Hi,

CYUSB4347 and CYUSB4357 are 2 different MPNs. 

May I know which device did you select under device item? It appears as per the error, there is a mismatch between the selected device and the project.

Regards,

Mallika

Hi,

In general, after modifying the application part number, the corresponding bootloader binaries should also be updated. This is done by clicking on the Bootloadable component present in the schematics tab. There you need to update the bootloader binary files in the Dependencies tab.

However, for CYUSB4357, the bootloader files are not present in the SDK. So, in your case, when you have selected the device under the device sector as CYUSB4357, the bootloadble project now points to CUSB4357 but the bootloader still points to CYUSB4347. 

Could you please let us know if you wish to use CYUSB4357 and signed firmware update?

Regards,

Mallika

Thanks a lot , Mallika .

Yes, we need to use CYUSB4357 and signed firmware update. The reason is that the sample ic obtained by the customer is CYUSB4357, and its corresponding Firmware is required to verify the function of the board. For customers, it is hoped that both CYUSB4347&4357 can be used, which is convenient for material preparation.
Please help us to get the relevant information, thank you.
