@kevin2008 生成video节点只能表明i2c通了。 看你的截图，像是mipi接收部分的配置不对。

@red Hi, I didn't understand your meaning. Yocot is a project management tool, right? The demo we provided is just on the wiki and is not integrated with Yocot.

@yukang-zhong 你好，现在已经lock上了，但是显示camera没有数据发出 i2c命令读camera也没有数据，显示不可读，请问一下需要怎样设置camera,camera才有数据出来 我们的连接如下ds90ub954对应的部分，我们是ds90ub962 #/-------------------\ /----------------------\ /--------------------\ /------------------ #| MIPI CSI RECEIVER | | FPDLINK DESERIALIZER | | FPDLINK SERIALIZER | | MIPI CSI CAMERA | #+-------------------+ CSI +----------------------+ +--------------------+ CSI +------------------+ #| | <----- | | Coax | | <----- | | #| Raspberry Pi (4) | GPIO | fpdlink2raspi | <----> | piCam2fpdlink | GPIO | Raspberry Pi | #| Jetson Nano | <----> | PCB | | PCB | <----> | Camera Module v2 | #| ... | I2C | ds90ub954 | | ds90ub953 | I2C | | #| | <----> | | | | <----> | | #-------------------/ ----------------------/ --------------------/ ------------------/ ID ADDR (7BIT) 0x30 0x18 0x3B(VEYE CAMERA) ID ADDR (8BIT) 0x60 0x30 0x76(VEYE CAMERA) ALIAS ADDR (7BIT) NA 0x19 0x3B(VEYE CAMERA) ALIAS ADDR (8BIT) NA 0x32 0x76(VEYE CAMERA) i2cdump -f -y 7 0x18 No size specified (using byte-data access) 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 00: 30 00 73 48 00 03 43 fa fe 1e 10 7f 7f d2 2d 00 0.sH.?C???????-. 10: 00 00 00 00 00 20 18 3c 80 62 62 62 00 00 00 00 ..... ?<?bbb.... 20: 00 00 00 00 00 02 00 00 67 33 01 00 00 00 00 00 .....?..g3?..... 30: 00 20 09 04 00 10 00 60 00 00 00 00 00 00 00 00 . ??.?.`........ 40: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 50: 20 c0 45 0d 00 00 00 00 07 07 07 00 ff 00 44 00 ?E?....???...D. 60: 00 00 00 00 00 c8 00 00 00 00 00 00 00 00 00 00 .....?.......... 70: 00 00 25 00 00 00 00 00 00 00 e4 00 00 00 00 00 ..%.......?..... 80: 00 00 00 00 00 00 90 00 00 00 00 00 06 00 00 00 ......?.....?... 90: 32 e3 64 01 00 00 00 00 00 00 03 01 00 00 27 0e 2?d?......??..'? a0: 00 0d 0f 0e 0d 10 42 10 10 10 03 01 00 00 00 00 .?????B?????.... b0: 04 4a 3f 00 00 00 00 00 00 00 00 00 00 00 00 00 ?J?............. c0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ d0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ e0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ f0: 5f 55 42 39 35 33 00 00 00 00 00 00 00 00 00 00 _UB953.......... root@j7-evm:/app# i2cdump -f -y 7 0x3b i2cdump -f -y 7 0x3b No size specified (using byte-data access) 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 00: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 10: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 20: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 30: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 40: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 50: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 60: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 70: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 80: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 90: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX a0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX b0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX c0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX d0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX e0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX f0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 请问0x3b是sensor的地址，还是isp的地址，此时953可以访问，0x3b不可以，是表明953没有配置对 sensor或isp嘛

@veye_xumm Thank You . I try today .

@sakura 不是的，摄像机的版本。 你用的什么型号的摄像机？

@chjchoi I think this place means that the 954 chip is not detected properly on the i2c.

@chjchoi I tried to send you an email , but it bounced back. Please confirm this email address.

@dmmoskalev Great!

Jetson TX2 (JetPack 4.4)+ FPD LINK III for Jetson of VeYe's After modifying ADP-N3 according to ADP-N2 pin map...

@sophiajackson22 Thank you for the information, I will keep an eye on it.

@laks said in FPD-LINK3-2RX need a 12V DC power.: Can u provide specification for 12V DC supply. Also if there is any specific part number to buy. Using the most common and ordinary 12V DC power adapter is fine.

@ledzhongzi 不客气

@g-towboat Our solutions are 953 and 954 and the source code of the driver is provided. You can refer to this source code to support 964. Now fpdlink products have been suspended due to chip out of stock, sorry.

@veye_xumm ok i am understand, just these three formats thank you

@wqeeqweqwwccsd 已经收到了，同事在处理中。下周初会发回给你。

@wqeeqweqwwccsd said in 修改FPS问题: ，请问这样可行吗？ 不可行，sync模式不支持的。会自动跳回默认帧率。

@wqeeqweqwwccsd 你这种测试方法是极为模糊和不确切的。请参考我上一个帖子发给你的链接。

@wqeeqweqwwccsd 当然是支持的。你可以看这篇文章 6.3 6.4两个部分。 http://wiki.veye.cc/index.php/FPD_LINK_III_for_Jetson/zh 其中，6.4 xavier的典型案例就有实现了同一颗954连接的两路视频的同步。

@yongjin I don't know what your current state of knowledge is. If you don't understand i2C, you don't understand fpdlink, you don't understand registers. I think you should first learn the basics and be able to understand the information and code we provide now, and then proceed to your next work. Good luck.

@robot nano现在只能支持2个摄像头。 核心的限制因素是： nano这颗cpu，不支持mipi的虚拟通道。也就是说两路视频融合到一个mipi通路中进入cpu，这个功能，nano是支持不了的。
