Dear Cypress team,

Recently we want to use the F/W upgrade feature using the "OTA_FirmwareUpgrade" application.

But this sample application is not working on the customer board.

I found the reference board is working fine.

After comparing two board and review the sample application, I assumed this application uses the external memory for upgrading.

So could you let me know how to support the OTA firmware upgrade feature without external memory?

I do not do anything on the OTA firmware upgrade sample code.

Please guide the patch based on that sample code.

Regards,

Wayne

Dear all,

We've find this issue is resolved by below:

========================================

remove OTA_FW_UPGRADE_SFLASH_COPY, ENABLE_SFLASH_UPGRADE features in build config.

And add the OTA_FW_UPGRADE_EFLASH_COPY in build config.

Regards,

Wayne

Hello Wayne,

Could you please confirm which Cypress Chip are you using?

Are you using a custom board or any Cypress Eval board?

Hi Anjana

Sorry for the confusion.

We use 89820 for our project.

And we can reproduce this issue on the customer board.

But I think we could reproduce this issue in the reference board without external memory.

Wayne
