Erase a group of sectors before programming

[CTabo.1]

Hello,
is it possible to add a command in the startup tab of the debug configuration, to erase a group of selected sectors, before programming?

For example I want to erase sectors [16..63], but not sectors [0..15].

I have only found the "monitor flash mass_erase" command, but it erase all flash.

Thank you,
Carlo

Hello @CTabo.1 

I am not sure if there is initialization command for sector erase but you can do that using CubeProgrammer. Otherwise I suggest you similar posts : Solved: How to erase flash before programming with STM32Cu... - STMicroelectronics Community

Hello @FBL,
if I try to add the following pre-build step, as indicated in the post:

STM32CubeProgrammer is launched correctly, but only dumps the cli usage syntax.

make -j7 all
C:\ST\STM32CubeIDE_1.11.2\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.0.500.202209151145\tools\bin/STM32_Programmer_CLI.exe
-------------------------------------------------------------------
STM32CubeProgrammer v2.12.0
-------------------------------------------------------------------
Usage :
STM32_Programmer_CLI.exe [command_1] [Arguments_1][[command_2] [Arguments_2]...]
Generic commands:
-?, -h, --help : Show this help
-c, --connect : Establish connection to the device
...

However, if I append the command to erase selected sectors of flash

I have the following error:

make -j7 all
C:\ST\STM32CubeIDE_1.11.2\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.0.500.202209151145\tools\bin\STM32_Programmer_CLI.exe -e [16 63]

make[1]: *** [makefile:93: pre-build] Error 127
make: *** [makefile:61: all] Error 2
"make -j7 all" terminated with exit code 2. Build might be incomplete.

What am I doing wrong?

Thank you,

Typically it just erases the span of the application.

Your application could also facilitate erasure of non-application spaces via diagnostic or monitor type console.

Hello,
any suggestion about it?

Why if I launch STM32_Programmer_CLI.exe as a pre-build step, without command line options, it is launched correctly (but do nothing), and if I launch it with the desired command line options, like -e[16 63], I have an error saying that STM32_Programmer_CLI.exe is not found?

Thank you,
Carlo

From the log above, the built-in "sh" utility (busybox) does not like backslashes. Try somehow to replace all \ to \\ or to / or use cmd in the command: cmd /c "${cubeide_programmer_path}\STM32_Programmer_CLI.exe -e [16 63] "

Maybe the new CubeIDE has a bug in handling of / and \ on Windows -  it used to do the right thing.

Hello @Pavel A.,
cmd /c "${cubeide_cubeprogrammer_path}\STM32_Programmer_CLI.exe -e [16 63]" seems to be the correct way to invoke STM32_Programmer_CLI.exe.

Now the tool is launched, but it doesn't perform the erase operation because of the following error:

cmd /c "C:\ST\STM32CubeIDE_1.11.2\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.0.500.202209151145\tools\bin//STM32_Programmer_CLI.exe -e [16 63]"
make[1]: *** [makefile:93: pre-build] Error -1073741819

Even if I don't know what this return code indicates (I cannot find a return code list in UM2237), I guess that one of the problems is that I need also to specify the connection port.

So I have added the -c port=SWD option in the command line and now the erase operation seems to be performed correctly, as suggested by the output dumped on the console:

make -j7 all
cmd /c "C:\ST\STM32CubeIDE_1.11.2\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.0.500.202209151145\tools\bin\STM32_Programmer_CLI.exe -c port=SWD -e [16 63]"

Erase sector(s) ...

Is it right?

Looks much better. do you see the sectors actually erased with other tool such as CubeProgrammer GUI?

[CTabo.1]

Hello @Pavel A.,
yes I have verified with CubeProgrammer that the sectors are actually erased.

Thank you,
