Hello,
CCG has two FW files (cyacd).
In SDK 3.3.1, ONE and TWO FW sizes are different.
Also, when performing File comparison, the data after Config Table data is completely different data.
CYPD3125-40LQXI_notebook_one_3_3_1_2010_0_0_0_nb.cyacd : 89KB
CYPD3125-40LQXI_notebook_two_3_3_1_2010_0_0_0_nb.cyacd : 145KB
In the previous SDK Version, it was the same size.
When I compared the data, it looked like the same data.
CYPD3125-40LQXI_notebook_one_3_2_1_1658_0_0_0_nb.cyacd : 131KB
CYPD3125-40LQXI_notebook_two_3_2_1_1658_0_0_0_nb.cyacd : 131KB
Q1) Why is the file size different in FW of the new SDK Version?
Q2) Why does the data look different in FW of the new SDK Version?
Best regards,
Kenji Takahashi

Hi Kenji,
If you have a chance to new created a project based on CCG3 notebook example code of SDK 3.3.1, you will found that the firmware project was changed.
The new project includes:
This is Dual asymmetric firmware architecture. The V3.2.1 is Dual symmetric firmware architecture. The difference is:
Dual asymmetric firmware architecture have a backup firmware on FW1, which have basic Type-C function. You can compare the config.h of both project, you will get below results:
Dual symmetric firmware architecture have totally same feature on both firmware.
Best Regards,
Lisa

Is it possible to switch from one to the other easily?
