How to use "suit" in 54H20

[Gavin He]

When upgrading the firmware of 54H20 using suit, compilation errors occur when calling the flash operation functions (flash_area_open, flash_area_erase, flash_area_write...) and the suit_trigger_update function. Could you please tell me how to configure to use the suit function of 54H20 correctly? For example, how to set parameters in prj.conf and which header files need to be included... Thanks.

Hi,

For SUIT, see our docs on SUIT samples and also Device Firmware Update using SUIT.

(flash_area_open, flash_area_erase, flash_area_write...)

These are writing to flash directly right? Are you trying to do the DFU manually?

Instead, I recommend that you have a look at the above documentation and see if our recommended methods work for your use case?
