Is it possible to make or dump NVRAM data as a separated hex file and write the file to CYW20819?
For mass production, we would like to separate firmware file and setting file, that is different per customers.
And could we download/write a firmware without deleting NVRAM information?

Hi ToKo_4602001 ,
A similar procedure which is called as a FW upgrade over HCI UART will be available from BTSDK 2.9 which will be released next month.
If it is urgent for you or want more details on this immediately, please contact your local Cypress FAE / distributor and create an internal case for the same.
Thanks & Regards,
Anjana

Hello ToKo_4602001 ,
Do you mean you want to download / write a FW without deleting the VS section of onchip flash (where we save Bonding information , other data which have to retained after power cycle) ?
Please confirm / clarify the requirement.
