I've bought CX3 MCU chip. It is marked as CYUSB3065, but bootloader is for SD3 (see screenshot). Does anybody faced with this problem? Is it possible to fix it?Wrong_Bootloader.jpg

Please check the PMODE1 pin connection. It might be floating. It should be pulled up. Once the PMOde settings are correct, the CX3 bootloader will come up as a FX3 Bootloader Device with the VID:04B4 and PID:00F3
