@veye_xumm 是把Xavier下载的dtb文件拷贝到Host pc 的/kernel/dtb/文件里，然后在执行flash脚本就ok了？

[veye_xumm]

@wzy
是的，详细步骤请参考wiki

[wzy]

@veye_xumm
执行dmesg | grep veye327 后的结果，是这样的。是哪出了问题吗？

[veye_xumm]

@wzy 我看你用的是fpdlink接口的327，应该用fpdlink目录下的dtb文件。

[wzy]

@veye_xumm said in 签名文件:

fpdlink目录下的dtb文件
这个文件的路径在哪？拷贝到host pc，再烧一遍？

[veye_xumm]

@wzy
在github的dtb目录，如图。上面这个fpdlink的指的是veye327-fpdlink的型号。 你需要用这个目录下的dtb。

[wzy]

@veye_xumm
怎么没找到啊？你给复制个完整的git地址

[wzy]

@wzy
我用4.4的版本试过了，还是报的这个错！测试脚本也没有跑起来。

mogo@mogo-desktop:~/nvidia_jetson_veye_bsp/i2c_cmd/bin$ ./veye_mipi_i2c.sh -r -f devid
-bash: ./veye_mipi_i2c.sh: Permission denied

报错

[veye_xumm]

@wzy

请参考这个，注意提供12V供电，注意fpc排线方向。

-bash: ./veye_mipi_i2c.sh: Permission denied

这个要加一个可执行权限

chmod +x *

主要为了将参数配置到特定的camera，要用-b [busnum]参数，-d [address]参数。

还是报那个错误！

@wzy
把整个dmesg打印的东西导出来保存到文件里面，作为附件贴上来看一下。

[veye_xumm]

@wzy

sudo i2cdetect -r -y 33

结果如何

[wzy]

@veye_xumm 没有变化，还是那样。

[veye_xumm]

@wzy
执行一下上个帖子的命令，结果发给我

[wzy]

@veye_xumm

[veye_xumm]

@wzy
dmesg 不要加grep，把整个输出都保存起来。作为附件发上来看看。

[veye_xumm]

@wzy
fpdlink另一头，摄像头插上了吗？ 热乎不？

[wzy]

@veye_xumm 无权限添加文件

[veye_xumm]

@wzy

dmesg | grep ds90

贴一下这个结果。
