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

QSPI Flash = W25Q256

OK, I eventually found the solution. Alternative to downgrading stm32CubeIDE from 1.8 to 1.7 version, you can only copy and replace the below directory contents of the STM32CubeIDE 1.7:

C:\ST\STM32CubeIDE_1.7.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.0.0.202105311346\tools\bin

to the directory :

C:\ST\STM32CubeIDE_1.8.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.0.100.202110141430\tools\bin

of the STM32CubeIDE 1.8 and every things will work well.

The interactions here are going to be complex. The external loader can change the system state,and that might be a problem for the programmer.

You'll need to increase the verbose reporting level, and see if you can glean any information that way.

Perhaps instrument the code, and output via a UART or something, and understand how the system is functioning. The QSPI could be mid-erase.

Be conscious about what you're doing with the clocks, and how the QSPI is mapping. I'd generally recommend keeping things simple.

I faced this problem, I think some think wrong with STM32CubeIDE 1.8 ... Downgrade to 1.7 and it will work.

Absolutely you are right. The Problem was for the version of STM32CubeIDE 1.8

I downgraded to the STM32CubeIDE1.7 and the problem is solved.

I found the problem. According to these pictures(First for STM32CubeIDE 1.8 and Second for STM32CubeIDE 1.7)

The STM32CubeIDE 1.8 uses the STM32CubeProgrammer 2.9 and this makes the problems but the STM32CubeIDE 1.7 uses STM32CubeProgrammer 2.8 and makes every things work fine.

If there are other redeeming features of IDE 1.8, you might be able to substitute the v2.8.0 STM32 Cube Programmer in the binaries area

Yes I tried, but again the 1.8 one does not work. I think the GDB version is also effective on the existing problem

Hello!,

I'm having the same problem.

I'm using

STM32H743XI + MX25L51245G

STM32H743XI + MTQL2512

I made 2 custom external loaders for my board (one for each memory type), following the instructions descripted in a ST online course.

I tried STM32CubeProgrammer v2.9 and v2.11 but in both cases i'm having the error: "failed to download Segment[0]".

Only with version 2.7 it run ok.

Just to test, I have also tried to modify the Loader_Src.c/write(..) function to return always LOADER_OK, but the Programmer returning always the same error.

The erasing phase is ok.

Anyone can explain this problem and how to fix it for programmers version >2.7 ?

Best Regards.

Roberto.
