Hi,
One of my customer using BQ27200 with AM335x and facing some issues.
We are testing BQ27200 fuel gauge with AM335x in our custom board. When we interface fuel gauge with the board, system gets hanged immediately after booting. I have logged the values that driver reads from the fuel gauge before it hangs. I have attached the system boot log for your reference. Last few lines in the log shows the values read from the fuel gauge and system halted messages. This happens only when we interface bq27200.
Attached log file, please help me on this.
