Hi Haiwan,
Can you provide more information of the scope captures? What is Channel 1, 2, 3, and 4 in each scope capture?
Does each pair of output FETs have the same operation?
If it is just one, what is different about the one pair versus the other two?
1 -- What do you mean "please check if it is caused by interference"? What type of interference?
2--Can you provide both the SPI settings and the schematic from the DRV8305-Q1 to the FETs?
