@Raj: Please state clearly which device type , the bootloader device type, application device type or actual hardware device type was send. And "send" here mean ?

Basically there is only one checking step, when the bootloader receive the application DFU image , it will check in the init data of that application DFU image if the device type inside that is equal to the device type it has inside its code.

So you either modify the bootloader to correct device type, or you modify the application device type when you generate the application DFU packet to match with your bootloader 's device type.

Hi Hung, by mistake we send our custom boards with device type 0x01 but the actual device type is 0x02. so we need to update that boards to device type 0x02.

Hi Raj,

Why do you want to update an application which has device type = 1 using a bootloader which has device type = 2 ?

When the new bootloader start, it will expect to receive application with device type = 2.
