basically you never want to care about chg_curlim as it is a maximum of 1C = 1.2A for GTA01/02 battery cell and you never can draw that much current from USB (The PMU allows for a maximum of 1A here). PMU is automatically handling the distribution of available USB current between charging and system in a way system always has priority and chrg current reduced accordingly - so no need to care about chg_curlim for that topic either. cheers jOERG
