1.On my board, AM1808 I2C0 chain has 7 devices, and the test finds that the start position of SCL/SDA rising edge oscillates , as shown in Figure 1.
2.Then, I made I2C0 only direct to one slice EEPROM by flying lines and found that SDA/SCL oscillation was more severe, as shown in Figure 2.
I don't know why it is like this, please help to analyze it, thanks.
