Hi ,
Q1: what steps we need to do in order require ability FW update via power board ?
Make sure the Power board configuration is same as the bootloader you are going to upgrade. For example, the example project have two types of bootloader:
cc_sink
cc_source.
The cc sink means of the CCG3PA is going to working as power sink role when attached with power board. The cc source means of the CCG3PA is going to working as power source role.
------------------------------------------------------------------------------
Since you are using cc_source bootloader, you should make sure the 5V on VBUS could be controlled correctly on CCG3PA with bootloader mode. Which is meaning of VBUS shall be 0V at un-attached mode, and then CCG3PA advertise 5V/900mA source cap on CC and enable 5V on VBUS.
Q2: does bootloader we use support "bootloading via cc lines" feature if not please provide or we need implement one?
>> The cc bootloader have been implemented in the CCG SDK, there is no need to additional implementing.
Best Regards,
Lisa
