Serial Bootloader all-in-one?

[Constantin]

Hi,

is there a way to make a all in one bootloader image which includes Softdevice and APP in one zip? And is there an example of the DFU via a Master uC. My setting is that I have a Main CPU (STM32F4) which is connected via FTDI to a PC and should manage the DFU.

Best regards,

Constantin

Hi Constantin,

Yes, it is possible to create a combined SoftDevice and Application image using nrfutil. Assuming that you're using our Secure Bootloader. SDK v12.0.0 and later) the allowed combinations are shown in the below, which also is shown in the nrfutil documentation.

I am afraid that we do not have any example code for implementing the DFU Controller on a Host MCU, there are simply to many differnet options to cover them all. I suggest that you take a look at the documentation of the DFU Serial Transport Layer, found here.

Best regards
