gpio透传配置

Thread Summary

The user is troubleshooting an issue with the GPIO pass-through function between MAX96716 and MAX96717, where the MFP6 on the MAX96717 does not receive the correct FSYNC signal. The final answer suggests configuring the control end (MAX96716) for RX and the controlled end (MAX96717) for TX, and changing the delay to 8. The user confirmed that the control end refers to the MAX96716 and asked for clarification on enabling RX and the delay change.

你好!

我们现在使用max96716和max96717的GPIO透传功能,传输路径为:处理器产生fsync信号--》96716的MFP10--》GMSL2--》96717的MFP6--》sensor,目前的配置为:

//DES I2C Address=0x50

//SER I2C Address=0x84

//SER MFP6 Outputs FSYNC

0x84,0x02D0,0x84, // GPIO RX Tunnel Enabled, 1MΩ Pull-Down

0x84,0x02D1,0x66, // Pull-up, Push-pull, TX_ID=0x06

0x84,0x02D2,0x46, // RX_ID=0x06

 

//DES MFP10 Accepts FYSNC Signal

0x50,0x03E0,0x08, // FSYNC mode set to external

0x50,0x03EF,0x86, // FYSNC enabled on Pipe Y and Z

0x50,0x02CE,0x83, // GPIO TX tunnel enabled

0x50,0x02CF,0x66, // TX_ID=0x06

0x50,0x02D0,0x46, // RX_ID=0x06

但是现在96717的MFP6量不到正确的信号,请问是什么原因呢?

谢谢
