Hello @Community member,
Could you specify the Wifi module used? and on which STM32 product? you may check Cypress WICED SDK version? For example, it is mentioned in H7B3-Discovery Kit User manual UM2569 that only Cypress WICED SDK 3.5.2 or later supports the hardware module.

We are using 43xxx_Wi-Fi, STM32F412ZGT6 and Version: Luna Service Release 2 (4.4.2)
Build id: 20150219-0600.
Are you saying WICED can build a DFU file?
I built an ELF with USB DFU class device using STM32Cube. I cannot get convert the ELF file to DFU that either "ST7 DFU Demo" or "DfuSe Demo". Using "DFU File Manager" to generate DFU...
I don't recall if the DFU Manager will take .ELF input
You might want to check this
I wrote a similar tool years ago, but not sure it dealt with multi-sections .ELF.
Not sure how complex your .ELF is.
DFU File Manager should be able to process a .HEX
I was able to use elf2dfuse to create a DFU file. DfuSe downloaded the file and verified. However when I reboot my board, the firmware was not updated.I have attached the ELF and DFU files. Also, I included the STM32Cube project et al that I loaded to handle DFU transfer. It enumerates, but not sure if it's actually programming the flash.
Operator error on DfuSe Demo verify, so ignore the above picture. Now I get:I'm guessing the firmware I have loaded in my board will enumerate as a DFU device, but does not actually program the flash.
The .ELF look built differently from the project
Assuming you have a loader of some sort, as the primary .ELF starts at 0x0800C000 address, and not 0x08000000
Attached are a couple of .DFU
The ELF from the project includes DFU. I use ST-LINK to download it. The other DFU is my project built with WICED. I'll eventually port the STM32Cube source into my project...if I can get it working.
When I try test1.dfu...When I try test2.dfu...
After power cycle, the original STM32 app is still running.
