Error: failed to download Segment[1] when programming with USB

KSOdin2 · ‎2024-08-22

I have written a program in the STM32CubeIDE V1.16, creating a .elf file for the STM32H723.

I then followed the Phils Lab tutorial https://www.youtube.com/watch?v=VlCYI2U-qyM to program the Nucleo development board using USB using STM32CubeProgrammer V2.17.

When I pull the boot pin high and press reset, it goes into boot mode, and the programmer detects it.

However, when I download the elf file, I get these errors:

Error: failed to download Segment[1]
Error: failed to download the File

It used to be segment [2] that failed, but I updated CubeIDE and and .IOC file and it changed to segemet[1].

I updated all my versions and followed solutions in other similar questions, though these are segment[0] errors

https://community.st.com/t5/stm32cubeide-mcus/stm32cubeide-upgrade/td-p/628738

Some solutions say to change a setting in the CubeProgrammer, but there's no obvious settings option I can change.

The code uploads into the MCU when the LED turns on, which indicates it does work. However, I want to clarify this error so that there isn't an issue in the future.

Thanks in advance for any help

Hello @KSOdin2,

I couldn't reproduce the issue on my end, could you share your .elf file for further investigation?

Thanks,

Amine.

After reading your comment, I just realised that I was trying to upload the .elf of the 64-pin H723 chip to the Nucleo board, which has 144 pins. I've tried a code generated with a .ioc file for the 144-pin version, and it now downloads, though it has no proper functionality apart from writing to Flash.

I tried to upload with the same method to an STM32H7A3 nucleo board with some code designed for that board. And it has the error for segment [2]

I've attached the .elf file as a .7z file to see if you have the same issue. I have changed some of the memory protection in the .ioc. I don't know if that changes it.
