbps/lane

雙目攝像頭鏈路連接：

gc2385->csi2_dphy1->isp_vir0

gc2053->csi_dphy2->csi2->cif->isp_vir1

雙攝像頭的時(shí)候，需要用到2個(gè)phy，因此需要只能用Split Mode。

一 .Full Mode單攝像頭dts配置如下：

gc2385/gc2053->csi2_dphy0->isp_vir0

三. 調(diào)試流程：

　　驅(qū)動(dòng)在kernel/drivers/media/i2c下，目前調(diào)的2385和2053sdk里面已經(jīng)存在，直接用該驅(qū)動(dòng)即可。

　　調(diào)試中的一些經(jīng)驗(yàn)總結(jié)：

　　3.1：首先要確保AVDD(2.8)、DVDD(1.2)、DOVDD(1.8)三路電壓正常出來(lái)。

　　3.2：reset、pwdn這兩個(gè)引腳是否正常配置到起作用，用示波器量信號(hào)

　　3.3：查看原理圖，確認(rèn)硬件連接上的對(duì)應(yīng)關(guān)系：2385：MIPI_RX_D0-1(csi2_dphy1) 2053：MIPI_RX_D2-3(csi_dphy2),這個(gè)地方要對(duì)應(yīng)上，不可調(diào)換過(guò)來(lái)　　

　　　　　　gc2385->csi2_dphy1->isp_vir0

　　　　　　gc2053->csi_dphy2->csi2->cif->isp_vir1

　　3.4：mclk配置查看原理圖是否對(duì)應(yīng)正確，RK356x有四個(gè)輸出時(shí)鐘，可作為給CIS模組的MCLK：

　　　　1、REFCLK_OUT（GPIO0_A0）

　　　　示例dts：arch/arm64/boot/dts/rockchip/rk3566-evb2-lp4x-v10.dtsi中的gc5025時(shí)鐘配置

　　　　gc5025: gc5025@37 {

　　　　.…..

　　　　clocks = <&pmucru CLK_WIFI>;

　　　　clock-names = "xvclk";

　　　　pinctrl-names = "default";

　　　　pinctrl-0 = <&refclk_pins>;

　　　　};

　　　　2、CAM_CLKOUT0（GPIO4_A7）

　　　　示例dts：arch/arm64/boot/dts/rockchip/rk3566-rk817-tablet.dts中的ov8858時(shí)鐘配置

　　　　ov8858: ov8858@36 {

　　　　.…..

　　　　clocks = <&cru CLK_CAM0_OUT>;

　　　　clock-names = "xvclk";

　　　　pinctrl-names = "default";

　　　　pinctrl-0 = <&cam_clkout0 >;

　　　　};

　　　　3、 CAM_CLKOUT1（GPIO4_A8）

　　　　示例dts：arch/arm64/boot/dts/rockchip/rk3566-evb1-ddr4-v10.dtsi中的ov02k10時(shí)鐘配置

　　　　ov02k10: ov02k10@36 {

　　　　.…..

　　　　clocks = <&cru CLK_CAM1_OUT>;

　　　　clock-names = "xvclk";

　　　　pinctrl-names = "default";

　　　　pinctrl-0 = <& cam_clkout1>;

　　　　};

　　　　4、 CLK_CIF_OUT （GPIO4_C0）

　　　　示例dts：arch/arm64/boot/dts/rockchip/rk3566-rk817-tablet.dts中的gc2385時(shí)鐘配置

　　　　gc2385: gc2385@37 {

　　　　.…..

　　　　clocks = <&cru CLK_CIF_OUT >;

　　　　clock-names = "xvclk";

　　　　pinctrl-names = "default";

　　　　pinctrl-0 = <& cif_clk >;

　　　　};

　　　　這里我用到的兩組是：

　　　　2053：REFCLK_OUT（GPIO0_A0） 2385：CLK_CIF_OUT （GPIO4_C0）

3.5：確保i2c地址正確，如果以上4點(diǎn)都正常，這時(shí)候應(yīng)該就可以正常識(shí)別到sensor id了?？梢赃M(jìn)行正常的mipi信號(hào)傳輸，可用v4l2 命令獲取數(shù)據(jù)流：　　

　　　v4l2-ctl --verbose -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=BG10 --stream-mmap=3 --stream-skip=100 --stream-to=/tmp/GB10.raw --stream-count=1 --stream-poll

　　　v4l2-ctl --verbose -d /dev/video5 --set-fmt-video=width=1600,height=1200,pixelformat=BG10 --stream-mmap=3 --stream-skip=100 --stream-to=/tmp/GB10.raw --stream-count=1 --stream-poll

　　3.6：此時(shí)打開(kāi)apk，如果還打不開(kāi)，使用命令：dumpsys media.camera

　　Number of camera devices: 0，說(shuō)明 framework 層沒(méi)有識(shí)別到攝像頭，這個(gè)一般是camera3_profiles.xml中對(duì)應(yīng)攝像頭沒(méi)有配置或者配置不對(duì)導(dǎo)致異常

　　開(kāi)機(jī)過(guò)程會(huì)有以下log：

　　rockchip-csi2-dphy csi2-dphy1: dphy1 matches m01_f_gc2385 2-0037:bus type 4

　　rockchip-csi2-dphy csi2-dphy2: dphy2 matches m00_b_gc2053 3-0037:bus type 4

　　cat /sys/class/video4linux/*/name或者：

　　m0x這個(gè)對(duì)應(yīng)的是dts中的配置：

　　rockchip,camera-module-index = <x>; x:0/1

　　我調(diào)試的時(shí)候，識(shí)別不到設(shè)備，就是camera3_profiles.xml中2385的moduleId與驅(qū)動(dòng) DTS 中配置不一致導(dǎo)致的。

　　這時(shí)再dumpsys media.camera：

　　Service global info:

　　Number of camera devices: 1

　　Number of normal camera devices: 1

　　Number of public camera devices visible to API1: 1

　　說(shuō)明識(shí)別到設(shè)備了

　　3.7：第6點(diǎn)正常后，但是使用 APK 還是打不開(kāi)，這種情況一般是tuning效果文件導(dǎo)致，這種情況只有raw攝像頭sensor需要iq文件。

　　raw攝像頭支持的iq文件路徑external/camera_engine_rkaiq/iqfiles/isp21, 與以前不一樣的地方是iq文件不再采用.xml的方式，而是采用.json的方式。

　　rkisp : [XCORE]:XCAM ERROR RkAiqCalibDbV2.cpp:322: access /vendor/etc/camera/rkisp2/gc2053_RS-D22WS14P-1_default.json failed!

　　需要注意的是，這個(gè)json文件命名也是跟dts一致的，不然匹配不上：

　　gc2053_default_JX8006.json

　　rockchip,camera-module-name = "default";

　　rockchip,camera-module-lens-name = "JX8006";

　　3.8:經(jīng)過(guò)以上的艱辛路程，兩個(gè)攝像頭終于可以打開(kāi)了。經(jīng)過(guò)跟廠家確認(rèn)，gc2053的是RGB的彩色鏡頭，gc2385是IR的紅外鏡頭，但發(fā)現(xiàn)gc2053的出圖是灰白色的，經(jīng)過(guò)跟rk工程師的溝通，需要再iq文件里面修改一下顏色的反色：

　3.9:默認(rèn)打開(kāi)前置、后置攝像頭：

　　　　packages/apps/Camera2/res/value/strings.xml里設(shè)置pref_camera_id_default為1即默認(rèn)打開(kāi)后攝，為0即默認(rèn)打開(kāi)前置

　　3.10：到此，攝像頭就正常了。文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-577384.html
