Hi Mike:
thank you reply me ! I set the address is 0x100000,but it can run but will crash after seviral second!
if you have test the driver bfin_ad7179_i2c which is in the forum upload by user, I download from the forum,but it's I2C not work,can not find the 0x54 address,perhaps ,I should set some parameter in the config,but I dont know what should be set( I have choose the I2C and gpio I2C),the ADV7183 I2C can work correct,why 7179 I2C can not ?
can you give me some advise !
