===============================================
I guess it may be due to the following reasons
I want to ask if my statement is correct
Because I want to communicate with ub962
It uses I2c4 to communicate with tda board and My core is to use ipu1
-----------------------------------------------------------------------------------------
Q1:How do I know if I have i2c enabled?
-----------------------------------------------------------------------------------------
Q2:Because it looks like the IRQ between TDA Board and Ub962 can’t communicate
So are there other possible errors that I haven't noticed?
Thanks all !!!
