We are using i.MX6ULL and BQ25703A for charger detection.
We are following steps specified in "i.MX 6ULL Applications Processor Reference Manual, Rev. 1, 11/2017" at page no 3910.
After setting "EN_B = 0, CHK_CHRG_B = 1 and CHK_CONTACT = 1" bits of CHRG_DETECTED register, we are monitoring PLUG_CONTACT bit of USB1_CHRG_DETECT_STAT register.
But when we connect USB cable to, dedicated charger it read low (i.e. 0) and it read high (i.e 1). which is not as per expectation as per defined flow in reference manual.
Please suggest us step to detect the dedicated charger, charging through PC/Laptop and data transfer to the pc/laptop.
Thank you in advance.
