这样就可以了

int ISP_RGB_GREY(int chnID, int Grey) { RTIspCtrlAttr isp_ctrl_attr; if(Grey == 0){ isp_ctrl_attr.isp_attr_cfg.cfg_id = RT_ISP_CTRL_IR_STATUS; isp_ctrl_attr.isp_attr_cfg.ir_status = 0; } else{ isp_ctrl_attr.isp_attr_cfg.cfg_id = RT_ISP_CTRL_IR_STATUS; isp_ctrl_attr.isp_attr_cfg.ir_status = 1; } AWVideoInput_SetIspAttrCfg(chnID, &isp_ctrl_attr); usleep(500*1000); return 0; }

卡烧录需要在uboot阶段完成，但是快启流程是BROM-BOOT0-Kernel，跳过了uboot阶段，所以USB烧录的时候需要通过物理的方式进入烧录，但卡烧录用同样的方式也不能进入烧录，所以要怎样操作呢？

echo on > /proc/sys/kernel/printk_devkmsg 后重新运行

在make kernel_menuconfig打开inotify即可

重新烧录，可以看到有多个守护进程， 怎么把多余的关掉呢？

原来是室内信号受干扰了，放到室外就正常了

@whycanservice 👌 ,了解，谢啦~

@daizebin 安装后可以编译了。
但报了新的问题

@whycanservice 量化工具好像没有适配cuda，用不了GPU

编译一个ncnn直接cpu跑

@whycanservice 在 v831刚上电没有log打印，到了kernel阶段才有 中说：

@cruise33 uboot也需要修改，修改uart index

参考了这个精华帖

BOOT0的打印 和烧录时的打印到底受哪里控制..

@cruise33 烧录时候用的

@lijinlin001 uboot的dts当时没太留意，功能开启是在uboot/common/main.c里配置的，大概是这样：

#include <pwm.h> void pwm_init(void) { int pwm1; pwm1 = pwm_request(1, "pwm1"); pwm_config(pwm1, 500000, 500000); pwm_set_polarity(pwm1, PWM_POLARITY_INVERSED); pwm_enable(pwm1); }

具体的接口函数用法看uboot的pwm.h

找到了，在uboot的defconfig里定义

@cruise33 请问是那部分预处理的问题啊？我也遇到类似的问题

@cruise33

方案是busybox方式，make menuconfig

没记错的话应该是会自动挂到extsd上的

@whycanservice 取消勾选camerademo确实还会残留勾选VIN ISP，但已经都取消勾选了，也cleanmpp了（mp的怎么clean？），还是会报这个错

@biubiu 在 LVGL如何显示摄像头采集的数据? 中说：

@dybzz2 韦老师那边有参考：https://www.bilibili.com/video/BV1rF411f7Fw

你好，我看这个视频中韦老师写的代码，nv12 转 jpg的部分是使用的 cpu转化的，可以提供一下 g2d 转化的实现代码吗？

可以用yuv的查看器，大部分有这个功能

有没有只编一帧YUV成jpeg的demo啊😲

@cruise33 单推理，不仿真

@yuzukitsuru 工程属性->C/C++ Build->Settings->Tool Settings->GCC C++ Linker->Libraries，添加jpeg和ovxlib就行了，十分感谢！！
