External Flash Loader gets "failed to download Segment[0]" error on STM32CubeIDE

[ARost.9]

Hello, I have made a custom external flash loader(.stldr) file for my STM32 based board and this file works great with ST Link Utility(Read, Write and Erase) are work fine and i can Program the board correctly. But when i try to use the created .stldr file by STM32CubeIDE the erasing process well done but when the downloading process gets start then "failed to download Segment[0]" error pups up.

Could any one help me with the problem?

MCU = STM32H743iit6

There's another thread discussing the replacement of the INTERNAL loader with one from the 2.6.0 era to resolve an issue like this.

I​ can't say I've needed it for my H7 loaders, but that might relate to my strategy.

I'll get you a cite when I'm at a computer. Look at post history for @N. SANTINI​ ​
