Dear Nordic Semiconductor Team and Community Members,
I am currently working on an nRF54L05 project where I aim to use only the primary slot in MCUboot due to memory constraints. Instead of the backup slot upgrade mechanism, I want to implement a non-backup upgrade solution. My setup involves an SPI host (a USB chip with a RISC-V core on my board) that will transfer the .bin file to the nRF54L05, which acts as the SPI slave to receive the data.
Unfortunately, I have not been able to find suitable examples to adapt for this specific configuration. I have reviewed information on CONFIG_SINGLE_APPLICATION_SLOT and CONFIG_MCUBOOT_SERIAL, but it seems these configurations may not directly address my requirements.
Could you please advise if this approach is feasible? I would greatly appreciate any guidance, examples, or insights you could provide on how to achieve this.
Thank you for your time and assistance.
Best regards
