USB EZ-PD Type-C

[MiMu_4671456]

I've been trying for hours to get the CCG2 EVK to supply any voltage to an attached BCR board.

What am I doing wrong? I added PDOs for 5V/3A, 9V/3A, 15V/3A and 20V/5A and connected TP17 to TP20 as well as TP18 to TP21

I notice that the VBUS voltage jumps between 5V/9V/0V but no connection is possible.

in the meantime I found a very complex manual how to change the firmware here: Cannot programming CY4521

I did everything except "2) Update bootloader hex file in bootloadable components." as I have no idea what that means.

The code unfortunately doesn't compile:

Can you help me to get it to work? I attached my source to this post.

Also can I just upload the compiled firmware the same way I uploaded the default firmware when first using the eval kit?

Hi,

Please deselect the hardware connection option in the configuration settings for the added VSEL pins. For updating the bootloadable, please refer to the Import EZ-PD Configuration Utility C-source

Yes, you could update the new .cyacd file using the EZ-PD Configuration Utility as with the default firmware.

Best Regards,
