Flashing elf file in internal + external memory in STM32CubeIde

Go to solution

I've successfully created a custom flash loader for the STM32H7A3ZIT6Q with the MT25TL256 dual-quad NOR FLASH. I can erase, program and read the external memory in STM32CubeProgrammer with a dummy file. Flashing an elf file with external flash data fails.

Memory mapping also works in my STM32CubeIDE project. The project has some dummy data in the external flash section. It shows up in the Build Analyzer. I can export the external memory section to a bin file, which I can manually flash with STM32CubeProgrammer. If I debug my application I can see the dummy variable is correctly initialized and in the right location.

I use the following post-build command to export my bin file:

arm-none-eabi-objcopy.exe -O binary --only-section=.textqspi "${BuildArtifactFileBaseName}.elf" textqspi.bin

I've added my flash loader to a new launch file and I get the following output:

I've tried different versions of STM32CubeIDE. 1.11.0 and 1.10.0. Both cannot flash my elf file.

How do I get STM32CubeIDE to flash my elf file in external memory too?

I have a workaround.

In the linker file I no longer put the external flash after the internal flash:

.textqspi :
  {
    . = ALIGN(4);
    _qspi_start = .;        /* create a global symbol at qspi start */
    *(.textqspi)         /* .textqspi sections */
    *(.textqspi*)        /* .textqspi* sections */
    . = ALIGN(4);
    _qspi_end = .;         /* define a global symbols at end of textqspi */
    
  } >QSPI
  /*>QSPI AT> FLASH this didn't work!*/

This changed my elf file from:

In my launch file I added the external flash loader and set initialize to disable. I can now flash the elf file with STM32CubeProgrammer and I can debug, but not flash the external flash, in STM32CubeIDE.

I get the following error in STM32CubeIDE:

So it kind of works, but, I wish there is a way to get it working properly.

EDIT: I just discovered it works in STM32CubeIDE. With external memory initialize set to disable it will flash it anyway. But it will crash when I enable it. I don't understand the logic of it, but it works! Somehow there are occasional read errors with the flash chip so I reduced the clock speed from 70MHz to 56MHz

Seems to be failing on the INTERNAL memory erase.

Would perhaps suspect power supply, or VCAP pins/capacitors.

Any of the memory read/write protected?

Yes. That's what I did. I added the flash loader to the launch file. I have Enable and Init checked.

Hmm. That's odd. STM32CubeIDE can flash the internal FLASH without any issues and so can STM32CubeProgrammer if I don't select external FLASH. Nothing is locked or protected. We have several of our PCBs and they run without any issues, so power problems are unlikely.

The STM32 Cube Programmer log shows the erase of 0x08000000 .. 0x081D0000 failing (1.9 MB)

If it is conflicting with your External loader, then perhaps review that, but the log doesn't indicate it is involved, and the internal erase is failing.

The 0xD10 size downloaded to RAM matches the \bin\Flashloader\0x480.stldr for the H7A3

I read somewhere on this forum that the internal flash loader could cause problems. So I changed my 0x480.stldr loader to a version that was attached to some post. I think this was an older version. It could be that I broke it. But I'm not sure if I changed it for STM32CubeProgrammer or STM32CubeIDE. I'll have to check Monday when I'm in the office again.

0x480.stldr is not the issue, I've put the previous one back (file CRC32: EEC21F52). Flashing internal flash is fine, no issues. It only occurs when I try to flash internal + external.

I have a workaround.

In the linker file I no longer put the external flash after the internal flash:

.textqspi :
  {
    . = ALIGN(4);
    _qspi_start = .;        /* create a global symbol at qspi start */
    *(.textqspi)         /* .textqspi sections */
    *(.textqspi*)        /* .textqspi* sections */
    . = ALIGN(4);
    _qspi_end = .;         /* define a global symbols at end of textqspi */
    
  } >QSPI
  /*>QSPI AT> FLASH this didn't work!*/

This changed my elf file from:

In my launch file I added the external flash loader and set initialize to disable. I can now flash the elf file with STM32CubeProgrammer and I can debug, but not flash the external flash, in STM32CubeIDE.

I get the following error in STM32CubeIDE:

Exit.

So it kind of works, but, I wish there is a way to get it working properly.

EDIT: I just discovered it works in STM32CubeIDE. With external memory initialize set to disable it will flash it anyway. But it will crash when I enable it. I don't understand the logic of it, but it works! Somehow there are occasional read errors with the flash chip so I reduced the clock speed from 70MHz to 56MHz
