I am implementing DFU using my own transport to retrieve the binary image from AWS.
I'm developing in 2.6.0.
I am using the DFU TARGET libraries.
When I start my download I look at the first 512 byte block with
i=dfu_target_img_type ( buffer2,xblocksize); I get 1 (I think that this is DFU_TARGET_IMAGE_TYPE_MCUBOOT)
But I can't get past dfu_target_init().
When I run i=dfu_target_init(DFU_TARGET_IMAGE_TYPE_MCUBOOT,0,filesize,NULL); I get an error 19 (No Such Device)
When I run i=dfu_target_reset(); I get an error 13 (Permission Denied)
I believe the issue lies either in my prj.conf or my static partition.
Currently, prj.conf has
