Hello All,

i am working on IMX6ul board, in u-boot i2c Command is enabled,

but when i am giving i2c probe command through command line i am not getting all the valid chip address,

in logs i am receiving failure continuously.

Valid chip addresses  :

wait_for_sr_state : failed sr=81 cr=a0 state=2020

i2c init transfer : failed for chip 0xx0 retry=0

i am not getting why this failure is coming. 

Could anyone kindly provide us with some information on this. Any help on this is much appreciated.

Thank you.
