FDS function Implementation on DFU bootloader

Hi,

We do not have any examples of it (nor can I think of ever seeing it before), but I do not see any fundamental issue with using FDS in the bootloader nor anything in particular that should cause problems. The only think I think is worth mentioning is that you will increase the sizes of the bootloader this way, so you must move the bootloader start address down  a bit (I would guess one page). That is a general thing when adding functionality to the bootloader, though.

Hi Einar,

    You main the Flash address as below

Or have other seeting I need to verify.

Thnak you.

John,

Yes, this is the flash start address of the project you are building (I assume the bootloader in this case). Note that you cannot change the bootloader size during DFU, and also moving the bootloader also moves the FDS pages, so this change cannot be done with devices in the field.

Hi Elnar,

     So. If I add some code in my bootloader and IAR compiler show a error about over the flash space.

Then I must change flash start address from 73000 to 72000. Is it right?

Thank you.

John.

Yes, that is correct (or even further down depending on how large the increase in size is).

Hi Elnar,

    Thank you for your support.
