Hi,
When I am reading the post "CCG3 charge through dongle firmware" I found the HPD signal in the firmware setting file "noboot.cywr" does not seem to match the schematic. As in schematic it is connected to pin 35 but it is set at pin 9 in the firmware.
Please check and confirm.
Solved! Go to Solution.

Hi Ben,
If you are gong to develop a CCG3 charge through dongle, please assured that you are using the example code from CCGx SDK v3.0.2. (LINK: ). And you need to noticed that CCG3 charge through dongle firmware project is not includes bootloader part. And Cypress do not release those bootloader project out. The thread CCG3 charge through dongle firmware is specified firmware design which is customized firmware from notebook example code. That's why you see the I2c bootloader project.
Best Regards,
Lisa
