DFU STMProgrammer issue

[MM..1]

I use CLI for flash F469 and same hex file flashed over SWD without error produce over DFU this. is this know issue ? Seems code is ok after both loads.

[Tesla DeLorean]

Where's the data going?

SRAM at 0x20000000. CCMRAM at 0x10000000

There shouldn't be any of that in the .ELF file / sections, as the startup.s code should be copying initialization data out of Internal FLASH

What other sections is the DFU file describing?

I test HEX and ELF file, and seems here linker generate section , but same file dont produce error if -c SWD is used.

and i dont understand why this section is in . Maybe my linker file need add somethink i use CCMRAM for some arrays. now is defined as
